# Capabilities

> Key GeneralCompute features: tool calling, JSON mode, and reasoning-ready models.

## OpenAI-compatible surface

Every GeneralCompute endpoint mirrors the OpenAI API shape (`chat.completions`, `models`, etc.). Use any existing OpenAI SDK or the official `@generalcompute/sdk` / `generalcompute` packages — no request body changes required.

## Tool calling & JSON mode

Function and tool calling are fully supported. Define tools exactly as you would with OpenAI and inspect the returned `tool_calls` array to decide which function to execute.

```typescript theme={null}
const completion = await client.chat.completions.create({
  model: "deepseek-v3.2",
  messages,
  tools: [
    {
      type: "function",
      function: {
        name: "get_weather",
        description: "Look up the weather for a city",
        parameters: {
          type: "object",
          properties: { location: { type: "string" } },
          required: ["location"],
        },
      },
    },
  ],
  response_format: { type: "json_object" }, // JSON mode
});
```

> Tool calls stream through the same delta events you receive from OpenAI, so orchestrators such as LangChain, Vercel AI SDK, and LlamaIndex work out of the box.

## Reasoning models

Reasoning-first models (`deepseek-v3.2`, `deepseek-v3.1`) are deployed with higher thinking timeouts. Use them when you need chain-of-thought quality:

```typescript theme={null}
const completion = await client.chat.completions.create({
  model: "deepseek-v3.2",
  messages,
  temperature: 0.1,
  max_completion_tokens: 2048,
});
```

Combine reasoning with tool calling to build autonomous agents without changing your orchestrator code.
