# Models

> Model information endpoints

## 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
* [listForUser](#listforuser) - 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

```typescript theme={null}
import { OpenRouter } from "@openrouter/sdk";

const openRouter = new OpenRouter({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const result = await openRouter.models.get({
    author: "openai",
    slug: "gpt-4",
  });

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript theme={null}
import { OpenRouterCore } from "@openrouter/sdk/core.js";
import { modelsGet } from "@openrouter/sdk/funcs/modelsGet.js";

// Use `OpenRouterCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const openRouter = new OpenRouterCore({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const res = await modelsGet(openRouter, {
    author: "openai",
    slug: "gpt-4",
  });
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("modelsGet failed:", res.error);
  }
}

run();
```
