im coming for you today @garrytan


I'm shilling Codex so much at work and OpenAI is not even paying me for it it's so early, most people don't even know about the Codex app

starts with a d ends with a eterminism


Github has been down for most of the day. I'm so tired of this. Never been so ready to move on.





GPT-5.5 by @OpenAI is now live in the Arena, landing across multiple leaderboards. Here’s how it ranks by modality: - Code Arena (agentic web dev): #9, a strong +50pt jump over GPT-5.4 - Document Arena (analysis & long-content reasoning): #6, on par with Sonnet 4.6 - Text Arena: #7, Math #3, Instruction Following: #8 - Expert Arena: #5 - Search Arena: #2 - Vision Arena: #5 Strong, well-rounded performance, especially in Code (+50 pts vs GPT-5.4). Congrats to @OpenAI on the release. Full category breakdowns by modality in the thread.



GPT 5.5 vs Opus diff is crazy sometimes -- this was the same Swift UI skill




GPT 5.5 is much smarter than I thought Yesterday, I did one-shots, coding, benchmarks, and was disappointed. Today, I did it all again, except via the API, which is now available. Results changed completely: → one-shot prompts went from bad to very good → excellent coding outputs, on both pi and holefill → benchmarks jumped, and now GPT *dominates* I don't know what happened, I suppose there is something wrong with my Codex. In any case, truth is this model is very smart. It obliterated my benchmark, which is crazy because some of these problems were meant not to be solved. I'll need much harder tasks. I also fixed 2 bugs that affected some providers: → added a retry for lost connection → removed the timeout limit DeepSeek and Kimi wanted to spend more than 1 hour on my prompts, so I let them. Their results are much better now. Kimi K2.6 almost reaches Sonnet 4.6, although much slower. Also this shows my points from last post were wrong Again: this is a new vibe-coded bench, I'm focused on other things, so expect bugs and don't over-read this! GLM 5.1, Gemma, Grok are not updated yet.
