Seed-2.0-Lite API on ModelFold
Seed-2.0-Lite is a versatile, cost-efficient enterprise workhorse from ByteDance Seed, with strong multimodal and agent capabilities and noticeably lower latency, making it a practical default for most production workloads. Try Seed-2.0-Lite in the ModelFold Playground, then call it from your own code through an OpenAI-compatible chat completions API.
What Is the Seed-2.0-Lite API
Seed-2.0-Lite at a glance
Seed-2.0-Lite is a chat model from ByteDance. It accepts text, images and video as input and returns text, with a context window of up to 262K tokens.
Use it without hosting anything
On ModelFold you call Seed-2.0-Lite with a single API key — no model weights to download and no inference servers to run. The same key also works for the other chat, image, video and audio models on ModelFold.
Core Capabilities of Seed-2.0-Lite
Up to 262K tokens of context
Keep long conversations, large documents and sizeable code in a single request, so the model can reason over the full material instead of fragments.
Understands images and video
Besides text, Seed-2.0-Lite accepts images and video as input, so a single request can combine instructions with visual or other media.
Function calling
Seed-2.0-Lite supports tool (function) calling: describe your functions in the request and the model returns structured calls your code can run — the basis for agents and integrations.
Adjustable reasoning effort
Choose a reasoning effort level (low, medium or high) per request to balance depth of thinking against speed and token usage.
Structured outputs
Ask for JSON that follows a schema (response_format), which makes extraction, classification and system integrations more reliable.
