Supports variant suffixes (e.g. openai/gpt-4:free) and resolves known slug aliases. ### Example Usage ```python theme={null} from openrouter import OpenRouter import os with OpenRouter( http_referer="", x_open_router_title="", x_open_router_categories="", api_key=os.getenv("OPENROUTER_API_KEY", ""), ) as open_router: res = open_router.models.get(author="openai", slug="gpt-4") # Handle response print(res) ``` ### Parameters | Parameter | Type | Required | Description | Example | | -------------------------- | ------------------------------------------------------------------- | -------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | | `author` | *str* | :heavy\_check\_mark: | The author/organization of the model | openai | | `slug` | *str* | :heavy\_check\_mark: | The model slug, optionally including a variant suffix (e.g. gpt-4 or gpt-4:free) | gpt-4 | | `http_referer` | *Optional\[str]* | :heavy\_minus\_sign: | The app identifier should be your app's URL and is used as the primary identifier for rankings.
