First local-LLM tuning attempt: Qwen3.8-27B true Q4_K_M at 13.2 tok/s near 50-61K context on RTX 5080 16GB

Explain Like I'm Normal

A community member successfully optimized the new Qwen 2.5/3 27B model to run at over 13 tokens per second with a massive 61k context window on a consumer RTX 5080. By utilizing Unsloth for tuning and specific GGUF quantization methods, they achieved high-fidelity coding performance that typically requires enterprise hardware. This demonstrates that mid-tier Blackwell cards can handle high-context RAG and coding tasks natively.
