User shares optimized Qwen3.8 27B setup for local LLM deployment

By PulseAugur Editorial · [1 sources] ·

A Reddit user shared a detailed setup for running the Qwen3.8 27B model locally, optimizing performance on a Debian 13 system with a 7900XTX GPU. The user found success with an unsloth-quantized version of the model, specifically `Qwen3.8-27B-UD-IQ4_XS.gguf`, achieving speeds of 22-30 tokens/second. Key to the performance was adjusting the `llama-server` command with parameters like `--spec-draft-p-min` to manage multi-turn conversation efficiency and utilizing KV cache quantization. AI
