1. LM Studio — point-and-click

Open LM Studio, search “Qwen2.5 0.5B Instruct”, and download a quant that fits your VRAM (≈2 GB at Q4_K_M). Load it and chat — fully offline. It also serves a local OpenAI-compatible API you can point Spanvero at.

2. llama.cpp — maximum control

Grab a community GGUF build of Qwen2.5 0.5B Instruct from Hugging Face (search “Qwen2.5 0.5B Instruct GGUF” — bartowski and unsloth publish reliable ones), then run:

./llama-cli -m <Q4_K_M-file>.gguf -p "Hello" -ngl 99

Or serve it with ./llama-server -m <file>.gguf for an OpenAI-compatible API on :8080.
