OpenAI launches ChatGPT Images 2.5 with two models and sharper editing

OpenAI 发布 ChatGPT Images 2.5 双图像模型，主打更快生成与局部编辑

OpenAI released ChatGPT Images 2.5 with two models: Flare for speed (up to 50% lower latency) and Sunburst for tighter editing control at longer generation times. API pricing is $8/1M input tokens and $30/1M output tokens. New 'xhigh' and 'max' quality tiers push a 1024x1024 max image to roughly $0.21. No batch pricing is offered yet, and OpenAI didn't share an average per-image cost. ChatGPT users can't manually pick the model; the post's tests show Work mode keeps edits more stable than Chat mode. Both models top the image arena rankings, and watermarking is added in partnership with Google DeepMind.

Why it matters: Substantive image-gen upgrade from OpenAI with clear dual-model split and concrete performance/pricing numbers. But it's an iteration, not a paradigm shift, and Plus users can't access Sunburst yet — that caps the score.
