Image editing limitations
- The edit model (gpt-image-1) changes backgrounds and scene elements but cannot guarantee exact facial preservation - faces may shift slightly
- HEIC files must be converted before editing
- Very complex edits ("put this person in a completely different scene") work better than subtle edits ("adjust the lighting slightly")
