Drafter checkpoints for EvSpark: a small distilled drafter that accelerates single-stream Evo2 7B (StripedHyena2) generation while staying distributionally lossless. Numbers: Evo2 7B bf16, single stream, RTX 4090, 48 genomic prompts × 1024 tokens, 3 training seeds. One checkpoint serves any decode-time draft length γ′ ≤ training γ (exact causal prefix; no retraining). Beyond 7B: the same drafter recipe retrained for Evo2 20B / 40B reaches 2.18–2.46× (real-43) and 2.51–2.78× (all-48) on one H20 (SDPA), and a predictor-guided regulatory-DNA design workflow sees a median 1.57× complete-design speedup over a calibrated batched native baseline (see paper). All four files are single-layer L27…
