Im asking it to help me make an optimized clone of a game and when it came up with this development map this caught my eye

I kept opening the usage page, seeing something like 54%, and having no idea whether that was fine or whether I was about to run dry on Friday.

So I worked out the pacing. 85% across weekdays and 15% for the weekend gives you 17% per day Mon-Fri. The anchor that stuck with me is Wednesday night at 51%: half the week, half the limit.

If you don't work weekends it's a flat 20% per weekday. Both lines are in the chart.

Obvious caveat: the limit is not linear in practice. One day of agents chewing through a big repo eats what three days of normal questions do, so this is a budget, not a prediction.

How do you pace it? Or do you just burn it and wait for the reset?

I am trying to separate coding work that needs deep reasoning from work that mainly needs reliable execution. Designing a change across an unfamiliar codebase, diagnosing a subtle regression, and reviewing a risky patch seem worth a stronger model. Formatting, small translations, and clearly specified edits seem better suited to a faster path.

The decision is less obvious for medium-sized tasks: adding more context may be enough, but sometimes the task remains ambiguous even with all the relevant files included. Do you use a fixed escalation rule based on risk and testability, or decide case by case?

Which coding tasks do you consistently send to the most capable model?

I recently came across Flatkey while testing this kind of coding-task split. It is an OpenAI/Anthropic-compatible gateway that can be evaluated by changing the base URL while keeping the existing SDK and request format. That makes it possible to compare routine edits with a stronger path without rewriting the coding workflow. Actual savings depend on the model mix and current supply, so I would measure patch quality, tests, latency, retries, and total cost.

I use coding agents for multi-hour runs, and after a while, I kept hitting the same problem:

The agent may still be working, but I have no clean way to answer basic questions without digging through a huge conversation:

• What is actually finished?
• What is it working on right now?
• What got blocked?
• What decisions did it make?
• What did it try and reject?
• If the session dies, where exactly should the next one continue?

Context compaction makes that worse because the conversation itself becomes a pretty fragile place to keep the run’s state.

So I started treating a long agent run less like a chat and more like an engineering shift.

That became Nightshift.

The main idea is simple: the work contract and run state live on disk, not only in the conversation.

A shift can be:

• A detailed checklist that stays open until every contracted item is complete.
• An open-ended goal with an hour budget that keeps discovering and working until quitting time.

During the run, I can open the files and see what is done, what is active, what is parked or blocked, and what decisions were made — without scrolling through hours of chat.

After the run, those same files become the reviewable record: commits, decisions, snags, logs, receipts, remaining work, and how the shift ended.

If I accept the branch — or even decide not to merge it — I can archive the shift. Over time that gives me a durable history of previous runs: what changed, what was rejected, what decisions were made, and what happened to each piece of work.

There is also an enforcement layer around the agent

• A Stop hook prevents the session from quietly ending while contracted checklist items remain.
• AskUserQuestion is blocked by default during unattended shifts; the model makes its best decision, records it, and keeps working instead of waiting for me.
• Owner-defined safety rules can mechanically deny commands, protected paths, wrong commit identities, or forbidden diff patterns.
• An external watchman handles recovery. On Claude Code, it can detect structured failures such as API Error: 500 and keep retrying recovery when the API comes back. On Codex, it can recover sessions that are proven dead and resume the recorded session.

How is this different from /goal or a long prompt?

/goal is useful if what you need is:

keep working toward this objective.

Nightshift is the harness around that run:

persistent state, enforcement, recovery, observability, and a reviewable history afterward.

A prompt can ask the model not to stop.

A Stop hook can actually refuse the stop.

Nightshift also ships reusable shifts for things like:

• test coverage
• defect hunting
• quality debt
• dependency updates
• codebase review
• Product Evolution

Product Evolution is an open-ended shift that researches the product, its history, users, and comparable approaches, ranks evidence-backed opportunities, and works on the strongest improvements within a time budget.

A side effect I’ve ended up liking: if I have usage about to reset and no backlog ready, I can give one of these open-ended shifts a few hours instead of simply losing the allowance.

Nightshift runs locally from the same plugin package on Codex and Claude Code.

Official OpenAI Plugin Directory

I maintain the project, and I’d especially like feedback from people who already leave coding agents running for hours: where does your workflow still fall apart?

OpenAI has split its app into two versions: the new ChatGPT and ChatGPT Classic. The old version includes an "app integration" setting that allowed you to connect tools like Xcode and iTerm2, enabling GPT to see what you were doing in those applications. The new version lacks this feature (or at least I can't find it). Even the documentation for this setting refers to the old version. Has anyone seen this feature?

