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.82% similarUnverifiedDeepSeek implements fully transparent automatic caching via prefix hash matching; as long as the prefixes of adjacent requests are completely identical at the byte level, caching takes effect automatically.75% similarUnverifiedIn 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.74% similarUnverifiedDeepSeek's API uses a context disk caching mechanism that persists KV Cache to high-speed NVMe SSD storage rather than retaining it only in GPU VRAM.72% similarUnverifiedWhen uploading files on the web version of DeepSeek, data is submitted to DeepSeek's server.69% similar
