Access 4 Deep Infra models through Mastra's model router. Authentication is handled automatically using the DEEPINFRA_API_KEY environment variable.

Learn more in the Deep Infra documentation.

DEEPINFRA_API_KEY=your-api-key
import { Agent } from "@mastra/core";

const agent = new Agent({
  name: "my-agent",
  instructions: "You are a helpful assistant",
  model: "deepinfra/Qwen/Qwen3-Coder-480B-A35B-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);
}
OpenAI Compatibility

Mastra uses the OpenAI-compatible /chat/completions endpoint. Some provider-specific features may not be available. Check the Deep Infra documentation for details.
