I live-blogged the keynote here, adding a little bit of extra commentary and links along the way: https://simonwillison.net/2025/Oct/6/openai-devday-live-blog/ https://simonwillison.net/2025/Oct/6/openai-devday-live-blog...

  "Sam says today Codex is out of preview and into GA. But which one! Codex CLI or Codex Cloud or both?" The cloud version as "Starting October 20, Codex cloud tasks will also begin counting towards your Codex usage"

  Reading through this was so cool! What was being in-person at the keynote like, overall?

The "live" coding demo felt very staged with codex reasoning set at "low" and everything working ootb.

  Probably didn't want to risk the same embarrassment that was the Meta live demo.

    Every single person I know had nothing but respect for the meta people doing it live. I think they garnered more attention that way

      We clearly don't have the same friends then! The event was the ridicule of the day on Twitter (wrongly, in my opinion, given that the tech is very good).

I created transcript for it for anyone wanting to read instead of listen! https://videotobe.com/play/youtube/hS1YqcewH0c https://videotobe.com/play/youtube/hS1YqcewH0c

I follow things pretty closely, and I was genuinely unsure if GPT5-pro was a real thing or just equivalent to setting GPT-5 to high reasoning. Does the fact it's entering the API confirm that it's a fully separate thing which is not widely benchmarked, and which was not part of the GPT-5 stream? This particular thing has not been well communicated AFAICT.

  GPT-5 Pro is not just GPT-5 with higher reasoning effort - it’s a different thing. Under the hood, it’s based on GPT-5, and you’ll notice all of GPT-5’s personality traits in its outputs, so it still bears the GPT-5 brand.

  GPT-5 Pro is different from GPT-5 just like o3 Pro is different from o3 and o1 Pro is different from o1 :) OpenAI doesn't want to tell the truth, but it might be something similar in the spirit to e.g. Entropix. [0] [0] https://github.com/xjdr-alt/entropix https://github.com/xjdr-alt/entropix
