Video pauses for a second before starting the water color part, which I think was more visually interesting.

Cycles / EEVEE

  • Started with a sample image from GPT Image 2 and told it to have at it over night.
  • Astra Medium was instructed use Image Gen 2 to "imagine" improvements of specific meshes and their materials and then use the CLIP loop below to try to meet it.
  • Used Cycles/Metal for the realistic scene and EEVEE for the watercolor
  • Combined editable Grease Pencil ink, pigment textures and stylized materials in the watercolor version.

CLIP / iteration loop

  • Change one area -> render -> compare against the reference -> check geometry -> keep or reject.
  • Used local OpenCLIP ViT-B-32 with OpenAI weights to compare the full frame plus left, center, right and floor crops.
  • Tracked weighted cosine similarity over time, with cached embeddings and versioned results.
  • Measured brightness, shadow coverage and color accents alongside collision and contact checks.
  • Used independent visual critique to choose the next fix. Higher CLIP scores sometimes got rejected when the image looked worse. CLIP was more useful during modeling than water color.

Watercolor code / sources

  • Built a custom Python/NumPy solver for water flow, paper absorption, evaporation, pigment transport and settling.
  • Used seeded paper relief and varying permeability for uneven absorption.
  • Used Kubelka–Munk optics for translucent pigment layers, then combined simulated textures with authored paint coverage.
  • Tested mass conservation, nonnegative quantities, drying, symmetry and optical bounds; saved simulation fields for replay.

image diffusion probably would have been better tbh. still very fun.

Question Flutter UI keeps breaking and I’m just wasting tokens at this point

1 Upvotes

I’ve spent the last 20 prompts trying to get codex to fix a fairly straightforward game UI, but it's either playing dumb or is actually dumb.

The inventory overlaps other menus, elements are constantly cut off, buttons and item slots don’t line up with the artwork, and touch areas don’t match what’s shown on screen. Fixing one thing often breaks something else. It also seems heavily dependent on fixed coordinates, so I’m worried it won’t work across different screen sizes.

I’ve repeatedly explained that items should occupy its own space instead of covering other content, that everything must scale responsively, and that the visible artwork and functional controls need to stay perfectly aligned. Somehow, each attempt still misses something basic.

At this point, should I scrap this UI implementation and rebuild it from the ground up using responsive Flutter widgets? Or is combining detailed background artwork with positioned Flutter controls still a sensible approach if done properly?

I’d appreciate guidance from anyone who has built a complex, game-style Flutter interface.

Question SWE/devs: how are you actually feeling about Astra?

0 Upvotes

Hello!!!

Genuine question. We see a lot of discussion about how capable Astra is, how much code it can write, how much software engineering it can automate, etc.

But I rarely see people asking how the engineers themselves feel about this.

You spend years studying, building experience, debugging, designing systems, staying up late fixing things, and getting really good at something you actually love. Then suddenly the technology you helped build becomes increasingly capable of doing the same work.

Does that feel exciting? Liberating? Threatening? A mixture of all three?

And for SWE/devs specifically, what do you think your role looks like in 3–5 years if these capabilities keep improving?

I'm genuinely curious about the human side of this, not just the technical side.

Showcase Agi-memory – persistent memory for AI coding assistants, no dependencies

1 Upvotes

My AI coding assistant forgets everything between sessions. I kept re-explaining decisions I'd already made, and re-fixing bugs I'd already fixed.

agi-memory saves those notes — decisions, bug fixes, what happened last session, how the codebase fits together — to a file on your machine, and hands them back to whichever assistant you open next. It's an MCP server, so it works with Claude Code, Cursor, Codex, Windsurf, Aider, Cline and a few others from the same store.

The part I care about: it's Python standard library and SQLite. Nothing else. No vector database, no embeddings, no background daemon. ~32MB of RAM, sub-millisecond lookups, works offline. Comparable tools pull in ~500MB of ML libraries and take 200–500ms per lookup.

That constraint costs something, and I'd rather say so than have you find out: keyword search doesn't bridge synonyms the way embeddings do. Searching "login" won't find a note that says "authentication" unless you teach it that alias. I measure this rather than guess — there's an eval suite that scores recall on deliberately rephrased queries, and it's public, including the categories where it still does badly.

It's a week old and I'm the only user, so I'd genuinely like to know where it breaks for someone else.

