Remove Background

Model ID

Use with the Workers AI binding, the AI Gateway REST API, or the Unified API.

Calling the provider directly? Use the provider's model name instead, including with provider-native endpoints or the provider's own SDK. For example, Anthropic's name for anthropic/claude-opus-4.8 is claude-opus-4-8.

Third-party

Bria's RMBG 2.0 model removes the background from an image and returns a PNG cutout with a transparent background. Partial transparency from the input's alpha channel is kept by default.
