Access 72 SiliconFlow models through Mastra's model router. Authentication is handled automatically using the SILICONFLOW_API_KEY environment variable.

Learn more in the SiliconFlow documentation.

import { Agent } from "@mastra/core/agent";

const agent = new Agent({
  id: "my-agent",
  name: "My Agent",
  instructions: "You are a helpful assistant",
  model: "siliconflow/ByteDance-Seed/Seed-OSS-36B-Instruct"
});

// Generate a response
const response = await agent.generate("Hello!");

// Stream a response
const stream = await agent.stream("Tell me a story");
for await (const chunk of stream) {
  console.log(chunk);
}
