Latest change
Modal and Decagon published a joint walkthrough showing how speculative decoding cut their inference latency to state-of-the-art levels, moving the technique from benchmark claims into a reproducible production serving recipe.
Earlier contextThe story so far
In mid-June speculative decoding moved from a research trick toward a default inference-latency lever. It surfaced alongside the GLM-5.2 open-model release as IndexShare, then NVIDIA reported DFlash speculative decoding lifting throughput up to 15x on Blackwell — pulling the technique into both the open-model and hardware-vendor conversations within a week.

What to watch — open questions
- How portable are these speedups across model families and prompt mixes, versus the cherry-picked workloads in vendor posts?
- Are the 15x (Blackwell/DFlash) and 'state-of-the-art' (Modal/Decagon) figures vendor-reported or independently confirmed?
- Does speculative decoding's accuracy/quality trade-off hold up under agentic, multi-turn workloads?
