OpenAI in my estimation has the habit of dropping a model's quality after its introduction. I definitely recall the web ChatGPT 5.2 being a lot better when it was introduced. A week or two later, its quality suddenly dropped. The initial high looked to be to throw off journalists and benchmarks. As such, nothing that OpenAI says in terms of model speed can be trusted. All they have to do is lower the reasoning effort…

Someone should create a daily benchmark site for Codex like they did for Claude

This is great. In the past month, OpenAI has released for codex users: - subagents support - a better multi agent interface (codex app) - 40% faster inference No joke, with the first two my productivity is already up like 3x. I am so stoked to try this out.

Try Claude and you can get x^2 performance. OpenAI is sweating

If i could use GPT-5.2 with Claude Code - yeah. Otherwise slOpus requires too much steering to get things done. GPT-5.2 just works

Earlier quoted context omitted.

5.2-codex is pretty solid and you get dramatically higher usage rates with cheap plans. I would assume API use is much cheaper as well.

people are sleeping on openai right now but codex 5.2 xhigh is at least as good as opus and you get a TON more usage out of the OpenAI $20/mo plan than Claude's $20/mo plan. I'm always hitting the 5 hour quota with Opus but never have with Codex. Codex tool itself is not quite as good but close.

Is there a plan like the $100 Claude Max? $200 for ChatGPT Pro is a little bit too much for me.

Whereas Claude Max 5x is enough that I don’t really run out with my usage patterns.

4.1 or 4.5? I did not need to steer Opus 4.5 at many points. A good description was more than enough

I do not think so. I have been using both for a long time and with Claude I keep hitting the limits quickly and also most of the time arguing. The latest GPT is just getting things done and does it fast. I also agree with most of them that the limits are more generous. (context, do lot of web, backend development and mobile dev)

this is for api only

Is it even possible to actually use codex any other way? Every time I’ve tried logging in instead of using the API, I’ve hit the usage limits within a couple of hours.

How do you get sub agents to work?

Add this to config.toml:

  [features]
  collab = true

tons of posts on reddit that they also significantly dropped quality

There are always people on reddit saying such-and-such model quality significantly dropped. Every single day there's a post like this in one of the Claude sub-reddits. It's virtually never substantiated with reliable evidence.
