Seed 2.1 Turbo accepts text, image, and video as listed input formats. Listed output formats include text. Image or audio input support does not imply image or audio generation. Check the chosen provider’s Seed 2.1 Turbo documentation for supported file types and request formats.
Seed 2.1 Turbo has a listed context window of 262K tokens. Tokens are small pieces of content rather than a word count. Instructions, conversation history, and other inputs use context space, and the response also needs room. The maximum output length for Seed 2.1 Turbo may be smaller than the context window and can vary by provider.
Seed 2.1 Turbo has both reasoning and tool calling listed as supported capabilities. Reasoning enables additional processing for complex problems. Tool calling allows a model to request functions that your app executes. Check the chosen provider’s documentation for capability availability and setup.
