One of the surprises for me from the GPT-5 launch yesterday is how OpenAI removed access to older models (like GPT-4o) for most ChatGPT users at the same time as they rolled out the new model. I wrote about how that's been playing out here: https://simonwillison.net/2025/Aug/8/surprise-deprecation-of-gpt-4o/

Here's a good TikTok from @cfiesler@hci.social about the emotional impact the loss of GPT-4o is having on some of its users https://www.tiktok.com/@professorcasey/video/7536223372485709086

Sam Altman just announced a change in policy, GPT-4o will be coming back, at least for Plus ($20/month) users https://x.com/sama/status/1953893841381273969

@simon@fedi.simonwillison.net people still link to x dot com?

@codinghorror@infosec.exchange a bunch of the AI labs have the infuriating habit of posting announcements there and nowhere else - OpenAI are particularly bad for this, but I've seen it from Qwen and Anthropic and others as well

(This might be because every time they try to post things to Bluesky or Mastodon they get something of a crowd with pitchforks vibe in response)

@simon@fedi.simonwillison.net @codinghorror@infosec.exchange not just labs, the whole AI crowd is predominantly there. It's the main reason I still keep an eye on it.

@goncalossilva@fosstodon.org @simon@fedi.simonwillison.net now is a good time to remember that screenshots exist.
