 **🚀 Easy Model Management**
 - **Multiple Models Simultaneously**: Run different models at the same time (7B for speed, 70B for quality)
+- **Dynamic Multi-Model Instances**: llama.cpp router mode - serve multiple models from a single instance with on-demand loading
 - **Smart Resource Management**: Automatic idle timeout, LRU eviction, and configurable instance limits
 - **Web Dashboard**: Modern React UI for managing instances, monitoring health, and viewing logs

 ### Authentication Configuration
 
+llamactl supports two types of authentication:
+
+- **Management API Keys**: For accessing the web UI and management API (creating/managing instances). These can be configured in the config file or via environment variables.
+- **Inference API Keys**: For accessing the OpenAI-compatible inference endpoints. These are managed via the web UI (Settings → API Keys) and stored in the database.
+
 ```yaml
 auth:
   require_inference_auth: true           # Require API key for OpenAI endpoints (default: true)
-  inference_keys: []                     # List of valid inference API keys
   require_management_auth: true          # Require API key for management endpoints (default: true)
   management_keys: []                    # List of valid management API keys
 ```
 
+**Managing Inference API Keys:**
+
+Inference API keys are managed through the web UI or management API and stored in the database. To create and manage inference keys:
+
+1. Open the web UI and log in with a management API key
+2. Navigate to **Settings → API Keys**
+3. Click **Create API Key**
+4. Configure the key:
+   - **Name**: A descriptive name for the key
+   - **Expiration**: Optional expiration date
+   - **Permissions**: Grant access to all instances or specific instances only
+5. Copy the generated key - it won't be shown again
+
 **Environment Variables:**
 - `LLAMACTL_REQUIRE_INFERENCE_AUTH` - Require auth for OpenAI endpoints (true/false)
-- `LLAMACTL_INFERENCE_KEYS` - Comma-separated inference API keys
 - `LLAMACTL_REQUIRE_MANAGEMENT_AUTH` - Require auth for management endpoints (true/false)
 - `LLAMACTL_MANAGEMENT_KEYS` - Comma-separated management API keys

+## Multi-Model llama.cpp Instances
+
+!!! info "llama.cpp Router Mode"
+    llama.cpp instances support [**router mode**](https://huggingface.co/blog/ggml-org/model-management-in-llamacpp), allowing a single instance to serve multiple models dynamically. Models are loaded on-demand from the llama.cpp cache without restarting the instance.
+
+### Creating a Multi-Model Instance
+
+**Via Web UI**
+
+1. Click **"Create Instance"**
+2. Select **Backend Type**: "Llama Server"
+3. Leave **Backend Options** empty `{}` or omit the model field
+4. Create the instance
+
+**Via API**
+
+```bash
+# Create instance without specifying a model (router mode)
+curl -X POST http://localhost:8080/api/v1/instances/my-router \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <token>" \
+  -d '{
+    "backend_type": "llama_cpp",
+    "backend_options": {},
+    "nodes": ["main"]
+  }'
+```
+
+### Managing Models
+
+**Via Web UI**
+
+1. Start the router mode instance
+2. Instance card displays a badge showing loaded/total models (e.g., "2/5 models")
+3. Click the **"Models"** button on the instance card
+4. Models dialog opens showing:
+    - All available models from llama.cpp instance
+    - Status indicator (loaded, loading, or unloaded)
+    - Load/Unload buttons for each model
+5. Click **"Load"** to load a model into memory
+6. Click **"Unload"** to free up memory
+
+**Via API**
+
+```bash
+# List available models
+curl http://localhost:8080/api/v1/llama-cpp/my-router/models \
+  -H "Authorization: Bearer <token>"
+
+# Load a model
+curl -X POST http://localhost:8080/api/v1/llama-cpp/my-router/models/Mistral-7B-Instruct-v0.3.Q4_K_M.gguf/load \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <token>" \
+  -d '{"model": "Mistral-7B-Instruct-v0.3.Q4_K_M.gguf"}'
+
+# Unload a model
+curl -X POST http://localhost:8080/api/v1/llama-cpp/my-router/models/Mistral-7B-Instruct-v0.3.Q4_K_M.gguf/unload \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <token>" \
+  -d '{"model": "Mistral-7B-Instruct-v0.3.Q4_K_M.gguf"}'
+```
+
+### Using Multi-Model Instances
+
+When making inference requests to a multi-model instance, specify the model using the format `instance_name/model_name`:
+
+```bash
+# OpenAI-compatible chat completion with specific model
+curl -X POST http://localhost:8080/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <inference-key>" \
+  -d '{
+    "model": "my-router/Mistral-7B-Instruct-v0.3.Q4_K_M.gguf",
+    "messages": [
+      {"role": "user", "content": "Hello!"}
+    ]
+  }'
+
+# List all available models (includes multi-model instances)
+curl http://localhost:8080/v1/models \
+  -H "Authorization: Bearer <inference-key>"
+```
+
+The response from `/v1/models` will include each model from multi-model instances as separate entries in the format `instance_name/model_name`.
+
+### Model Discovery
+
+Models are automatically discovered from the llama.cpp cache directory. The default cache locations are:
+
+- **Linux/macOS**: `~/.cache/llama.cpp/`
+- **Windows**: `%LOCALAPPDATA%\llama.cpp\`
+
+Place your GGUF model files in the cache directory, and they will appear in the models list when you start a router mode instance.
+

 Llamactl proxies all requests to the underlying backend instances (llama-server, MLX, or vLLM).