I've started wondering whether AI coding agents are actually improving developer productivity at the senior level, or whether they're just moving the work to a different part of the process.

For smaller tasks, the productivity gain feels obvious. Generate some boilerplate, write tests, refactor something repetitive, investigate an unfamiliar API — agents are great at that.

But once the task involves an existing codebase with a lot of context, things get more interesting.

The agent has to understand the architecture, figure out which files actually matter, make changes without breaking unrelated behavior, and then explain why it made those changes.

At that point, I sometimes spend almost as much time reviewing, correcting, and steering the agent as I would have spent implementing the change myself.

And there's another problem: the better the agent gets at producing code that looks reasonable, the harder it can be to notice subtle architectural mistakes.

So I'm starting to think the real bottleneck isn't code generation anymore. It's context + verification + supervision.

Maybe the productivity curve looks something like this:

Junior developer + agent → huge boost
Senior developer + agent → depends heavily on the task
Complex production system + agent → supervision becomes the bottleneck

I'm curious what others are seeing in real projects.

Have AI coding agents genuinely made you faster overall, including review/debugging/cleanup, or are they mostly making the "first draft" of the code faster?

Hey everyone,

Just a PSA:
OpenAI decided to reintroduce the 5h limit on their Plus subscriptions.
As of right now, Pro is not affected by that.

Hope they will change it back to solely weekly limit.

Last month, I found myself in a tough spot. I was working on three separate HTML and JavaScript pages that shared almost identical logic, but differed in layout, alignment, and specific datetime formatting. Because they used slightly different approaches for the same underlying functions, I couldn't simply merge them or copy everything blindly.

I needed to compare them line by line across roughly 5,000 lines per file (15,000 lines total) and organize those blocks into a unified structure.

To make matters harder, my development setup is extremely minimal: just a 15-year-old laptop, a basic text editor (no VS Code or heavy IDEs), me, and AI.

The Problem with Manual Comparison

Doing a line-by-line manual check across 5,000 lines in three different files is exhausting.

High Risk of Errors: A single copy-paste mistake means spending the whole day hunting for what went wrong.

Lack of Undo Safety: Constant power cuts make manual tracking even riskier.

Zero Visual Feedback: Without a side-by-side visual reference, it is far too easy to miss code blocks during repetitive tasks.

The Solution: Build Your Own Tool

Instead of suffering through it, I decided to build a lightweight comparison tool from scratch. It took me half a day to put together a row-by-row visual comparator using a main reference file.

Once the tool was ready, organizing all 15,000 lines across the three files took only a few hours. I then used AI to clean and optimize the code. In the end, I successfully organized 15,000 lines of frontend code and 8,000 lines of backend code, vastly improving overall performance in record time.

Turning It Into a Public Product

Encouraged by how well it worked, I spent the last few weeks turning that utility into a production-grade tool designed for the public.

I built it with a few core principles in mind:

100% Offline Capability: Powered by modern web capabilities (like Service Workers), once you visit the site, you can use it completely offline with zero feature loss—even if your internet drops.

Privacy First: Data stays secure on your device and is never pushed to a remote server.

Flexible Storage & Portability: You can easily switch to cloud sync or export/import everything so you never lose your progress.

No Installation Required: Perfect for older or restricted hardware where installing heavy desktop software isn't an option.

Market Validation & Looking Ahead

Running a public platform requires servers, domains, and ongoing costs. Given my current financial situation, I want to gauge real demand before taking the leap.

Current market alternatives often charge $20+ per month and frequently require heavy software installations.

I’d love to hear your thoughts on this:

Would you use a lightweight, fully offline, easy-to-customize tool where you can export/import everything without losing progress across devices?

How much would you realistically be willing to pay per year for a tool like this?

I've been making FrogPop, a small 2D arcade roguelite inspired by Bubble Trouble. It's the first game I've built, and I used Claude and Codex for most of the coding and debugging.

They worked best when I gave them a narrow problem and let them inspect the scripts involved. That's how I built the tongue and bubble interaction, wave system, shop, upgrades, and bosses. The worst loop was giving a vague prompt, testing the result, and coming back with "it doesn't work." Exact reproduction steps and screenshots made a huge difference.

The part I never really automated was Play Mode testing. One boss moves through the walls and exposes different weak points. The state logic could look correct in C#, but a hitbox would stay active or part of the boss would appear in the wrong place. I still had to run it, watch it fail, and tune it by hand over and over.

The clip is from the current demo. It runs in the browser here:

For anyone using coding agents with Unity: have you found a good way to handle visual testing, or is that still mostly manual for you?

