What ByteDance Seed: Seed-2.0-Mini can do.

Reasoning

Extended reasoning

Multimodal

Image understanding

Reads and reasons over images alongside text in the same prompt.

Video input

Takes video as an input modality alongside text and images.

Development

Tool calling

Calls external functions mid-response, then continues reasoning from the result.

Structured output

Streaming
