GPT‑5.5 Instant

GPT-5.3-instant wasn't even close to instant. Even with lowest effort it's like 3-4x best case TTFT compared to GPT-4.1

I know, I know.. But they are the one's labeling them "instant". There is a real need for a refresh on the datacenter workhorse that is GPT-4.1

Also, how TF are you going to have an "instant" model release and not mention the latency characteristics at all?

Is this available on the API? I didn't see instant. I see chat?

Why can't they be more consistent about releasing the Insant and Thinking models at the same time for each version number? Why all this duplicative drama?

Big increase in intelligence at the cheapest price

I wonder what's the difference between this and GPT 5.5 thinking with zero thinking effort? Interesting product decision to have different models.

Looks like it gives more readable answer, hopefully it does, the regular free ChatGPT modal right now is insufferable.

Nice, something actually usable and at an affordable price.
