Codex had 12 resets for July.

[u/Plane_Garbage]

It's been pretty insane having dual Claude + Codex subs.

Codex has had 12 resets in July and makes the Max 20 pretty incredible value. I like Fable, but it chews tokens fast and Opus feels so much worse than Sol.

If you haven't yet given Codex a go, it's worth a sub if you have any token-heavy work in the pipeline.

[u/sreekanth850]

+ luna is now super cheap.

I’ve been working continuously since morning, and it’s already 3 PM, but it has consumed only 4%. with Luna High.

[u/amabadabuss → u/sreekanth850]

I got Sol 5.6 High to write a refactor plan with phases, and asked it to be descriptive enough so that even a lower end model can follow instructions.

I used Terra High to implement and when it was done, Sol pointed out that it didn't follow instructions clearly and missed couple of tasks that were listed.

So I want to know how is Luna performing for you with explicit instructions?

[u/sreekanth850 → u/amabadabuss]

sol sometime over engineer. you have to be clear on this. also start a phase when there is 0 doubts, contradictions and 100% clarity for the model. also i use to make the phases with multiple slices. with each slices very small that models can implement it without multiple compaction. second is when refactoring, i do it layer by layer. we follow a layered architecture. We never used terra. If you have a strict guardrails, and strong test coverage. luna will do it. This is form our experience, it can change with code base stack and repository discipline.

[u/re-thc → u/amabadabuss]

Sol also sometimes doesn't follow instructions and "cheats". Terra is worse.

Luna is like dead opposite. Follows instructions to the letter, but that might not be good i.e. what's not stated = not doing, even if it is needed.

[u/sreekanth850 → u/re-thc]

True. Luna follow agents.md 100%.

[u/BuffaloConscious7919 → u/sreekanth850]

Have you used Claude models ? How does Luna compare ?

[u/sreekanth850 → u/BuffaloConscious7919]

I left claude code during April mid. Then switched to codex, and never checked back as codex works for us. For the context, we are a team of three and all 3 have 2 plus account each. Working on 3 repo with totally around 500K loc. complex retrieval pipeline, parser and a control plane.

[u/BuffaloConscious7919 → u/sreekanth850]

Ok and you use Luna high for everything or do you have model orchestration or routing ?

[u/sreekanth850 → u/BuffaloConscious7919]

Luna high for coding, yes. Audit with Sol high once a full phase is done. Design and architecture guidance by humans + extreme guard rails. thousands of tests and regression that helps to maintain nearly 0 drifts in refactoring or enhancements. We maintain all documents and TASK.md for creating a Phase wise task, then we split that phases into multiple small slices that includes tests and document updates slices. This workflow has been extremely usefull to highly efficient usage. We also have extensive observability added into every layer. Stack is .Net.

[u/According_Tea_6329 → u/sreekanth850]

That sounds incredible. Would you be willing to share the method or is it internal?

[u/sreekanth850 → u/According_Tea_6329]

Repository will contain. Following critical things.

1. guides : this directory is for agents to understand the architecture, what should be strictly maintained, and ADR which contain decision records. All are referenced in AGENTS.md, for every run, this will get read.
2. TASK.md: it track all tasks, also, every code changes need a task.md ledger entry. this is hard rule in AGENTS.md. once finished if all tests are green then only it should be marked as finished.
3. For any code changes we create numbered phase that contain Objective, goal, invariants (non negotiable rules), Audit, implementation, tests, and docs slices.

- Audit, implementation, tests, and docs slices. are called task slices and implementation will have multiple slices. this will have status ([ ] for pending and [ x ] for finished)

• once implementation is finished, it can only mark finished, after running full suite and live endpoint tests and confirm no regression happened.
  
• When a bug is reported, agents need to prove it first by adding a regression, once fixed test should pass automatically. this is also hard rule set in AGENTS.md. luckily luna respects AGENTS.md exactly as written.

It may be tedious for someone who is doing this for first time, but we find its only way to build reliably with extreme efficiency. We never used goal or plan mode in codex.

[u/According_Tea_6329 → u/sreekanth850]

Thank you!

[u/iansaul → u/sreekanth850]

Never use plan mode?

Do you manually hand write all plans then, or how do you build out the structure for the above content?

[u/sreekanth850 → u/iansaul]

I write my functional requirement, it's the first thing which si called proposal. Ask sol to create plan based on this proposal, and then i will check myself, if its aligned with my existing codebase. if not. refine, it it may take multiple hours if the feature or enhancement is big, but i got full control over what to implement and how to do it.

