GPT Image 2 is OpenAI's current image generation and editing model for fast, high-quality image creation, with flexible image sizes and high-fidelity image inputs through the OpenAI Images API.
GPT Image 2.5 Sunburst is one of two API variants OpenAI released alongside ChatGPT Images 2.5 (September 2026), built for workflows where editing precision matters most.
On ImageBench V1 (192 prompts, 6 categories), GPT Image 2 scores 80 overall with a 87% task pass rate, while GPT Image 2.5 Sunburst scores 82.1 overall with a 88% pass rate. The biggest difference is spatial reasoning: GPT Image 2 passes 91.2% of those prompts vs 98.2% for GPT Image 2.5 Sunburst. GPT Image 2 is an API model (token-based); GPT Image 2.5 Sunburst is an API model (token-based).
GPT Image 2.5 Sunburst is better overall on ImageBench V1, scoring 82.1 vs 80. GPT Image 2 is strongest at text rendering (100%). GPT Image 2.5 Sunburst is strongest at text rendering (100%).
Yes — on the Spatial Reasoning category of ImageBench V1, GPT Image 2 passes 91.2% of prompts and GPT Image 2.5 Sunburst passes 98.2%. That is the largest per-category difference between GPT Image 2 and GPT Image 2.5 Sunburst.
