UnverifiedIn DeepSeek's Context Caching mechanism, when the prefix content of multiple requests is identical, the server reuses previously computed KV Cache, significantly reducing computational costs and response latency.70% similarUnverifiedThe Hybrid Compressed Attention mechanism in DeepSeek V4 compresses KV Cache by aggregating Key-Value pairs from multiple tokens into more compact representations.70% similarUnverifiedDeepSeek uses automatic prefix matching, and the price of cached tokens can be as low as 1/50 of the original price.69% similarUnverifiedDeepSeek's API uses a context disk caching mechanism where the server computes a hash of the request prompt prefix and persists the KV Cache, requiring no explicit declaration of cache fields.68% similarUnverifiedDeepSeek's benchmark performance on mathematical reasoning and code generation is close to that of top-tier models, but its API call cost is significantly lower.66% similar
