DeepSeek-V4 compute optimization, broken down in DSpark
The video walks through DSpark, a paper on DeepSeek-V4’s inference-side optimization strategy. The core claim is that the lab pushed speculative decoding much further than usual, combining theory with practical serving considerations.
The presenter frames it as a rare example of a lab sharing aggressive compute min-maxing in a way that is both technically interesting and operationally useful for deployment.
