+# llama.cpp Server Script Plan for ProxmoxVE
+
+## Overview
+
+This plan outlines the creation of a ProxmoxVE LXC container script for deploying **llama.cpp server** with GPU passthrough and Vulkan backend support. The script will install the latest Vulkan build and configure a default model for immediate use.
+
+## Reference Links
+
+- **GitHub Discussion**: https://github.com/community-scripts/ProxmoxVE/discussions/2403
+- **llama.cpp Repository**: https://github.com/ggml-org/llama.cpp
+- **llama.cpp Server Documentation**: https://github.com/ggml-org/llama.cpp/tree/master/tools/server
+- **Vulkan Build Downloads**: https://github.com/ggml-org/llama.cpp/releases
+
+## Implementation Status
+
+✅ **COMPLETED** - All files have been created.
+
+## Files Created
+
+### 1. Container Script: `ct/llamacpp.sh`
+
+**Purpose**: Main script for creating the LXC container
+
+**Key Features**:
+- Debian 13 base (recommended for latest Vulkan support)
+- GPU passthrough enabled via `var_gpu="yes"`
+- 4 CPU cores, 8GB RAM minimum (model requires ~10GB for Q8_0)
+- 20GB disk (model + binaries + cache)
+- Auto-detects GPU type (AMD/Intel/NVIDIA) during updates
+- Downloads appropriate build (Vulkan or CUDA)
+
+### 2. Installation Script: `install/llamacpp-install.sh`
+
+**Purpose**: Install llama.cpp with Vulkan support inside the container
+
+**Key Features**:
+- Auto-detects GPU vendor (AMD/Intel/NVIDIA)
+- Downloads latest Vulkan build from GitHub releases
+- Falls back to Vulkan if CUDA download fails
+- Creates systemd service with default model
+- Configures GPU permissions automatically
+- Creates GPU passthrough documentation file
+
+### 3. JSON Metadata: `frontend/public/json/llamacpp.json`
+
+**Purpose**: Frontend metadata for the script catalog
+
+**Key Features**:
+- Category: AI/ML (0)
+- Port: 8080
+- Updateable: true
+- Comprehensive notes for GPU passthrough
+
+### 4. Header File: `ct/headers/llamacpp`
+
+**Purpose**: ASCII art header for the script
+
+## Default Configuration
+
+| Setting | Value |
+|---------|-------|
+| Model | `unsloth/Qwen3.5-9B-GGUF:Q8_0` |
+| Port | 8080 |
+| Context Size | 8192 tokens |
+| GPU Layers | -1 (all layers on GPU) |
+| Host | 0.0.0.0 (all interfaces) |
+
+## GPU Passthrough Configuration
+
+### AMD GPU Configuration
+
+Add to `/etc/pve/lxc/<CTID>.conf`:
+```ini
+dev0: /dev/kfd,gid=104
+dev1: /dev/dri/renderD128,gid=104
+lxc.cgroup2.devices.allow: c 226:0 rwm
+lxc.cgroup2.devices.allow: c 226:128 rwm
+```
+
+### Intel GPU Configuration
+
+Add to `/etc/pve/lxc/<CTID>.conf`:
+```ini
+dev0: /dev/dri/renderD128,gid=104
+lxc.cgroup2.devices.allow: c 226:128 rwm
+```
+
+### NVIDIA GPU Configuration
+
+For NVIDIA, use the nvidia-container-toolkit approach:
+```ini
+lxc.cgroup2.devices.allow: c 195:* rwm
+lxc.cgroup2.devices.allow: c 509:* rwm
+```
+
+## API Endpoints
+
+The server provides OpenAI-compatible endpoints:
+
+| Endpoint | Description |
+|----------|-------------|
+| `POST /v1/chat/completions` | Chat completion |
+| `POST /v1/completions` | Text completion |
+| `POST /v1/embeddings` | Text embeddings |
+| `GET /v1/models` | List available models |
+| `GET /health` | Health check |
+| `GET /` | Built-in Web UI |
+
+## Resource Requirements
+
+| Resource | Minimum | Recommended |
+|----------|---------|-------------|
+| CPU | 2 cores | 4+ cores |
+| RAM | 8GB | 16GB+ |
+| Disk | 20GB | 50GB+ |
+| GPU | Vulkan 1.1+ | Vulkan 1.3+ |
+
+## Testing Checklist
+
+- [ ] Container creation succeeds
+- [ ] GPU passthrough is detected (`vulkaninfo` works)
+- [ ] llama.cpp server starts successfully
+- [ ] Model downloads automatically from HuggingFace
+- [ ] API responds on port 8080
+- [ ] Chat completion endpoint works
+- [ ] Update script functions correctly
+- [ ] Service restarts after reboot
+
+## Usage Examples
+
+### Chat Completion (curl)
+
+```bash
+curl http://localhost:8080/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "messages": [{"role": "user", "content": "Hello!"}],
+    "temperature": 0.7,
+    "max_tokens": 100
+  }'
+```
+
+### Change Model
+
+```bash
+# Edit the service file
+nano /etc/systemd/system/llamacpp.service
+
+# Change the -hf parameter
+# Example: -hf TheBloke/Llama-2-7B-GGUF:Q4_K_M
+
+# Reload and restart
+systemctl daemon-reload
+systemctl restart llamacpp
+```
+
+### Check Logs
+
+```bash
+journalctl -u llamacpp -f
+```
+
+## Files Summary
+
+| File | Purpose |
+|------|---------|
+| `ct/llamacpp.sh` | Container creation script |
+| `install/llamacpp-install.sh` | Installation script |
+| `frontend/public/json/llamacpp.json` | Frontend metadata |
+| `ct/headers/llamacpp` | ASCII art header |
+| `plans/llamacpp-server-plan.md` | This documentation |
+
+## Next Steps
+
+1. Test the script on a Proxmox VE 8.x host with GPU passthrough
+2. Verify GPU detection works for AMD, Intel, and NVIDIA
+3. Test model download and inference
+4. Verify update mechanism works correctly
