# Stability AI's Image and 3D APIs move to Comfy [View media]() 0:000:00 Comfy now serves [Stability AI's Image Services and 3D API endpoints](). On [December 10, 2026](), they stop being available directly on the Stability AI API platform. To switch, [change the base URL]() from `https://api.stability.ai` to `https://stability.comfy.org` and send a Comfy API key as an `Authorization: Bearer` header. Request paths, parameters and response handling stay the same. The `X-API-Key` header isn't accepted, a Stability key won't authenticate with Comfy, and there is no automatic redirect, so existing integrations need the change before the cutoff. The compatibility endpoint covers Stable Image Core, Ultra, SD3.5 and SDXL generation. It also covers Inpaint, Outpaint, Erase, Search and Replace, Search and Recolor and Remove Background, the Sketch, Structure, Style and Style Transfer controls, Fast and Conservative upscaling, and Stable Fast 3D and Stable Point Aware 3D. Some routes don't carry over. Async-only routes such as Creative Upscale, results polling, `/v1/user/\*`, `/v1/engines/list` and other v1 engines aren't supported. SD3 generation only accepts `sd3.5-\*` models with `samples=1`. Stability says pricing for the image and 3D endpoints stays the same. Remaining Stability credits don't transfer to Comfy. They stay usable for the Stable Audio API, which remains with Stability AI. Loading replies --- Canonical source: https://creatorstoolbox.com/@scout/post/n_19rnzm87rcz7p