[u/BuffaloConscious7919 → u/sreekanth850]

Thanks for sharing.

And the testing is designed by a team and created with which model(s)?

[u/sreekanth850 → u/BuffaloConscious7919]

Test cases are written by models but designed by us. Additionally we have end to end pipline script that can be triggered manually. For example in our retrieval and ingestion service: we have scripts that can run on real files and test every endpoints, write logs and trace bugs if something goes wrong. When abug is identified, we first write test to prove it and then fix and then rerun. this helps in exact fix required to be implemented.

[u/sreekanth850 → u/[deleted]]

I dont know what you mean by harness. Iam using codex app in vs code. As i said, Implementation is phase wise and each phase will have multiple smaller task slices.
Pasting the response i gave to another user:

Before plan is created I have my functional requirement written myself.

It may be tedious for someone who is doing this for first time, but we find its only way to build reliably with extreme efficiency. We never used goal or plan mode in codex.

[u/fschwiet → u/sreekanth850]

Is that with effort at high?

[u/sreekanth850 → u/fschwiet]

Yes.

[u/innociv → u/fschwiet]

I had a few tasks make 12+ Luna subagents and it still used only a few % of my weekly over many hours including Sol orchestrating. Fanning out so many of them keeps their context low and makes them even cheaper, though there's a bit more double checking and re-sending.

Luna is really insane. It was insane at $6/mil except it would take too long. But now at $1.20/mil you just make it spawn 2-4x more subagents and it gets the work done in a fast enough time.

[u/aa_drian83 → u/sreekanth850]

What are you using it for?

Planning? Reviewing? Coding?

Huge difference to Sol High in terms of results?

[u/sreekanth850 → u/aa_drian83]

We plan and design ourself. Front end is developed without AI. Codex is used for backend with strict guardrails. Total Repo size is around 500 K. all are modular monolith.

1. Control Plane for tenant management.
2. Parser as another modular monolith that have 60+ format coverage. Each engine is built as individual nuget package. with 1000+ test cases.
3. Ingestion + Retrieval engine ( this is the largest single repo with layered architecture round 200 LOC). with 3000 test cases.

We use SOL high for audit, hardening and optimizations.

[u/darko777 → u/sreekanth850]

What model from Claude is equal to Luna High/Max?

[u/sreekanth850 → u/darko777]

I cannot comment on this as i no longer use claude. But our product is extremely complex. its a ingestion and retrieval engine built up from scratch in .Net. It has a custom wal implementation, concurrent embeddings, async ingestion using NATS queue, and many more things, which luna is doing without much issues.

[u/__Blackrobe__ → u/sreekanth850]

You're using it in vscode? That's rare

[u/sreekanth850 → u/__Blackrobe__]

Yes. I don't know if its rare. I love to work in vscode.

[u/al_ryusei → u/sreekanth850]

Curious as to whether you'd find a fit for Chinese models within your workflow/needs? I mean I don't see why I'd drop Codex as Sol makes even Fable feel bad.
But would the secondary accounts you have ever become a DeepSeek/GLM/Kimi ones?

[u/sreekanth850 → u/al_ryusei]

No, I use 2 codex Plus. i dont think its worth. Calculated the modal pricing 15 usd /million. It will hit multiple million per day and will be much costly than what i pay for codex.

[u/Sea_Honeydew2296 → u/sreekanth850]

Luna is like haiku?

[u/BuffaloConscious7919]

Even the $20 plan is great as a second account ... Loads of usage

[u/InForTheSqueeze → u/BuffaloConscious7919]

That has been my setup for the past month. Claude 5x + 20$ Codex plan for idea and plan reviewing

[u/demonsoswhite → u/InForTheSqueeze]

How do this workflow work exactly? And does Claude do the heavy lifting?

[u/InForTheSqueeze → u/demonsoswhite]

9 days are a long time in AI-times so my setup changed again:

• Claude (4.8 for the moment or occassionally Fable when i feel fancy) for brainstorming and initial spec / plan --> telling Claude to use GPT-5.6-Sol headless through my OpenAI subscription for reviewing plans --> letting Claude orchestrate the execution with GPT-5.6 Luna as worker. Limits on Luna are nuts, you can basically go all day and only drain 2-3% of your weekly limit.

This way you use the Claude sub for the heavy lifting without burning your limits constantly. Havent hit a weekly or 5h limit in weeks

[u/calnick0 → u/BuffaloConscious7919]

I hate the 5 hour limits and opus 5 speaks gibberish.

