Summary

User compares Qwen3.8 Flash-Next on Strata against a Qwen3.8 27B build for the RTX 5080 on NInfer, reporting 89-112 t/s decode on the 27B. Setup is NInfer on an RTX 5080 with 32GB DDR5, vision flags removed and thinking budget raised to 4096; the user plugged the display into the iGPU and reports 94.6% VRAM usage while using the desktop. The user says the 27B solved in one prompt a coding task that the Flash-Next coder and an IQ2_XS build needed multiple prompts for, and calls it insanely fast at prefill and decode.
