# GPT-Image-2.6-All Is Live: Native GIF/SVG, 2K/4K Super-Resolution

> APIYI adds gpt-image-2.6-all on the ChatGPT web reverse route: native GIF/SVG and native ChatGPT quality up to 1536 with fingerprint. 2K/4K is a super-resolution tier for large-canvas compatibility — bigger, not necessarily more detailed. $0.025 per image; GIF dimensions remain upstream-decided.

🚀 **GPT-Image-2.6-All is live: native GIF/SVG, 2K/4K super-resolution**

`gpt-image-2.6-all` is the reverse route for ChatGPT web Images 2.6. Unlike 2.5-all, it really honors `size`, `n`, `background` and `output_format`: GIF, SVG and transparency no longer depend on prompt luck.

* **GIF / SVG**: GIF requires `output_format=gif`; frame count and duration are exact, but **`size` does not determine the GIF dimensions**. SVG is true vector, `viewBox` follows `size`, 2K–8K supported.
* **Native quality**: long edge 512–1536 is the native tier, keeping the ChatGPT web quality and fingerprint — the most controllable tier. For stable quality, stay around 1.5K.
* **2K/4K**: a **super-resolution tier** for posters, print and large screens. Common sizes such as `2048x2048`, `2048x1152`, `2048x1536` and `3840x2160` are exact; bigger does not mean more detailed. Squares cap at 2880 and 4:1 still returns 400.
* **Formats**: PNG / JPEG / GIF / SVG. Transparent output works up to 2K; WebP is not supported.
* **Price**: \$0.025 per image; 2K/4K costs the same.
* **Limits**: 2K/4K responses may omit `size`; 9:16 occasionally returns 1365x2048 and 4K occasionally 4096x2731. 4K transparency is unstable and `quality=low` may return 2048x1153 at 2K. **Always verify the actual image dimensions.**
