Benchmark: DFlash1 vs DFlash2 Speed on Qwen Models
AlpinDale · x · 2026-08-20
A developer benchmarked the performance of DFlash1 and DFlash2 speculation decoding techniques on Qwen models:
- Speed: DFlash1 appears faster for Role Play (RP) tasks compared to DFlash2.
- Constraints: DFlash2 is currently limited to Qwen3.8 and caps speculative tokens at a maximum of 7, whereas DFlash1 supports higher limits (up to 15).
- Setup: Comparison ran on Qwen3.6-27B-FP8 (with DFlash1) vs Qwen3.8-27B-FP8 (with DFlash2).
