    DeepSeek-V4.1 Flash Targets Extreme KV Cache Compression

    A technical report on DeepSeek-V4.1 Flash describes a model redesign focused on reducing KV cache storage and prefill compute for long-context agent workloads. The paper combines architectural changes such as selective layer activation, multi-stage KV cache compression, sparse attention optimizations, and FP4 KV cache to improve throughput and lower deployment costs.
