# Overview

> Unified model routing and multimodal task entry point, compatible with mainstream protocols and channels

## Quick Introduction

Model Router provides a unified model routing and multimodal task entry point, compatible with mainstream protocols and channels.

* One entry point covers mainstream models and tasks, compatible with OpenAI-style calls without changing SDKs
* Preserves native paths for Claude, Gemini, and others to reduce migration and switching costs
* Built-in stability, quota settlement, notifications, and security policies to help you confidently integrate in production

**Base URL**: `https://app.memorylake.ai` — OpenAI-compatible at `/v1`, Claude-native at `/claude/v1`, Gemini-native at `/gemini/:version`. Authenticate with the same `sk-…` key you use elsewhere on the platform ([details](/authentication)).

<Note>
  Looking to add **memory** to your LLM calls rather than just route them? See [Memory Router](/features/memory-router/overview), which layers persistent memory on top of the same protocols.
