Has LLM progress slowed? Initial reactions to GPT-5 were mixed: to many, it did not seem as dramatic an advance as GPT-4. Benchmarks may help clarify the picture: GPT-5 is both an incremental release following many other OpenAI advances, and a major leap from GPT-4. https://x.com/EpochAIResearch/status/1961524635398529209

This is disappointing. Purposefully underselling what models can do is a really bad idea. It is possible to point out that AI is flawed without saying it can’t do math or count – it just isn’t true.

GPT-5 Pro and Gemini 2.5 Pro Deep Think are both very impressive models for hard problems.

I think this is an accurate take: the leap from GPT-4 to GPT-5 was as big as the leap from the original GPT-3 to GPT-4, but there were many more interim releases before GPT-5 (including o3). Each of these led to gains, so that the progress from them to GPT-5 was more incremental. https://x.com/emollick/status/1961561611291779231

Alex – I’m excited to announce that we’re joining OpenAI’s Codex team! When we started out, Xcode had no AI. Building a “Cursor for Xcode” sounded crazy, but we managed to do it anyway.

@jeremyphoward Fixing this is very high on the priority list for the next version! The reason it says it in the system prompt is because the model was asking too many clarification questions (and thinking long for each) which IMO was even worse UX.”” / X https://x.com/yanndubs/status/1961716590568706226

GPT-OSS uses MXFP4 quantization (which MLX now supports). There are two FP4 formats circulating right now: MXFP4 and NVFP4 (NV for Nvidia).
