# Leaderboard # - Highest Tokens Generated in Response

Hey why not, for fun…

What’s the highest token count you’ve gotten in response from a GPT model, whether reasoning or non?

I just got 13k tokens as a single code file (py)! As a part of a 16.5k total response.

So… stats and a little bit of context?


GPT-5 : 16k total tokens

Med Reas : High Verbosity : /chat/completions

(prompt 116k total 133k) , 4m15s time to completion


Context: Surprising most to me was the successful generation of a single code file of the length and complexity that was achieved. It was a re-write/overwrite of an existing file containing mostly similar content but with significant re-factoring.

Note: Since I wasn’t using /responses, I didn’t get feedback on “reasoning tokens” or whatever. This was a single-shot in the sense that there was no “internal” tool calling or whatever - this was just a straight single generation from chat completions.

How long for it to respond, what settings, any context beyond a simple prompt?

That was mostly the AI repeating back more of my code base than the refactor task required. Sept 13.