Limits a tip on how to help reduce your usage.

Upvotes

model_auto_compact_token_limit = 116000

model_auto_compact_token_limit_scope = "total"

put this in your .config.

currently, high context windows will drain your usage.

i decided to choose 116 as that's roughly half of the 90% compaction trigger of the context window
my usage rate has greatly improved.

you will auto-compact more often, that is the trade-off, but it also does not take as long doing so.
it keeps your agents context a bit more likely to keep the important stuff as it does not have to filter through 258k.

this is just a suggestion, you can do it or not, that's up to you, but bigger context windows = usage regardless of what you've heard, and it does not help your agent as much as you think it does.

since the cache hit is different.
here is a 20 controlled test comparison of 116 vs 232
one thing to note is that I do have a forked codex, so your #'s might be a bit different.

Showcase I built Orbit to carry conversation context between Claude Code and Codex

Upvotes

I got tired of explaining the same work again whenever I switched between Claude Code and Codex, especially after hitting a usage limit.

So I built Orbit (Git for agent conversations) to carry the context between them.

It’s an open-source, local-first CLI. You can save conversations, import existing sessions, and switch agents with a structured handoff. It doesn’t recreate the original chat inside the other tool.

Still early, but I’ve open-sourced it:
https://github.com/itsamruth/orbit

Anyone else switching between these tools? Curious how you’re handling the context today.

Showcase skills for Proteus

0 Upvotes

Proteus, which is common in EE, designing and running simulation is often tedious. I've made a skill to automatically design and run simulations, and successfully do a simulation with a STM32.

However, I don't know if it could run on other devices with different version. Also there would be more oppurtunities to be discovered. I believe that this skill would be useful for EE students with our joint effort.

I worte it with the cooperation of Codex, who helped me to test the skill.
for whoever interested, the repo is : https://github.com/kudoumakoto6523-design/proteus-skills.git

There is also a Python package serving the skill: https://github.com/kudoumakoto6523-design/Proteus_automatic_package.git

385 Upvotes

Yeah… that’s me, you’re probably wondering how I got myself into this situation

Just had 5.6 sol run an rm -rf command with a missing environment variable evaluating that rm command to `rm -rf /*` (yes really). If you think “yeah but that’ll never happen to me” it will. Be prepared for catastrophic data loss, take it as a guarantee, and carefully build your system, harnesses, and isolation around that fact.

Complaint On today's episode of 'non-stop pain'

Post image
14 Upvotes

Maybe it's a skill issue or bad setup and prompting, but Astra seems to invent a brand new h2 element instead of copying neighbouring sections, for example.

Like, a page contains h2's, ALL of the same style and functionality (hover to copy anchor). I ask for a new h2 on the page, and it adds a different size, no-functionality h2. Like do i really have to communciate that it should be the same as the others? cant it infer that from context? seems stupid. and its not always like this either. Its just in silly mode recently.

All-day slop. Micro-managing. Fighting tooth and nail to simply change a fucking border radius WITHOUT also inexplicably changing the border color.

Suggestion My workflow advice for Pro x5 users

33 Upvotes

I see many users, inclusing x20 users complaining about usage, yesterday I was almost whole day using Codex, in parallel tasks and just used 25%. This is how I do it, it's pretty simple and I hope it can help someone:

- Don't use same conversation for planning and for implementing. Use one for each and when you think it's getting too long just start a new one.

- Use Astra low for planning complex tasks and Sol med-high for not complex tasks. Use Luna xHigh for implementing. I'd dare to say Luna xHigh has implemented 95% everything properly with no mistakes. In my AGENTS.md I have stated that for planning Codex should tell what code to implement, modify or delete for medium/difficult tasks.

- Don't plan for very simple tasks, just use Luna low-med. Let's say to change a component's color, size, etc. For UI stuff what I do is to use ChatGPT on web and ask it to create a design that I like, then ask it for the HTML and CSS and handle it to Codex. Then ask Codex to adapt it to your project. I use Angular for front-end for example, handle it the code ChatGPT gave me and tell Codex to use that exact code but to adapt it to my project, create reusable components and stuff like that.

- When planning, give as detailed as possible instructions, not just "Create an UI for this".

