Flare or Sunburst?

Flare is the choice for creator and social content, product experiences, visual search, rapid prototyping and high-volume generation. Pick GPT Image 2.5 Sunburst instead when editing precision matters more than speed.

Available on AI/ML API since September 9, 2026.

Use cases

GPT Image 2.5 Flare is documented as suited to creator and social content, product experiences, visual search, rapid image prototyping, and high-volume generation. It is also described as a good choice for fast, high-quality everyday image generation.

It is documented for image generation from text prompts, including workflows that use image inputs. OpenAI also says to start with it when speed is the priority and that it is the default choice for most applications.