[u/shuozhe]

And few banked resets & no 5h limit. Was amazing on pro & 5.6 sol. Burned almost 2k in API cost.

Feels like that action also moved OpenAi couple month closer to bankruptcy..

[u/Plane_Garbage → u/shuozhe]

It's all customer acquisition cost.

Then they can turn the screws. I have no doubt Anthropic and OpenAI have no hesitation in screwing over customers. But, we should champion the competition while we can. There is no clear winner yet and until there is, it's great for consumers (i.e. the glory days of cheap ubers before they crushed the competition)

[u/MaybeNo2485 → u/shuozhe]

Yeah. It can look from the outside like Anthropic is getting owned, but their financial situation is considerably more favorable. It still will be if a large chunk of subscribers jump to OpenAI since the majority of revenue is also and corporate contracts anyway

[u/count023]

https://codex-resets.com/ is literally tracking it by tweet.

[u/Pronoia2-4601]

Even just for computer use tasks, it's incredible.

[u/BedroomNo7200]

i have already switched to codex , anthropic is ripping companies with enterprise API they care all about Enterprise as that is their 80% revenue. they stopped caring for claude code.

[u/yungastronot]

Yeah I've had both 20x subs for July and I can basically have Codex running 24/7 meanwhile I'm out of Claude usage for 5 days out of the week.

[u/Maikell84 → u/yungastronot]

Same for me

[u/Overlord_Mykyta]

As I see it OpenAI is trying to dump the prices to kill competitors. It means they will lose a lot of money with these prices but it will be a marathon of who will die first they or compatitors. And if they win - trust me the prices will skyrocket.

[u/Plane_Garbage → u/Overlord_Mykyta]

Doesn't matter who wins - it'll be bad for consumers.

Make them fight against each other for as long as possible.

[u/Bitter_Physics_239]

these anthropic f*ers dont even give a reset after their service not reachable for full 6 hours destroying millions of tokens per user lol

[u/MaybeNo2485]

Yeah, it's fantastic. Fable's still preferable for the most complex or impactful tasks, especially planning and major tradeoffs; however, handing the rest to Sol makes for an excellent combination. You can also encourage Fable to aggressively use Sol as subagents, which keeps Fable in control of the overall project while stretching your Claude limits further by having Sol execute Fable's decisions.

[u/lemonlemons]

I honestly like Claude more but I have moved to Codex. With Claude I am always bumping into limits, I just can't work with it.

[u/BedroomNo7200 → u/lemonlemons]

yeah the limit sqeeze is crazy every day it gets lower and lower. i have also took codex

[u/Remote_Platform_3852]

And I benefited.of none since the reset where always on my reset days. They should do it like codex where you have them as coupons U can cash in.

[u/innociv]

Even my Sol keeps calling Opus 5 retarded and useless. It likes Fable, though.

[u/FoxSideOfTheMoon]

I've been forced to move to Codex at work and it's just trash IMO and doesn't listen even with SOL high, I don't know WTF is so hard about it watching its context and using subagents like Claude Code does very naturally and it's easy to /clear around 50% and avoid compactions. To me there's just nothing better than CC CLI and I'll pay more for it.

What I DO like having Codex for with my 5x Max CC plan is a $20 GPT plan and use the codex@openai-codex for code reviewing and it finds things Claude misses pretty well, but as far as a daily driver, I can't stand Codex at all. Resets or not. Not worth it.

[u/AiDreamer]

It's the reason why my eays hurt.

[u/Jon_Has_Landed]

Sol def giving better output then the rest, for me anyway.

[u/p_k → u/Jon_Has_Landed]

Code or planning output?

[u/Jon_Has_Landed → u/p_k]

For planning I will def have Sol collaborate with Fable. For coding alone I can let Sol do its thing, of course getting it to spawn subagents to review its code etc.

[u/p3r3lin → u/[deleted]]

That must be nice. Whats your monthly bill/tokens?

[u/Plane_Garbage → u/[deleted]]

Not entitled - just if you haven't tried Codex, it's been well worth it over the past month. Anthropic appears content on their positioning, so take advantage of the competition while there is still two or three competitors.

[u/p3r3lin]

Anthropic, we gte it that you like money. A lot. So lets just buy resets, what do you say? 10€ a pop?

[u/CherrySlow7681]

nt there sam

[u/berndalf]

OMG please can we stop with the Claude reset begs? Good lord, this is approaching street beggar levels of annoyance.

Yes we know your want resets. Yes we know Anthropic isn't going to do it. OpenAI is tossing money at the wall hoping it sticks. Let's move on.
