ForeSpark supercharges speculative decoding
SafeRoute-MAS introduces a message routing method for multi-agent systems that accounts for coverage and risk calibration in scientific reasoning.

š„ What happened
Researchers at the University of Washington unveiled ForeSpark, a system that jointly schedules draft and verification lengths per request. Under high load, up to 40% of step time goes to drafts that never get verified ā ForeSpark eliminates that waste.
š” Why it matters
On vLLM, ForeSpark boosts throughput by 1.77x over DSpark and 2.49x over autoregressive decoding at matched output quality. It also sustains 1.51x the request rate under latency SLOs.
ā” Our take
Finally, someone plugs the obvious leak: why draft full blocks when half get discarded? This isn't an academic niche ā it hits every serving pipeline.