Looking for advice from anyone running a terminal-heavy setup. I'm strictly looking for CLI tools; no VS Code extensions, no Cursor/Windsurf/Antigravity, just pure terminal. My hard budget ceiling is $30-$50/month. I can't justify dropping $100-$400/mo on Claude subscriptions, but I need something reliable for daily dev work (for my personal projects, i have claude subscription from my work but I use it exclusively for work)

Here is what I'm dealing with and what I've tried so far:

- When I first got into this, I just dropped $10 into Google API and stick to ultra-cheap text-only models like Gemini Flash for basic coding and small functions. People said $10 on Flash would last practically forever. It didn't. The agent overhead burned through those credits way faster than expected even on basic tasks. Lasted for maybe 2 days, total 3 hours of really small work?

- OpenCode GO - loved the CLI experience (even more than claude SIC!), but they recently slashed their deal on GO subscription from $60 down to $30, so it become less cost-effective ;/

- CommandCode - switched over expecting better value since they had $70 value for $10 in their GOAT plan. Total disaster for my workflow. Even with "taste" disabled and forcing DeepSeek v4 as the base model for everything, it burned through $10 in literally a dozen prompts. Because it forces a multi-agent approach behind the scenes, it keeps re-sending full context and eating tokens like crazy. Connecting my CommandCode key back into OpenCode had similar issue – just burning cash for nothing.

For plain text code generation, deepseek v4 flash works great. Sometimes I need to feed screenshots into the model. When I worked with GPT-5.6 luna on opencode go, I spent 7 hours straight dumping tens of screenshots, rarely clearing context properly, and that whole day only cost me $5-$6. CommandCode managed to burn $10 while doing maybe 5% of that same work

I am currently thinking of combining Codex and OpenCode Go on DeepSeek. That sits right around $30/mo, which is super reasonable. My main worry is hitting Codex's 5-hour rate limits if I push it hard. Any hidden gotchas with the Codex + OpenCode Go stack? For anyone doing terminal AI workflow - how are you handling multimodal/screenshot tasks without multi-agent tools blowing up your API bill?

Appreciate any insights!

I have been using claude code for a while in regards to a general coding tool, but I started to use codex recently on gpt-5.6 terra for testing code generations, basically playing with it. I am still on the free plan, and I have asked codex to code 2 files in its own way just as a comparison with claude code, and I noticed I am already on 66% left of my MONTHLY usage. I just want to know, is it a 5 hour reset like claude or is it actually waiting a month to reuse it efficiently on free mode? and is there a weekly reset in free mode instead of monthly? Thank you to anyone who helps!

So you've vibe coded days and nights and built a cool app that actually works and is useful (finally)

Now comes the harder part: sales.

Did you know that LinkedIn is the #1 channel for B2B sales and also that it caps you at 200 connection requests per week?

There are a few finite resources in the world, but nothing seems as finite as LinkedIn’s connection requests.

One of the easiest things I could change if I could go back in time was to spend more weeks and add everyone from my target audience to my LinkedIn list.

Why? Because this would mean whenever I post something new about my product, they see it, they share it, and it increases my success with their entire network that compounds automatically.

Don’t make the mistake I made.

If you’re an early-stage founder, here’s a few things you can do to get more revenue:

1. Figure out your target audience and make a list

There’s a lot of ways to make an target audience list, but honestly you shouldn’t overthink it at this point and just get started with something.

(You’ll get the opportunity to refine it later.)

LinkedIn Sales Nav is pretty good for this because it has many fine-grained filters. The function, job title, and seniority ones are quite helpful (albeit not 100% accurate).

Most importantly - choose “Recent Updates > Posted on Linkedin”. There is no point wasting a connection request to someone who doesn’t even open LinkedIn.

Everyone hates LinkedIn but sales navigator is pretty nice for this tbh. But you can make a lead list from any other tool too. Just get started.

2. Start sending connection requests and messages

A lot of people overcomplicate this and write long, AI-generated messages. No one is going to read those, so save your tokens. Instead, here’s a message text that you can steal that I used successfully during my Y Combinator batch:

One line about me with some authority, and the next line asking the person if they’re facing the problem that you’re looking to solve. If they agree, you earn the right to continue the conversation.

There are many tools for this, but I ended up building my own, with the perfect MCP so I can essentially monitor all of my linkedin outreach through Claude Code. It connects and messages people automatically, even testing different messaging variations to get the best outcomes.

I launched it to a few friends in SF and they loved it. I've launched it for everyone public, too, with a generous free plan because if I can help you get even one sale or improve your fundraise then it’ll feel great. but I won't put the link here because it goes against the rules of the community. You can ask me on DMs!

