Summary

A new KV cache optimization called kvflash doubles generation speed and reduces VRAM usage for Qwen 3.6-27B on a single RTX 3090 while maintaining accuracy.

"Qwen3.6-27B Q4\_K\_M on a single RTX 3090: native 256K context at 38.6 tok/s with 72 MiB of resident KV, needle recall 88-100% at 6% residency, harness accuracy unchanged (36/36 vs full cache)." On the same hardware, generation speeds doubled and VRAM usage dropped significantly (21GB to 17.5GB) while maintaining full context accuracy Yt video of fahd --> [https://youtu.be/8rTVCRWvRDo?si=MYiVrQQltbSsMAOP](https://youtu.be/8rTVCRWvRDo?si=MYiVrQQltbSsMAOP) Link to git hub - [https://github.com/Luce-Org/lucebox-hub/tree/main/optimizations/kvflash](https://github.com/Luce-Org/lucebox-hub/tree/main/optimizations/kvflash) Quality loss?? --> Quality verdict (harness ground truth, base-vs-base control included): full results in RESULTS.md. Outputs are not guaranteed byte-identical to the full cache on long generations (the masked kernel path rounds differently — a different deterministic lineage), but correctness is identical: 36/36 vs 36/36 across HumanEval, GSM, MATH, and agent suites.
