OpenAI ships ChatGPT Images 2.5 with 50% lower generation latency
OpenAI released ChatGPT Images 2.5 five months after Images 2, cutting generation latency by up to 50% and adding Sketch for drawing references, format templates, and prompt sharing. Two API models ship alongside it — GPT-Image-2.5 Flare as the default and Sunburst for tighter control across edits — so developers building visual products now pick between throughput and edit fidelity rather than settling for one image model. The speed gain is the concrete change; the rest is packaging around an incremental quality bump.

We've also reduced image generation latency by up to 50% compared with Images 2.0, so you can generate images and refine your concepts more quickly.

Why this matters
- → 50% latency cut makes real-time image workflows viable at scale.
- → Dual API models let developers trade speed for edit precision instead of accepting tradeoffs.
- → Sharper details + better lighting close the gap to custom visual content.
Speed meets control
