Wire an app to 500+ LLMs through one OpenRouter interface with cost-aware routing and SDK adapters (Vercel AI SDK, LangChain, OpenAI SDK).

About

OpenRouter SDK plugin giving an app a single unified interface to 500+ LLM models with intelligent routing and cost optimization. Developers use it during integration to swap or fan out across model providers without rewriting client code, with framework adapters for Vercel AI SDK, LangChain, OpenAI SDK, and PydanticAI.

Unified access to 500+ LLM models
Intelligent routing + cost optimization

OpenRouter Plugin

Unified interface for 500+ LLM models with intelligent routing, cost optimization, and framework integrations.

Overview

The OpenRouter plugin provides comprehensive SDK integration for accessing 500+ models from 60+ providers including OpenAI, Anthropic, Google, Meta, and more. It supports intelligent model routing, cost optimization, and seamless integration with popular frameworks like Vercel AI SDK and LangChain.

Features

500+ Models: Access to models from OpenAI, Anthropic, Google, Meta, Mistral, and more
Intelligent Routing: Cost-aware model selection and automatic fallback strategies
Framework Integration: Vercel AI SDK, LangChain, OpenAI SDK, PydanticAI support
Cost Optimization: Budget controls, usage tracking, and cost-effective routing
Multi-Language: TypeScript, JavaScript, and Python support

Commands

`/openrouter:init [project-path]`

Initialize OpenRouter SDK with API key configuration, model selection, and framework integration setup.

Example:

/openrouter:init

`/openrouter:add-vercel-ai-sdk [feature]`

Add Vercel AI SDK integration with OpenRouter provider for streaming, chat, and tool calling.

Features: streaming, chat, tools, all

Example:

/openrouter:add-vercel-ai-sdk streaming
/openrouter:add-vercel-ai-sdk all

`/openrouter:add-langchain [feature]`

Add LangChain integration with OpenRouter for chains, agents, and RAG.

Features: chains, agents, rag, all

Example:

/openrouter:add-langchain agents
/openrouter:add-langchain all

`/openrouter:add-model-routing [routing-strategy]`

Configure intelligent model routing and cost optimization with fallback strategies.

Strategies: cost, speed, quality, balanced, custom

Example:

/openrouter:add-model-routing cost
/openrouter:add-model-routing balanced

`/openrouter:configure [setting-name] [value]`

Configure OpenRouter settings, API keys, and preferences.

Actions: set, get, list, reset

Example:

/openrouter:configure set api-key sk-or-v1-...
/openrouter:configure get
/openrouter:configure list

Agents

openrouter-setup-agent: Initialize OpenRouter SDK with framework detection and environment setup
openrouter-vercel-integration-agent: Integrate Vercel AI SDK with OpenRouter provider
openrouter-langchain-agent: Integrate LangChain with OpenRouter for chains, agents, and RAG
openrouter-routing-agent: Configure intelligent model routing and cost optimization

Quick Start

Initialize OpenRouter:
```
/openrouter:init
```
Get your API key at https://openrouter.ai/keys
Choose your integration:
- For Next.js apps: /openrouter:add-vercel-ai-sdk all

LangChain (Python/TypeScript)

Chain composition with LCEL
Agent development with tools
RAG with vector stores (Chroma, FAISS, Pinecone)
Memory and conversation history

OpenAI SDK (TypeScript/Python)

Drop-in replacement for OpenAI API
Compatible with existing OpenAI code
Access to 500+ models via routing

Model Routing

OpenRouter provides intelligent routing to optimize for cost, speed, or quality:

Cost-optimized: Free models → low-cost → premium fallback
Speed-optimized: Fastest models with streaming enabled
Quality-optimized: Premium models with high-quality fallbacks
Balanced: Task-based dynamic routing with cost/quality tradeoffs

Popular Models

anthropic/claude-3.5-sonnet: Best quality, great for complex tasks
openai/gpt-4-turbo: High quality, strong reasoning
google/gemini-pro-1.5: Cost-effective, good performance
meta-llama/llama-3.1-70b-instruct: Open source, free tier available
