# GPT-Image 2.5-All and 2-All now support size targets

> gpt-image-2.5-all and gpt-image-2-all now accept size as the priority target. Omit it or use auto for native behavior, with prompt-based size and ratio descriptions still available. The guide includes supported targets, interpolation notes, and a request example.

🚀 **`gpt-image-2.5-all` and `gpt-image-2-all` now support `size`.**

An explicit `size`, such as `1024x1024`, is the priority target. Omit it or pass `auto` to preserve native behavior; prompts can still describe dimensions and aspect ratios.

Common `WxH` targets with a long edge of 512–1536 pixels are supported, including dimensions that are not multiples of 16. A 1536 square may involve interpolation. 2K sizes are not currently listed as precisely supported; verify actual image dimensions for strict requirements.

[See the size table and request example](https://docs.apiyi.com/en/api-capabilities/gpt-image-2-all/overview.md).
