Quick briefing — cleaned from the original RSS feed
SparseSpec-L: How a Sparse KV Cache Makes Long-Context LLM Inference 2.79× Faster — Without Any Training Speculative decoding has become one of the more practical tools for cutting LLM inference latency. The idea is simple: use a fast draft mechanism to propose several tokens at once, then let the full model verify them in a single parallel pass. When the draft is good, you get multiple tokens for roughly the cost of one. The catch is that most setups require a separate draft model — a smaller…