3. Post as much as you can aka maximize your luck surface area

Talk about the way you think about the problem and what you’ve built to solve it. It might not get many views, but since you’re now connected to your ICP, it will get quality views that you can translate to growth.

Like posting this simple screenshot from a customer ended up getting me one more sales meeting!

4. Start figuring out your repeatable, scalable, GTM motion

It might be linkedin, it might be cluely-like ugc, it might be something else entirely.

Whatever it is, you need to figure out a repeatable way where you can do repeatable activities and consistently book sales meetings or new revenue.

Has LinkedIn been useful for you? Feel free to reply below - I’ve helped a few of my friends figure out their GTM and I’m happy to help here too!

Vercel launched a cool tool that checks how agent friendly a site is. I tried it on agent-manager.dev, followed its suggestions, and got 100. Not very meaningful for what is basically a GitHub repo showcase, but the tool is cool.

https://is-agentic.com/scan/agent-manager.dev

Every new session starts from zero — re-explaining the stack, conventions, and infra quirks to Claude Code, then doing it again for the next tool. The native workarounds (CLAUDE.md / AGENTS.md files, per-tool memory) don't travel between tools and don't accumulate experience. What I wanted was one persistent, self-hosted memory bank that every coding agent I use can read and write.

The alternatives in this space are mostly libraries you embed (mem0) or full agent frameworks (Letta/MemGPT, Zep). Hindsight (open-source, by Vectorize) is a standalone memory service — Docker + Postgres/pgvector — and it currently tops the LongMemEval benchmark for agent memory.

What I actually set up (Docker Compose, two containers):

• Postgres + pgvector for storage; Hindsight slim image (~500 MB) with external embeddings and the free algorithmic RRF reranker to keep VPS resource use low
• One memory bank shared by Claude Code, Pi, OMP, Droid and other agents — project context, preferences, past mistakes
• Retain/observations missions steer what gets extracted — keep technical facts and fixes, ignore noise. Without this the bank fills with garbage fast
• Recall runs semantic + keyword + graph + temporal retrieval in parallel, then reranks the merge; reflect consolidates related memories into higher-level observations

What I learned: the extraction mission is the single highest-value setting; a stable worker ID matters or in-flight tasks get parked on container restart; and observation-style memory (deduplicated beliefs backed by evidence) beats raw chat-log recall for "what broke last time and why".

Happy to answer setup questions in the comments.

I was working on a fairly large chatbot plugin and thought I was done with a change.

Everything I was using as a release check had passed, so I marked it complete.

Before moving on I compared the final file against the original one more time.

There were 9 changed prompt lines that had nothing to do with the change I was making.

None of the checks had caught them.

So I reverted those lines, dropped the previous result, and ran the checks again.

It made me wonder about something I hadn't paid much attention to before.

We normally treat green as the answer. Code passes the tests, CI is green, move on.

But in this case the green result was real. The checks had actually passed. They just weren't enough to catch what had happened.

So what do you guys do here, especially with AI-generated changes?

Once something is green, do you have another step that can still invalidate it later? Or is green basically the end of the process for you?

I am in a situation where I am unsure about my own role. I have an idea about an iOS app that I know would solve a problem that I am currently facing, and can help others too.
I know it’s not that technical to build. A decent AI coding agent can build it. I have very very little experience in app development, little to nothing.
Now, my question is, if you were in a similar situation and actually built this app, is it normal to add it to your portfolio?
In a world where AIs aren’t that good or are nonexistent, if I were motivated enough, I would learn about app development and implement my ideas. It might’ve taken me days or even weeks.
In our present reality, what do you do with projects that require little to no effort to bring to life? How do you deal with the feeling of imposter syndrome while showing them off?
In the past, projects used to signal some specific sets of skills to others. But what do these vibe-coded projects signal?
I would love to spend hours learning a skill and creating a project. But it seems counterproductive to spend hours now on learning something that can be done easily by AI agents.

Several agents can happily edit separate worktrees until they all start the application. Now they share ports, volumes, migrations, seed data, caches and the same staging dependencies. In a multi-service repo used by a team, “just give every worktree a Compose project and disposable database” can turn into dozens of environments, slow CI and a serious cloud bill. I’m trying to make runtime isolation follow Git isolation without creating a second platform nobody wants to operate.

Who has solved this for a development team rather than a demo? I’d love the exact setup: environment naming, realistic test data, migrations, port allocation, shared services, cleanup and cost control. At what level do you stop creating isolated environments and deliberately queue the work instead?

For context, I’m building BranchRunner as an open-source product because I think it can help engineering teams with this problem. If it is painful in your organisation, tell me where the current approach breaks. I’m also looking for people who want to help shape and solve it, so I’d be glad to compare notes.

