Any previewers have hot takes? I've really preferred gpt-5.5 over Opus 4.8 for data analysis and scientific software work. It seems much more reliable. Fable is unusable for the type of work that I do (due to guardrails). Really looking forward to trying these new OpenAI models out.

It seems comparable to Fable to me in my uses.

  That's great to hear - and for the same price as 5.5, and reportedly with much lower token use per task. Were you able to try Sol Ultra?

    No, my organization limits access to xhigh.

  What types of use cases?

Interesting to hear people like gpt-5.5. For me it feels smart only at one shot prompts, but if you try to build up session context before doing something it feels magnitudes inferior to Claude. I'm almost sure its because the thinking of previous turns is stripped with the responses API, so if I tell it to analyse something deeply, what remains of the understanding in future turns is only the short response text of that analysis

  For gpt-5.5 I build up that session context into a markdown file, and then I start a new session and give it the markdown file with the instructions for what to do. I'm guessing this works better because it can always go back and re-analyze the saved context.

  > thinking of previous turns is stripped with the responses API Why do they store an encrypted reasoning payload in the session file and pass it to the API? Just a ruse? Reasoning isn’t even that many tokens, you think they’d degrade their model quality like that? Reasoning messages would be lost immediately after a single tool call, unless you mean they sometimes go back and strip the reasoning channel retroactively, but that would increase costs via cache invalidation. I just don’t see any way it would make sense for them to do. And wouldn’t this be noticeable by reasoning tokens not being accounted for in the context window usage?

  Do you have a source for this? I'm pretty sure responses api is only there to obfuscate reasoning, but that they're still keeping reasoning traces in the backend.

      Well, obviously its true as you can see in the silbing comment. But still interesting how experiences differ. I wonder did you ever use codex in more demanding workflows, because that at least something like that is going on is obvious if you use it for a few hours

      Looks like you're wrong, if you look at the sibling

      You answered at more or less the same time as an OpenAI engineer confirming this is the case, explaining why they did it, and pointing to their docs that also very explicitly explain this "made-up nonsense". You should really consider why you felt so certain about something you were plain wrong about.

        Exactly, it's ironic that they thought they were right while talking about not having sources for another comment.

For compiler work I found that Sol is noticably better than 5.5 (and I generally use OAI models because I like the Codex app), but Fable was still obviously better.

  Better in what way? Does it follow the goals better, does the code produce have higher quality in a testable/maintainable sense or is it just closer to how you would usually program something?

Interesting, data analysis work is the only thing I’ll use Gemini for

I'm sorry to hear you are unable to use Fable; my partner is in the same boat and it frustrates her immensely to see what I've been able to do with it. As someone who is working with developing new linear algebra routines, Fable is so far ahead of GPT-5.5 and Opus that it's obscene. Massively better insights and far better at handling delicate corner cases without needing to mention them. I would be stunned if GPT-5.6 is at that level, but one can hope.
