KVA Projection Method Boosts LLM Prefill Speed for Qwen3.8 Flash Next

r/LocalLLaMA, a first-party source, announced the development and adoption of KVA projections, based on Deepseek V4.1 Flash and HySparse2/MiMo-V3, for Qwen3.8 Flash Next. They claim this method delivers a 1.45-1.85x speedup in prefill to over 3k tokens, with a minor deficit to perplexity, tested on 2x R9700 with 128GB DDR5. r/MachineLearning reported that "Jev's calibration" was measured and "The LLMs won," likely referring to the performance gains from this new technique.