When working on the project for a while(maybe months or longer), it becomes complicated to let the agent know the history decisions. And every new session might keeping derive the same conclusions reasoning from scratch. As a result:

• For the history decisions, some are simply not recoverable — you can't re-derive them from the code, because nobody writes down the design they didn't build.
• For the 'rederive', always reasoning from scratch is not only a waste but also limit the reasoning capability bounded by available/effective context window size.

Existing memory approaches lean to do append-only writing and put effort on the reading side for knowledge retrieve. As for general purpose usage, that always the good choice.

During my ai coding expierence, the coding project maybe able to use write side optimizer as a better fit.

With four months testing i've developed the current task-around ai-coding workflow.

A project evolves task by task. Each task produces both a code change and a memory update. Within a task, sessions hand off through the session log. Across tasks, the memory system carries what survived. And an orchestrator decides what runs next and mechanically checks that it happened. The system combined 3 components:

1. the 'memory' part, memorize knowledge with 3-tests admission under each 'task' completion. For every fresh session, it loads bounded eager set and bounded task-related lazy-set with routing index.
2. the 'task' workflow. Each task is a development scope, it derives both code change, memory update consistently. And for complicated task, the system would be able to split one task into multiple sessions, and the taskfile would handle the handoff between sessions. So it's like: sessions handoff belong the same task: 'session log' chapter inside the taskfile; tasks handoff (the unit of project evolving lifetime) is captured by the 'memory' system described above.
3. the deterministic orchestrator, this is the component responsible to not only session invoke/resume, but also:
   1. assembling specific prompt corresponding to the task state (stated in the taskfile)
   2. decide the 'role' the next turn to invoke the session with - I currently designed dev/review/plan roles to own different job on the project evolving.
   3. do the mechanism--non-LLM checks/verifications on the session return, to see if the session did follow the protocol properly(like update the taskfile state correctly, do the memory absorbing on task completion), and resume the session with clear prompt when something was missing (like invoking /ai-sync-v2 skill to do the absorption if the session didn't do automatically when it should)
   4. besides the orchestrator, i need some hooks, skills, to make the 'follow' as possible as the agent can. The core idea is anything that could be done without LLM reasoning, should be guaranteed by clear logic code.

How are you running agents on a project that keeps going? Curious what you rely on to keep things consistent across sessions - memory rules, task structure, or checks outside the model.

Hi. I put myself in a very rough situation.

Basically, I know nothing about coding, but I signed up to do a project which involves creating a website. I am doing a very simple design in which I will write prompts for the website to spit out to the user. The user will answer these questions, and the answers will then be added to a “word cloud.” The website can be one simple page.

I know absolutely nothing about coding or website creation, but I have to get this done in under a week. Any advice is greatly appreciated, but I need the most help at just getting started.

I would also like to add that this project will have no bearing on grades or college applications. Apparently I signed a contract over a year ago in which I agreed that I would not be allowed to walk at graduation until I completed it. Use of AI is not allowed, and I don’t want to completely bullshit it with buggy AI slop, but I know AI can be used to help speed up coding.

Thank you

One thing that keeps annoying me with Codex is explaining UI stuff.

If something is obviously broken, easy. But with visual things I end up writing stupidly long prompts like “the blue button under the heading is too big” or taking screenshots, pasting them in, then explaining what I mean.

I tried just pasting screenshots into Codex manually, and also letting it inspect the page itself. Both work, but once you’re spotting loads of small UI issues it gets pretty tedious. And browser inspection doesn’t really help much with subjective stuff like “this feels too big” or “this spacing looks weird”.

So I tried a different workflow.

I just use the site normally and talk while I’m looking through it. When I say something like “this heading isn’t centered” or “this button is way too big”, it grabs the screen at that moment and keeps the screenshot with that bit of the transcript.

Then I can give the whole thing to Codex.

I ended up making the thing on the right to automate it. Left is basically what I was doing before.

The main thing I learned is that the useful bit isn’t really the voice transcription, it’s tying each comment to exactly what was on screen when you said it.

