Description

ByteDance Doubao Seed 2.1 Turbo — the low-latency lane of the Seed 2.1 line, sharing Pro's envelope: 256K context window with 256K maximum input, up to 256K output tokens (4K by default), and a 256K chain-of-thought budget. Covers deep thinking, text generation, multimodal understanding, tool calling, and structured output, though without Pro's json_schema recommendation. Accepts text, image, and video and returns text; audio understanding is not listed for the 2.1 line. Supports implicit and explicit context caching.
