+## 🚀 Using OpenRouter (Recommended!)
+
+OpenRouter gives you access to 100+ AI models, many completely **FREE**. It's the easiest way to try different models without managing multiple API keys!
+
+### Why OpenRouter?
+- ✅ **100+ models** including Llama 3.3, Mistral, Claude, GPT-4, and more
+- ✅ **Many FREE models** with no credit card required
+- ✅ **Pay-as-you-go** - only pay for what you use
+- ✅ **Unified API** - same interface for all models
+- ✅ **Easy fallbacks** - automatically use alternative models if one fails
+
+### Quick Setup
+
+1. **Get OpenRouter API Key**
+   - Visit https://openrouter.ai
+   - Sign up (free, no credit card needed)
+   - Copy your API key from https://openrouter.ai/keys
+
+2. **Add to `.env.local`**
+   ```env
+   OPENROUTER_API_KEY=your_openrouter_api_key
+   ```
+
+3. **Select an OpenRouter Model**
+   - In the UI, find model names starting with `openrouter/`
+   - Try free models like:
+     - `meta-llama/llama-3.3-70b-instruct` (best free option)
+     - `mistralai/mistral-large`
+     - `cohere/command-r-plus`
+
+### Available OpenRouter Models
+
+**Free Models:**
+- Meta Llama 3.3 70B
+- Mistral Large
+- Cohere Command R+
+- And many more!
+
+**Premium Models:**
+- OpenAI GPT-4, GPT-4 Turbo
+- Anthropic Claude 3
+- Google Gemini
+
+Check https://openrouter.ai/models for the complete list and pricing.
+
+### API Endpoint
+
+Use the `/api/models` endpoint to browse available models:
+
+```bash
+# Get all OpenRouter models
+curl http://localhost:3000/api/models?provider=openrouter
+
+# Filter free models only
+curl http://localhost:3000/api/models?provider=openrouter&free=true
+
