# List Models

The `list_models` and `alist_models` functions return the available models for a given provider.

### `any_llm.list_models()`

```
def list_models(
    provider: str | LLMProvider,
    api_key: str | None = None,
    api_base: str | None = None,
    client_args: dict[str, Any] | None = None,
    **kwargs: Any,
) -> Sequence[Model]
```

### `any_llm.alist_models()`

Async variant with the same parameters.

```
async def alist_models(
    provider: str | LLMProvider,
    api_key: str | None = None,
    api_base: str | None = None,
    client_args: dict[str, Any] | None = None,
    **kwargs: Any,
) -> Sequence[Model]
```

### Parameters

| Parameter     | Type                     | Default    | Description |
| ------------- | ------------------------ | ---------- | ----------- |
| `provider`    | `str \| LLMProvider`     | *required* |             |
| `api_key`     | `str \| None`            | None       |             |
| `api_base`    | `str \| None`            | None       |             |
| `client_args` | `dict[str, Any] \| None` | None       |             |
| `**kwargs`    | `Any`                    | *required* |             |

### Return Value

Returns a `Sequence` of [`Model`](/api-reference/completion-1/model.md) objects. Each `Model` has at minimum an `id` field containing the model identifier string.

### Usage

```python
from any_llm import list_models

models = list_models("openai")
for model in models:
    print(model.id)
```

#### Async

```python
import asyncio
from any_llm import alist_models

async def main():
    models = await alist_models("mistral")
    for model in models:
        print(model.id)

asyncio.run(main())
```

#### Using the AnyLLM class

```python
from any_llm import AnyLLM

llm = AnyLLM.create("openai")
models = llm.list_models()
print(f"Available models: {len(models)}")
```

{% hint style="info" %}
Not all providers support listing models. Check the [providers page](/providers.md) for support details, or query `ProviderMetadata.list_models` programmatically.
{% endhint %}
