Like others, I ran into an issue a few months ago, where I ran up against a character limit for the description of a function schema. You’re limited to 1024 characters in the description field for the function.
However while experimenting today with my schema, that limit no longer seems to be in place. Was this announced somewhere and I missed it?
depends on the model, if you are using the standard it could’ve have been, kinda hard to know for use without specifics, but I’d suggest checking out the documentation on the specific model and seeing if anything has changed around there
There is no documentation on specific models.
It looks like the tool description (on Responses) is only limited by nearly the model’s context length.
Sending two unjoinable tokens x 62000 to gpt-4o is successful, while 63000=126000 is “500 An error occurred while processing your request” regardless of max_output_tokens or not (and not a context exceeded message).
Hyphens, with dozens of characters per token took forever, but…
- Testing model 'gpt-4o' with description length: 500000 chars.
- Success for model 'gpt-4o' (no error raised)
