GPT Image 1.5 Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for GPT Image 1.5, so this page shows no scores. We do not publish numbers we have not measured.
GPT Image 1.5 Limitations
- Token usage makes the exact upstream cost variable
