# Fireworks

> Fireworks AI delivers fast open-source model inference with integrated fine-tuning capabilities, allowing teams to both deploy and customize models through the same platform.

Fireworks offers 20 models through Lava's AI Gateway, supporting Chat Completions. Authentication uses `Authorization: Bearer`. See the [Fireworks API docs](https://docs.fireworks.ai/api-reference) for provider-specific parameters.

<Info>Supports both **managed** (Lava's API keys) and **unmanaged** (bring your own credentials) mode.</Info>

## Quick Start

```typescript theme={null}
const response = await fetch('https://api.lava.so/v1/forward?u=https%3A%2F%2Fapi.fireworks.ai%2Finference%2Fv1%2Fchat%2Fcompletions', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    Authorization: `Bearer ${forwardToken}`,
  },
  body: JSON.stringify({
    model: 'accounts/fireworks/models/kimi-k2-instruct',
    messages: [{ role: "user", content: "Hello!" }],
  }),
});
```
