V4.1 Flash KV cache is 437x smaller than V1, easing China's memory bottleneck
ChrisGPT · x · 2026-09-10
Follow-up on DeepSeek V4.1 Flash: KV cache compressed to just 890 bytes/token — 437x smaller than DeepSeek V1. Since one of China's biggest bottlenecks is memory, this means dramatically more concurrent context fits in the same HBM, boosting inference throughput and concurrency.
