<Tip>To use Letta with Together.AI, set the environment variable `TOGETHER_API_KEY=...`</Tip>

You can use Letta with Together.AI if you have an account and API key. Once you have set your `TOGETHER_API_KEY` in your environment variables, you can select what model and configure the context window size.

## Enabling Together.AI as a provider
To enable the Together.AI provider, you must set the `TOGETHER_API_KEY` environment variable. When this is set, Letta will use available LLM models running on Together.AI.

### Using the `docker run` server with Together.AI
To enable Together.AI models, simply set your `TOGETHER_API_KEY` as an environment variable:
```bash
# replace `~/.letta/.persist/pgdata` with wherever you want to store your agent data
docker run \
  -v ~/.letta/.persist/pgdata:/var/lib/postgresql/data \
  -p 8283:8283 \
  -e TOGETHER_API_KEY="your_together_api_key" \
  letta/letta:latest
```
