UnverifiedDeepSeek'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.77% similarUnverifiedDeepSeek has implemented cross-request KV Cache sharing on the server side, allowing cache hits as long as multiple requests share a consistent prefix74% similarVerifiedThe DeepSeek API offers significant discounts on cache-hit tokens.70% similarUnverifiedFor complex tasks, DeepSeek's token costs may actually be higher, because more manual intervention, more conversation rounds, and more corrective modifications are required, and it cannot query the internet.70% similarUnverifiedDeepSeek broke through the long-context bottleneck using techniques like sparse attention and positional encoding optimization.69% similar
