poolside/Laguna-S-2.1-DFlash-NVFP4
DFlash speculator for the NVFP4 target poolside/Laguna-S-2.1-NVFP4. The speculator is a 6-layer Laguna-style draft model (BF16); pair it with the NVFP4 base for lower-latency serving via speculative decoding.
Trained: e0630_rhiemann_baseline SFT, DFlash Stage-2, 15k steps. Recommended serving setting: num_speculative_tokens=7. DFlash upstream support is in progress (vLLM #46853, SGLang #29446, TRT-LLM #15666). Use poolside/Laguna-S-2.1-NVFP4 as the target model.
Benchmarks
Measured with TP=2, temperature=0, and num_speculative_tokens=15.
