Following up on my last post comparing Opus 4.5 and GPT-5.2. There was some back and forth in the comments about which provider actually gives you more runway per week, so I decided to track it

I ran some numbers based on my recent sessions. For me, a 5h coding window in Claude Code burns through roughly ~13-14% of the weekly limit. But with Codex, that same 5h block eats up closer to ~30% of the limit

And it feels like the Claude Code weekly cap is actually higher

Has anyone else tried to measure this? Curious if your numbers match mine or if you're seeing something different

I’ve been using Codex extensively for my software development job but decided to try claude code today with claude Pro subscription.

I tested it on common task that I has to do. In a working folder I have 11 repositories and each owns some part of a product I work on. I gave a task to explain the purpose of repositories and connections between them. Then I gave a task to fix deployment (add missing code) in one of the repositories.

The claude gave better description of repositories but nothing too crazy or deep. The code they suggested for debugging was the same. But claude literally used 30% of 5-hours usage while Codex only 3%.

Is there anything I do incorrectly or limits for claude are actually so low ?

EDIT: This is only asking about Opus 4.5 on Max 20x versus OpenAI's smartest model—so GPT-5.2-Codex set to Extra High or GPT-5.2 set to Extra High, whichever one is smarter.

TLDR: How do usage limits in the Codex harness with OpenAI's smartest model option compare to using Opus 4.5 in CC?

I'm looking into the expensive subscriptions. Can anyone with recent experience (e.g. the past few weeks) using both harnesses clarify some things?

1. Usage limits. Does Max 20x or Codex Pro have higher limits with their respective smartest model?

2. "Better"? When people say "codex is better than CC", I never know if they're talking about the Codex harness with...

• GPT-5.2-Codex

• GPT-5.1-Codex-Max (which OpenAI says is their "best model for agentic coding" as of 2 weeks ago)

• GPT-5.2

• GPT-5.2 Pro

• Any one of these with "high" VS "extra high"

I have been using Claude code for a long time, practically from the beginning when it was created, and it has completely changed the way I use AI. I don't know so much about code, but since AI is doing well with programming I started creating a couple of applications at the beginning to automate for myself and then streamline things at home. Claude Code, Sonnet 4 and Opus helped me a lot to develop technical skills and thanks to it I have things like automatic opening and closing of blinds or sending alarms when smoke detectors detect something, home lab and smart home is a big area of activities and possibilities.

Although there were sometimes limits I used Opus and Sonnet intensively. I didn't complain too much because the limits were sometimes reached at most an hour before the next 5-hour session. Things started to break down when weekly limits were introduced. Limits fluctuated terribly, sometimes it was better (but not like before the introduction of weekly limits), sometimes it was so bad that the limits in a 5 hour session ended after 1 hour.... My plan didn't change, the way I use it did too. The last 2 weeks have been tragic, because after about 3 days I used up the entire weekend limit. If the Anthropic team says that it does not change the limits then for me it is a simple lie, it is impossible to attract similar habits and use in a similar way so drastically change the limits.

I'll get to the main point, so as not to write too much. I've been testing Codex for a week having the usual $20 plan.

For 4 days I used similarly to Claude codex.... And only at the 4th day I had a limit. And not the cheapest model available just usually used the better ones. Codex has its downsides, but it can all be worked out and set up to achieve better accuracy similar to Claude, although in some cases Codex does better.

I know that OpenAI is probably losing a lot of money on this, and I know that it probably won't last very long, but even if they make it 2 or 3 times worse it will still be better than with Claude, who can with a $200 plan limit access after 1 day. Chatgpt's $20 plan and even more so the $200 plan is worth the money unlike Claude, which was great in the beginning and has now deteriorated.

Anthropic is going the way of Cursor, and it's not a good way because Cursor blatantly scams people, changes limits every different day and purposely worsens the performance of models through its layer just to make it cheaper.

At this point I am switching from claude to Codex and will gladly pay them $200 if necessary than $200 claude, which does not want to see its users.

And all because of the stupid decision of weekend capping. It was enough to ban forever those who used the limits 24 hours a day all week and overtaxed the resources, and give honest users full freedom, then of course because of some idiots who bragged here and created videos how claude works alone 24 hours a day Anthropic had to give a weekend limit. As far as I'm concerned they seized the moment to limit access to everyone because maintenance was too expensive, and that was just an excuse to implement limits.

Sonnet 4.5 will not save the situation, and if it goes on like this, OpenAI will garner more users than Anthropic. Personally, I feel cheated because I pay so much for only 1 day limit without giving any information that the limits are changing.

And if not OpenAI, Chinese models are available to choose from at a good price, or even for free

Time to wake up and be competitive.