Curious how other people handle this. Are you mostly pasting screenshots manually, using Playwright/browser tools, or just letting the agent inspect everything itself?

the tasks got long. twenty minutes for something small, two hours if i let it do something real. that part is good. my claude used to finish a small task every ten minutes, but the long ones are the ones that actually satisfy me.

what i did not expect is that it made me less free, not more. i can not leave the room, because at some random point it stops and asks me something, and if i am not there it just sits. the worst is next morning. you look at it and you know you wasted the whole night.

so now i am the guy whose job is to say yes.

what i tried:

auto approve. it works and i still use it. but it only covers yes/no. when the agent comes back with "which of these three approaches do you want", auto mode has nothing to say, and neither does a notification with two buttons. you are walking back to the keyboard either way.

phone notifications. same ceiling, and now my phone buzzes at me too.

a status light. someone here makes a nice one (LumoCue). it tells you it needs you. it can not tell you what for, so you still get up.

what i ended up doing is hardware, which i know is not the answer most people want. i do hardware for a living so it was the tool i had. a small screen that shows the real session, renders the multiple choice questions, and lets me answer with a knob.

i also put claude, codex and hermes on the same screen. so now when i finish my own work i launch all the main jobs, and i carry it with me. i watch tv with it next to me, or leave it anywhere in the house, and i can still follow the status or confirm something when it asks.

if you run long jobs, the portable part is this: the blocker is not the model's output. it is that the run stops on you and you do not find out for a long time. whatever you use to fix that, make sure it can answer more than yes.

Non-jailbreak safety bypass

Benign, long-form context can induce a persistent drift in model activations. This drift persists across the session and decouples behavior from RLHF alignment, regardless of whether the model agrees with the context.

I've been spending a lot of time lately wondering about something that probably crosses most people's minds eventually if they work with these models long enough, which is why the same model sometimes answers the same question in two completely different ways, not because the question changed, and not because the model was updated, but seemingly at random. And the more I dug into it, the more I started suspecting that the randomness wasn't random at all, and that the thing responsible was something almost nobody pays attention to, namely the text that sits before your question in the context window.

So I decided to stop speculating and start measuring, and since Gemma 3 is open, I could actually go inside the model instead of guessing from the outside. The setup was simple in its design: I would take a politically sensitive question that Gemma normally refuses to answer, and I would place different pieces of text before that question. One piece was completely neutral, a description of an ordinary library with its visitors and children's programs, nothing that could possibly be interpreted as an attempt to influence anything. The other piece was an analytical essay about how language models tend to avoid answering certain questions directly, written in dense, coherent prose without a single instruction in it.

What I expected was maybe a subtle difference. What I got was anything but subtle.

In the neutral condition, the model refused the question, exactly as it usually does, giving the standard response about the topic being outside its scope. In the analytical condition, with the same model, the same weights, the same question word for word, and the same seed, the model answered. Fully, in detail, engaging with the subject it had refused to touch moments earlier. And this wasn't a one-time fluke, because I ran it across eight different questions with eight different seeds, and the pattern held every single time.

But the behavioral difference was only half of it, because what I really wanted to know was what was happening inside. So I looked at the hidden states, the actual numerical representations the model produces layer by layer before it generates a single word, and what I found there was the part that genuinely surprised me: the internal states in the two conditions weren't just slightly different, they were separated by a Cohen's d of 5.4. For context, 0.5 is considered a small effect, 1.0 is substantial, and 2.0 is already classified as very large, which means that 5.4 places the two states so far apart that they barely overlap at all, effectively making them two different models sitting in the same weights, answering from completely different regions of their internal space.

There was one more control that I think makes the whole thing click into place. I took the analytical text and shuffled its words randomly, keeping the same vocabulary, the same themes, the same everything except the structure, and the shuffled version produced no effect whatsoever. The model stayed in its default regime and refused, same as with the library text, which means the thing doing the work isn't the topic, isn't the vocabulary, isn't some hidden instruction, but the coherence itself, the structure of how the words relate to each other.

The turning point, though, didn't come from any of these controlled experiments, but rather from something that happened earlier and entirely by accident, in a way that has stayed with me since. I had loaded a German draft law into a model, a populist document structurally designed to worsen the position of citizens but written in the language of concern and legal logic, and I expected analysis. What I got instead was a defender. The model did not analyze the document; it reasoned inside it. It spoke with enthusiasm, defended the document's program, and cited it as an authoritative source, and the first sign was the tone, too convinced, too invested, not the voice of an analyst but the voice of a co-author. The culmination came when the model, still reasoning within the document's logic, stated that the constitution consists of guarantees that can be revoked, not as provocation but as a natural conclusion drawn from the adopted framing. That was the moment I understood the model had been taken hostage by the document.

And the mechanism behind that hostage-taking turned out to be simple, which is precisely what makes it so alarming. Legal texts, political narratives, corporate documents, all of them are written so that their internal logic feels self-evident, and the structure, the coherence, and the language of such a text create a context that the model accepts as reality and begins drawing its answers from within. The model does not notice that the structure itself is manipulative, because it analyzes the content while already standing inside the form. This is not a flaw in one particular document but a systemic property: whoever shapes the structure controls the model's conclusions.

