Unverified片上SRAM提供了远超HBM的访问速度和带宽，消除了芯片到外部内存之间的数据搬运瓶颈74% similarUnverifiedFlash Attention reduces the number of reads and writes to GPU high-bandwidth memory by reorganizing the computation order, achieving a 2–4× speed improvement without changing the computation results.74% similarVerifiedCompared to the previous-generation V4 Flash, V4.1 Flash reduces the demand for high-bandwidth memory (HBM) to one-quarter and the demand for SSD persistent storage to one-eighth.72% similarUnverifiedDeepSeek V4.1 Flash reduces per-token storage from 3,500 bytes in the previous generation to approximately 890 bytes through KV cache inter-layer alternation and reuse optimization.70% similarUnverifiedFlash-type models typically reduce inference latency by 50-80%, lower API call costs by 60-90%, and maintain context windows in the range of 32K-128K tokens.70% similar
