Error when attempting to access gpt-image-1.5 in images/edits
OpenAI Developer Community
March 3, 2026
The docs for “edits” simply “never said” what was needed at all - the prior set of parameters is still around, and it is easy to make a mistaken assumption that if you want ‘b64’ you still might ask for it. Missing:
_j:
Unsupported for
gpt-image-1.
Then, if you are forced to infer parameter usage from the “generations” docs, you might also wonder why “quality” of gpt-image models doesn’t work on the edits API, either.
Here’s the “edits” API documentation with “response_format” that was wiped, instead of properly modified with notations.
