GPT Image 2.5
OpenAI's current image models — Sunburst for quality, Flare for fast everyday generation
Verdict
OpenAI's image line has moved quickly: GPT Image 1 relaunched ChatGPT image generation in 2025, GPT Image 2 followed in April 2026, and GPT Image 2.5 arrived in September 2026 in two variants, Sunburst (the most capable) and Flare (fast, everyday generation). Native multimodal generation (the same model reasons about text and pixels together) is what gives the line its instruction-following, in-context editing, and text rendering. Default choice for API-accessible image gen; GPT Image 1 is still served but there is no reason to start on it.
