Why would some one use codex instead?

I've been using Codex for software development personally (I have a ChatGPT account), and I use Claude at work (since it is provided by my employer). I find both Codex and Claude Opus perform at a similar level, and in some ways I actually prefer Codex (I keep hitting quota limits in Opus and have to revert back to Sonnet). If your question is related to morality (the thing about US politics, DoD contract and so on).…

Exact same situation here. I've been using both extensively for the last month or so, but still don't really feel either of them is much better or worse. But I have not done large complex features with it yet, mostly just iterative work or small features.

I also feel I am probably being very (overly?) specific in my prompts compared to how other people around me use these agents, so maybe that 'masks' things

in my testing codex actually planned worse than claude but coded better once the plan is set, and faster. it is also excellent to cross check claude's work, always finding great weakness each time.

That’s why I think the sweet spot is to write up plans with Claude and then execute them with Codex

I am very curious about this:

> Theme park simulation game made with GPT‑5.4 from a single lightly specified prompt, using Playwright Interactive for browser playtesting and image generation for the isometric asset set.

Is "Playwright Interactive" a skill that takes screenshots in a tight loop with code changes, or is there more to it?

What a model mess! OpenAI now has three price points: GPT 5.1, GPT 5.2 and now GPT 5.4. There version numbers jump across different model lines with codex at 5.3, what they now call instant also at 5.3. Anthropic are really the only ones who managed to get this under control: Three models, priced at three different levels. New models are immediately available everywhere. Google essentially only has Preview models! Th…

I guess that's true, but geared towards API users.

Personally, since "Pro Mode" became available, I've been on the plan that enables that, and it's one price point and I get access to everything, including enough usage for codex that someone who spends a lot of time programming, never manage to hit any usage limits although I've gotten close once to the new (temporary) Spark limits.

Anyone else getting artifacts when using this model in Cursor? numerusformassistant to=functions.ReadFile մեկնաբանություն 天天爱彩票网站json {"path":

I've seen that problem with 5.3-codex too, it didn't happen with earlier models.

Looks like some kind of encoding misalignment bug. What you're seeing is their Harmony output format (what the model actually creates). The Thai/Chinese characters are special tokens apparently being mismapped to Unicode. Their servers are supposed to notice these sequences and translate them back to API JSON but it isn't happening reliably.

Haha. This was the second time in like a year that I’ve posted a Twitter link, and the second time someone complained. Okay, I’ll try to remove those before posting, and I’ll edit this one out. Feels like a losing battle, but hey, the audience is usually right.

I'm sorry, but it's my pet peeve. If you're on iOS/macOS I built a 100% free and privacy-friendly app to get rid of tracking parameters from hundreds of different websites, not just X/Twitter. https://apps.apple.com/us/app/clean-links-qr-code-reader/id6...

This is great! I have been meaning to implement this sort of thing in my existing Shortcuts flow but I see you already support it in Shortcuts! Thank you for this!

Anywhere I can toss a Tip for this free app?

The "RPG Game" example on the blogpost is one of the most impressive demo's of autonomous engineering I've seen. It's very similar to "Battle Brothers", and the fact that RPG games require art assets, AI for enemy moves, and a host of other logical systems makes it all the more impressive.

I don't know. It looks shallow and simple, not even a demo.

> Google essentially only has Preview models! The last GA is 2.5. As a developer, I can either use an outdated model or have zero insurances that the model doesn't get discontinued within weeks. What's funny is that there is this common meme at Google: you can either use the old, unmaintained tool that's used everywhere, or the new beta tools that doesn't quite do what you want.
