vLLM Merges Hardware-Aware Dynamic Speculative Decoding
vllm_project · x · 2026-07-11
The vLLM project thanks the Cohere team for contributing and merging hardware-aware Dynamic SD into the main branch. This approach no longer uses a fixed number of draft tokens, but adapts dynamically based on batch size and hardware characteristics.
Key effects:
- Speedup where beneficial
- Auto-rollback where it might slow down inference
- Better suited for production environments with varying loads
The post also notes that speculative decoding can become slower at high batch sizes, making it hard for many production systems to directly adopt; this dynamic solution addresses that.
