With $20 gpt plan you can use xhigh no problem. With $20 Claude plan you reach the 5h limit with a single feature.

Ha, Claude Code on a pro plan often can't complete a single message before hitting the 5h limit. Not hit it once so far on Codex.

This, so frustrating. But CC is so much faster too.

In my personal experience the GPT models have always been significantly better than the Claude models for agentic coding, I’m baffled why people think Claude has the edge on programming.

I think for many/most programmers = 'speed + output' and webdev == "great coding". Not throwing shade anyone's way. I actually do prefer Claude for webdev (even if it does cringe things like generate custom CSS on every page) -- because I hate webdev and Claude designs are always better looking. But the meat of my code is backend and "hard" and for that Codex is always better, not even a competition. In that domain,…

Ah and let me guess all your frontends look like cookie cutter versions of this: https://openclaw.dog/

As long as China continues to blitz forward, regulation is a direct path to losing.

Define "losing." Europe is prematurely regarded as having lost the AI race. And yet a large portion of Europe live higher quality lives compared to their American counterparts, live longer, and don't have to worry about an elected orange unleashing brutality on them.

Europe has already lost the tech race - their cloud systems that their entire welfare states rely upon are all hosted on servers hosted by American private companies, which can turn them off with a flick of a switch if and when needed.

When the welfare state, enabled by technology, falls apart, it won't take long for European society to fall apart. Except France maybe.

I've always been fascinated to see significantly more people talking about using Claude than I see people talking about Codex. I know that's anecdotal, but it just seems Claude is often the default. I'm sure there are key differences in how they handle coding tasks and maybe Claude is even a little better in some areas. However, the note I see the most from Claude users is running out of usage. Coding differences asi…

I'm with you. Codex's plans seems to be a much more generous offering than Claude

I just.. can't tell a different in quality between them.. so I go for the cheapest

More importantly, this is the early steps of a model self improving itself. Do we still think we'll have soft take off?

Exponential growth may look like a very slow increase at first, but it's still exponential growth.

Sigmoids may look like exponential growth at first, until they saturate. Early growth alone cannot distinguish between them.

Both Opus 4.6 and GPT-5.3 one shot a Gameboy emulator for me. Guess I need a better benchmark.

As coding agents get "good enough" the next differentiator will be which one can complete a task in fewer tokens.

Or the same number of tokens in less time. Kinda feels like the CPU / modem wars of the 90s all over again - I remember those differences you felt going from a 386 -> 486 or from a 2400 -> 9600 baud modem.

We're in the 2400 baud era for coding agents and I for one look forward to the 56k era around the corner ;)

Whats interesting to me is that these gpt-5.3 and opus-4.6 are diverging philosophically and really in the same way that actual engineers and orgs have diverged philosophically With Codex (5.3), the framing is an interactive collaborator: you steer it mid-execution, stay in the loop, course-correct as it works. With Opus 4.6, the emphasis is the opposite: a more autonomous, agentic, thoughtful system that plans deepl…

> With Codex (5.3), the framing is an interactive collaborator: you steer it mid-execution, stay in the loop, course-correct as it works.

This is true, but I find that Codex thinks more than Opus. That's why 5.2 Codex was more reliable than Opus 4.5

So can I use this from Opencode? Because Anthropic started to enforce their TOS to kill the Opencode integration

You can also use via Opencode Zen, Github Copilot, or probably any number of other model providers that Opencode integrates with.

Not sure why everyone stays focused on getting it from Anthropic or OpenAI directly when there are so many places to get access to these models and many others for the same or less money.
