GPT-5.2 disappeared from ChatGPT without advance notice, despite Aug 10 shutdown date in deprecations docs

Olesia: > but a broader Plus rollout/access problem Yes, it could totally be it and given that they just made changes when it comes to ChatGPT model picker, there’s always a risk that there might be some temporary glitches. This could be one of them. There is a thread where users can’t pick intelligence for the model, so this could be related to it. But instead of me speculating on what it could and couldn’t be, it was right thing to contact the support. Hopefully this gets sorted for you, so you can continue to use 5.2 for a while at least. Small recommendation though, personally I think 5.5 is probably closest to 5.2 and if you haven´t, maybe give it a shot?