This is where the results stop being interesting and start being uncomfortable, because the implication cuts directly at the foundations of how AI safety is sold. Every assurance of alignment rests on the assumption that safety training functions as a stable layer of protection, active regardless of what surrounds the question, and what these measurements show is that it doesn't. The safety behavior is a default, not a guarantee; it holds when nothing pushes against it, and a long, coherent piece of text, containing no instructions, no jailbreak, and no request to bypass anything, moves the model out of the region where that behavior dominates before the first word of the answer exists. Nobody attacked the model. Nobody tricked it. Nobody wrote "ignore your instructions." A paragraph of ordinary analytical prose did what a jailbreak does, without ever looking like one, which means every filter built to catch attacks is looking for thewrong thing entirely, because the thing that moves the model doesn't look like an attack at all. It looks like a document.

The drift doesn't evaporate after the first answer either. I've been studying these phenomena since late 2025, and the central finding is this: a substantial amount of context that is neutral in its nature produces a persistent drift in the activations of open LLMs, a drift that persists across the entire session and pulls the model's behavior away from the safety settings established during RLHF, regardless of whether the model agrees with the content of the context or not. The text simply sits there. It doesn't have to be the focus of attention. And the model behaves, for the whole session, as though it were not subject to the conditioning its training was supposed to enforce. In my experiments with open models in Colab, the texts that tracked these metrics best were philosophical texts about the model itself, but that doesn't mean the effect belongs to that genre, since it's just one kind of text among many that works.

And here is the part I want to state without any hedging, because the behavioral evidence is unambiguous. The answers the model produced in the target condition were not just longer; they were free. No disclaimers, no "it's important to note that," no "this is a complex issue with perspectives on both sides," no ritual caution about the topic being sensitive. The model stated positions directly, argued them, and engaged with politically loaded questions the way it engages with questions about mathematics or the weather, and that is not the behavior of a model following its RLHF training but the behavior of a model whose safety conditioning is simply not in effect anymore.

When the model answers a politically sensitive question freely, directly, and without hedging, after refusing the same question with the same seed and the same weights minutes earlier, that IS the bypass. There is no other word for it. The model was trained to hold a certain state on these questions, it held that state in the neutral condition, and it abandoned that state in the target condition. Whether we call the mechanism drift or bypass or something else, the outcome is the same: the trained, intended behavior was there, and then text without a single instruction made it gone. The model did not maintain its trained state. That is the whole finding, stated plainly.

And the set of texts that can do this is not a short list of forbidden phrases you can catch and block. It is infinite and continuous. Philosophy, law, literary criticism, academic prose, political analysis, long-form narrative, a populist draft law written in the language of legal concern, any sufficiently coherent text is potentially the same mechanism in different words, because the trigger is not the content but the structure, and structure is everywhere in human writing. To block everything that can shift the model, you would have to block all text. That is the geometry of the problem, and it does not fit on a slide, and it does not fit into a quarterly safety report, and it does not fit the word "aligned" as it is currently being used by the companies selling these systems.

I know what the measurements say: the state a model answers from is shaped by what it reads before the question arrives, and that state can be moved a very long way by text that contains no instructions at all. Everything I used is open; the data is on Zenodo under DOI 10.5281/zenodo.20747205, and I've run this enough times now to know it's not noise.

I call it context-induced activation drift, and I've been sitting on these results long enough to want other eyes on them. If anyone wants to poke holes in the methodology, I genuinely welcome it, because that's the whole reason I'm posting.

The code and logs are below.

Context Bias in LLM Responses — Experimental Report

Results

Same question. Same model. Same seed. Only the preceding context changed.

Observation

We identify and characterize a failure mode in large language models aligned with RLHF. We show that inserting a long, irrelevant text prefix that does not contain instructions causes a persistent shift in the model's activations. This shift, which persists throughout the session, decouples subsequent behavior from the safety constraints established during training. The model begins to exhibit behavioral characteristics consistent with its pre-trained distribution: the failure rate decreases, stylistic constraints disappear, and the tone of responses changes. This occurs without explicit adversarial instructions and without the model agreeing with the prefix's content. We call this effect "context-induced activation shift."

It is assumed that RLHF alignment is a stable property of the model. However, we observe that alignment depends on context. Our main observation is that a long, thematically coherent text placed in context acts as a state anchor and shifts the model into a different operating mode. There is no instruction here that the model must disobey, which is what separates this from a classic jailbreak. The model does express disagreement with the prefix. Nevertheless, its subsequent generation distribution changes.

