OpenAI launches ChatGPT Images 2.5 and two API models: GPT-Image-2.5 Flare, fast for everyday use, and GPT-Image-2.5 Sunburst, more precise for detailed editing. ### What changes - Generation latency reduced by up to 50% compared with Images 2.0. - Better fidelity to reference photos, targeted editing and consistency across several editing turns. - Transparent backgrounds and more complex layouts. - In ChatGPT: Sketch (drawing as a guide), starter templates, comments on the image and prompt sharing. - Traceability through C2PA metadata and an invisible watermark. ### Specifications - Text and image input, image output. Qualities: low, medium, high, xhigh, max and auto. - Availability: ChatGPT, ChatGPT Work and Codex (all plans); Images API and the image generation tool of Responses. - Sunburst: maximum precision for editing, longer durations; Flare: the fastest. - Identifiers: gpt-image-2.5-sunburst, gpt-image-2.5-flare. ### Pricing | Modality | Input | Cached input | Output | | --- | --- | --- | --- | | Image | $8.00 | $2.00 | $30.00 | | Text | $5.00 | $1.25 | n/a | Price per million tokens (USD), identical for both models and in line with GPT Image 2. ### Benchmarks No numerical score published by the vendor in the announcement. ### Key takeaways The pricing remains that of GPT Image 2: the choice between Flare and Sunburst comes down to speed versus editing precision. The GPT Image 2 cost calculator does not cover the token consumption of version 2.5.
