## Overview

Model information endpoints

### Available Operations

* [get](#get) - Get a model by its slug
* [list](#list) - List all models and their properties
* [count](#count) - Get total count of available models
* [list_for_user](#list_for_user) - List models filtered by user provider preferences, privacy settings, and guardrails

## get

Returns full details for a single model identified by its author and slug (e.g. openai/gpt-4). Supports variant suffixes (e.g. openai/gpt-4:free) and resolves known slug aliases.

### Example Usage

```python
from openrouter import OpenRouter
import os


with OpenRouter(
    http_referer="<value>",
    x_open_router_title="<value>",
    x_open_router_categories="<value>",
    api_key=os.getenv("OPENROUTER_API_KEY", ""),
) as open_router:

    res = open_router.models.get(author="openai", slug="gpt-4")

    # Handle response
    print(res)

```

## list_for_user

List models filtered by user provider preferences, [privacy settings](https://openrouter.ai/docs/guides/privacy/provider-logging), and [guardrails](https://openrouter.ai/docs/guides/features/guardrails). If requesting through `eu.openrouter.ai/api/v1/...` the results will be filtered to models that satisfy [EU in-region routing](https://openrouter.ai/docs/guides/privacy/provider-logging#enterprise-eu-in-region-routing).

### Example Usage

```python
from openrouter import OpenRouter, operations
import os


with OpenRouter(
    http_referer="<value>",
    x_open_router_title="<value>",
    x_open_router_categories="<value>",
) as open_router:

    res = open_router.models.list_for_user(security=operations.ListModelsUserSecurity(
        bearer=os.getenv("OPENROUTER_BEARER", ""),
    ))

    # Handle response
    print(res)

```
