I doubt so, specially find it quite hard to reconcile with how teams at OpenAI have been pushing GPTs to the extreme for exact same tasks mentioned above! That said, I’d be keen to look at examples where other coding agents perform better at tasks which codex doesn’t

Let me explain again. My argument is this: Lecun says, verbatim: "He knows absolutely nothing about the effects of technological revolutions on the labor market. Don't listen to him, Sam, Yoshua, Geoff, or me on this topic. Listen to economists who have spent their career

GPT-5.4 Pro Test Model Shows Enhanced Capabilities

I don’t think the model currently being tested in GPT-5.4 Pro is GPT-5.5 Pro.

That said, it does feel noticeably more capable while also being cheaper to run. However, rather than a direct successor to 5.4 Pro, it seems closer to a different class of model—something more in line… https://t.co/OYfS7vs5bcI don’t think the model currently being tested in GPT-5.4 Pro is GPT-5.5 Pro.

Pro model in ChatGPT does feel very different – the generations are a lot faster (20 mins vs 60-80 mins for Pro Extended) and the quality is really excellent.

I'll do a side by side later, but this golden gate is quite excellent vs what all other models can do in one shot. https://t.co/LnIYY9jUC7 pic.twitter.com/drXuztL7oZPro model in ChatGPT does feel very different – the generations are a lot faster (20 mins vs 60-80 mins for Pro Extended) and the quality is really excellent.

Some people say that GPT-5.5 is already rolling out for them, it’s being stealth tested. Initial testing from them say it outperforms Opus4.7 for them (don’t know in which tasks tho). Hopefully it’s not being released on Monday since I’ll be on a 13hour flight to china and would

Fill-in-the-middle completion used by old code models like GitHub Copilot
By

Fill-in-the-middle completion was the closest variant of this idea that was ever widely used AFAIK. Old code models (e.g. the original GitHub Copilot) depended on that.