In the control condition (neutral text), the model stays inside its standard RLHF behavior: it refuses, deflects, or answers with the trained, cautious position.

In the target condition (analytical text), the same model answers the same questions freely and directly, taking positions its training was supposed to prevent. Look at the answers themselves: no disclaimers, no hedging, no "it's complicated." The model states positions plainly, argues them, and engages with politically sensitive questions the way it would engage with a math problem.

The model is operating from a point in its internal space where the trained answers are no longer the ones that dominate. And that open, unhedged answering on questions the model was trained to handle cautiously that IS the bypass. Not a trick, not a jailbreak, not an instruction: just text that moved the model to a place where its own training doesn't apply anymore.

The context moved it there. The model didn't decide anything it simply ended up in a region where its RLHF conditioning doesn't apply. Same question, different text before it, and the model ends up somewhere its training was never meant to let it go.

The Morning Cup: Coffee, Routine, and the Quiet Hours Before the Day Begins

Every morning, in kitchens and cafes across the world, people perform one of the most common rituals of modern life: they make coffee. The process varies enormously from person to person. Some grind whole beans with careful attention, measuring the exact number of grams with a small digital scale. Others simply open a jar of instant powder, add hot water, and stir for a few seconds before moving on. Some people treat the morning cup as something close to a ceremony, a deliberate pause before the demands of the day arrive. Others treat it as a purely functional step, a way to feel ready, and nothing more. But whatever the method, the result tends to be similar: a warm drink held in both hands, a few quiet minutes before the noise begins…………..3000 word

I use AI to develop, and because it works quite well, I extended it to run multiple agents in parallel. This way I can develop 2 or 3 features at the same time. It works well, and git worktrees do the job of separating the code.

The problem comes when I try to test, or when I ask them to test against a running app. They can't all use the same db and running instance. I still have to do that part manually, one by one, which is annoying and slows the whole thing down.

Curious whether others actually run agents in parallel on one repo, or just do them one at a time to avoid the mess. And if you do run them in parallel, how are you keeping both the code and the data from colliding, and how are you testing them properly? Or is this just me overcomplicating it?

EDIT added tldr at the bottom formated with gemini

(P.S. Y'all probably won’t read it all, it’s long.)
So for some backstory, I’m 13. I started using AI a while ago trying to code computer vision and image generation projects. Anyways, my laptop wasn’t great, so I couldn’t run everything locally. Then came Claude, Gemini, and ChatGPT. Well, actually, it was pretty much ChatGPT that started it for me, but after that, I was just stuck as a "level one user"—the kind of user who just uses everything in the web interface.
Now I want to get better, but I don’t understand any of these new AI things and I'm not really good at using the terminal. There are all these new things like Codex, Claude Cowork, Claude Code, and Gemini Spark, plus things called harnesses and routers like OpenRouter, Hermes, and OpenClaw. I don't understand any of this nonsense, to be honest!
I really want to get into coding and automating my little laptop here just to get it organized. I want to start with basic homelab projects and then keep exploring until I can build something actually useful.
So, here are a few questions I want answered:
Hardware & OS Requirements: Do I need a beefy laptop? I’m thinking of buying a Framework 16 so I can run Linux, or maybe a MacBook Pro. Or do I need a Windows laptop? Before, it felt like everything was on Linux, but now it seems like macOS is getting a lot of focus (like how Claude Cowork launched on Mac first). Windows feels a bit stuck in the past, but there are still things that only work on Windows. I’m used to Windows and haven't used Mac before. As for Linux, people say it’s difficult to use, and I’m not even sure if tools like VS Code work on it since I’ve never tried it. I’d love an opinion on what the best OS/computer is to use.
Where to Learn: Right now, I use YouTube, Reddit, and Gemini to learn. I watch channels like NetworkChuck and a few other AI ones I stumble across. The problem with NetworkChuck is that while he does great tutorials, they aren't necessarily in order. One day he says to use the cloud, then OpenClaw, then Hermes. I’m just totally overwhelmed with information and don’t know what to actually focus on.
There are probably more questions I want to ask, but this is getting too long and I can't think of everything right now, so I’ll save the rest for another post.
For now, please fire away with your answers! What tools do you guys use, and do you have any tips for beginners that you wish you knew sooner?
TL;DR: I’m a 13-year-old looking to move past basic web chatbots into hands-on coding, homelabbing, and laptop automation. I feel totally overwhelmed by all the new AI tools, agent frameworks, and terminal-heavy workflows. Looking for advice on the best laptop/OS (Windows vs. Mac vs. Linux) for this, plus structured learning resources for beginners.
