The update to num_speculative_tokens=2 for Hopper is consistent with recent kernel improvements mentioned in the PR description. However, DeepSeek-V4-Flash.yaml (lines 58-66) still contains the same num_speculative_tokens=1 override for Hopper. Since this improvement is hardware-dependent and applies to the MTP kernels used by both models, you should consider updating the Flash recipe as well to maintain consistency across the V4 model family and ensure optimal performance for all users on Hopper hardware.
