  2. …GiB per session. Save/restore is exactly what DeepSeek does using its 3FS distributed filesystem: https://github.com/deepseek-ai/3fs#3-kvcache With this much cheaper setup backed by disks, they can offer much better caching experience: >…

  3. …If Anthropic got nothing here, then their inference cost can be much higher. DeepSeek also got https://github.com/deepseek-ai/3FS that makes cached reads a lot cheaper with way longer TTL. If Anthropic didn't need to invent and uses some…

  5. DeepSeek team, which is also an HFT shop, also implemented their DFS - https://github.com/deepseek-ai/3FS

  6. Deepseek has their own and they’re relatively small https://github.com/deepseek-ai/3FS It’s specialized knowledge, hard to do “correctly” (read posix here) but obtainable and implementable by a small team if you pick your battles right.…

  10. …is cool and all, but it's also stupid and their scale-out strategy is non-existent. This is why https://github.com/deepseek-ai/3FS came out but of course nobody had figured it out because they still think LLM's is like, chatbots, or…
