Summary

User reports Qwen3.8-27B at ~39 tok/s fully GPU-offloaded on an RTX 4080 SUPER 16GB, with ~200-230 ms TTFT on short tasks. Setup is LM Studio on Windows 11 with the Ubuntu Codex CLI, on a 5800X3D with 3000mhz DDR4. On a real 26K-token workload the speed is ~34 tok/s. The user finds it surprisingly capable for local coding and agent work but too inconsistent to replace a hosted model, and an excellent local workhorse for bounded tasks.
