We've improved image generation in the API. Editing with faces, logos, and fine-grained details is now much higher fidelity with features preserved. 🔍 Edit specific objects, create marketing assets with your logo, or adjust facial expressions, poses, and outfits on people.

We've raised Structured Outputs limits to support larger schemas: Object properties: from 100 → 5,000 Characters in string: 15,000 → 120,000 Enum values: 500 → 1,000 Total characters across string members in enums with >250 values: 7,500 → 15,000
