# Other LLMs

Aider uses the [litellm](https://docs.litellm.ai/docs/providers) package
to connect to hundreds of other models.
You can use `aider --model <model-name>` to use any supported model.

To explore the list of supported models you can run `aider --models <model-name>`
with a partial model name.
If the supplied name is not an exact match for a known model, aider will
return a list of possible matching models.
For example:

```
$ aider --models turbo

Aider v0.29.3-dev
Models which match "turbo":
- gpt-4-turbo-preview (openai/gpt-4-turbo-preview)
- gpt-4-turbo (openai/gpt-4-turbo)
- gpt-4-turbo-2024-04-09 (openai/gpt-4-turbo-2024-04-09)
- gpt-3.5-turbo (openai/gpt-3.5-turbo)
- ...
```

See the [model warnings](warnings.html)
section for information on warnings which will occur
when working with models that aider is not familiar with.

## LiteLLM

Aider uses the LiteLLM package to connect to LLM providers.
The [LiteLLM provider docs](https://docs.litellm.ai/docs/providers)
contain more detail on all the supported providers,
their models and any required environment variables.
