TensorX

Access 25 TensorX models through Mastra's model router. Authentication is handled automatically using the TENSORX_API_KEY environment variable.

Learn more in the TensorX documentation.

.env

TENSORX_API_KEY=your-api-key

src/mastra/agents/my-agent.ts

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

const agent = new Agent({
  id: "my-agent",
  name: "My Agent",
  instructions: "You are a helpful assistant",
  model: "tensorx/deepseek/deepseek-r1-0528"
});

// 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);
}

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