short_description: Run GGUF models (Qwen2.5, Gemma-3, Phi-4) with llama.cpp
---

This Streamlit app lets you run **chat-based inference** on different GGUF models with `llama.cpp` and `llama-cpp-python`. 

### 🔄 Supported Models:
- `Qwen/Qwen2.5-7B-Instruct-GGUF` → `qwen2.5-7b-instruct-q2_k.gguf`
- `unsloth/gemma-3-4b-it-GGUF` → `gemma-3-4b-it-Q5_K_M.gguf`
- `unsloth/Phi-4-mini-instruct-GGUF` → `Phi-4-mini-instruct-Q5_K_M.gguf`

### ⚙️ Features:
- Model selection in sidebar
- Custom system prompt and generation parameters
- Chat-style UI with streaming responses

### 🧠 Memory-Safe Design (for HuggingFace Spaces):
- Only **one model is loaded at a time** (no persistent memory bloat)
- Uses **manual unloading and `gc.collect()`** to free memory when switching
- Reduces `n_ctx` context length to stay under 16 GB RAM limit
- Automatically downloads models only when needed
- Trims history to the **last 8 user-assistant turns** to avoid context overflow

Perfect for deploying multi-GGUF chat models on **free-tier HuggingFace Spaces**!
