Seed-2.0-Mini
VerifiedEfficient multimodal model for long-context text, image, and video tasks.
About Seed-2.0-Mini
Seed-2.0-Mini employs a unified architecture that ingests and reasons over mixed text, image, and video inputs. Its large context capacity supports extended sequences such as full-length videos paired with detailed instructions or documents. The compact design balances capability with deployment efficiency while remaining proprietary.
Typical applications include video analysis, image captioning with narrative context, and multi-turn multimodal conversations. Developers integrate it into content platforms, creative tools, and enterprise systems requiring synchronized understanding of visual and textual data.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "bytedance-seed/seed-2.0-mini",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: bytedance-seed/seed-2.0-mini