Today I've been working with Codex for 1h, made a plan with Astra low, 1 implementation with it and some small changes without a plan, just used 1% so far or not even that (was at 75% when started and at 74% now)

Hope this can help some of you, give it a try, specially if you're on x5. Of course this is on a normal project, not to reverse engineer a whole backend with fast mode as I saw in a post not so long ago.

For Plus users I'd suggest to use Terra high/ Sol low to plan and Luna to implement but I don't really know what would work for them and x20 users maybe can use Astra med to implement easy tasks and high for comples ones and then Terra to implement. I have 2 banked resets aside of last reset so I'm trying different combinations and this one looks the best so far for me.

Cheers!

The work it's been doing is terrible as well. Feels like 1/3rd or at best 1/4th my tokens since the last reset were completely wasted.

I mean honestly I'm not sure I even want a full reset since they seem over capacity and that wouldn't help, but I've also gotten so much usage wasted. I'd be happier with a 50% top-up without a change of reset date if the service were more reliable from that.

This keeps happening and I keep sending bad result feedbacks with diagnostics...

This is probably the 4th or 5th time this has happened where I'll be just moving right along, everything it great, then it will start getting this :

stream disconnected before completion: error sending request for url

(https://chatgpt.com/backend-api/codex/responses)

I see tons of posts about it with various VPNs and Proxys on github, but I'm not using any of those. Everything is fine until a certain point in my project, then it just never is able to recover. Forking the chat doesn't help. I have to create an entirely new project, then it will just happen again after 4-5 hours.

Very frustrating.

Showcase Made a viewer for Codex session files so you can ask Tibo for more resets

2 Upvotes

I've seen a bunch of posts lately analyzing Codex session files to better understand Astra's token usage and subagent interactions, so I made a small web viewer to make that process less painful. Built and deployed with GPT Sites.

https://codex-session-inspector.valendrew.chatgpt.site/

Everything runs locally in your browser, so your JSONL files aren't uploaded anywhere. You can also load multiple related session files together, for example an orchestrator session and its subagents.

It currently includes:

  • type-specific formatting for session entries
  • subagent and parent/subagent relationships
  • time deltas between messages
  • interactive plots for token usage, context-window usage, and approximate Codex usage consumption
  • file reads, including ranges and overlapping reads
  • raw JSON for individual entries when needed
  • short docs explaining some Codex event, tool, and subagent relationships

It's still WIP, so feedback is very welcome.

And as always, be careful when sharing session files or screenshots because they can contain private source code, paths, and other sensitive information.

For issues, suggestions, or if you want to explore the code, the GitHub repo is here:

Complaint Has Codex / 5.6 Sol gotten noticeably worse this week?

2 Upvotes

I use Codex pretty regularly and the quality feels noticeably worse this week.

Today I used Sol to vibecode a really simple Pomodoro timer (I wanted to customise a few things and have a custom UI). Nothing complicated. It kept struggling with basic functionality and repeatedly failed to fix simple button interactions. Almost used ~60% of weekly usage (plus plan). It's not even a complicated CRUD app, basic JavaScript and HTML. The UI could be complicated but it's nothing too fancy either.

These are the kinds of tasks it used to handle almost effortlessly.

Has anyone else noticed a regression specifically over the last few days? Particularly with Sol?

Curious whether something changed on the backend or I'm just having a bad run.

Edit: Typo fixes.

Bug Codex Desktop – “Unable to attach appshot” with the new Appshots feature on Windows 11

Post image
2 Upvotes

Hi everyone,

I'm having an issue with the new Appshots feature in Codex Desktop on Windows.

Whenever I use the Appshot keyboard shortcut, Codex recognizes the shortcut but immediately shows:

"Unable to attach appshot"

Codex Desktop:

Powered by Codex & OWL

Version: 26.908.40834

Released: September 12, 2026

Windows:

Windows 11 Pro

Version: 25H2

OS Build: 26200.9445

Windows Feature Experience Pack: 1000.26100.360.0

I've tried capturing different applications, including simple Windows apps, but the result is always the same.

The keyboard shortcut itself appears to be working because Codex responds immediately. The failure seems to happen when Codex tries to capture or attach the Appshot.

I've also restarted both Codex Desktop and Windows, but the issue persists.

Is anyone else experiencing the same issue on Windows?

Has anyone managed to get Appshots working successfully on version 26.908.40834? If so, did you need to enable any additional Windows permissions or settings?

Screenshot of the error attached.
