AccRate (α=1.0) — EAGLE3 Draft Model for Qwen3-8B

Our method. Per-step loss weighted by token acceptance rate: w_s = 1 + α(1 − β_s), α=1.0.

Part of a course project evaluating per-step weighted loss functions for training EAGLE3 draft models. Full pipeline and source: https://github.com/XLOverflow/anlp_course_project

Collection: Qwen3 EAGLE3 — Weighted Loss Variants

Training

• Framework: SpecForge (our fork: https://github.com/XLOverflow/SpecForge)
• Target model: Qwen/Qwen3-8B
• Draft init: AngelSlim/Qwen3-8B_eagle3
• Data: ShareGPT-style reasoning traces (see scripts/data/ in project repo)
• Loss weight: w_s = 1 + α(1 − β_s), α=1.0
• Initialized from: baseline-uniform/epoch_4_step_82000
• Additional epochs: 1
• β_s profiled offline via scripts/train/profile_beta.py

Evaluation (Qwen3-8B target)

Dataset	τ (accept. length)	Speedup	Accuracy
GSM8K	7.359	4.588×	95.15%
MATH500	7.326	4.606×	95.20%

Baselines for reference: Vanilla ≈ 1× speedup, EAGLE-orig ≈ 2× speedup.

Usage

from huggingface_hub import snapshot_download
draft_path = snapshot_download(repo_id="XLOverflow/qwen3-eagle3-accrate")
# Then load with EAGLE's EaModel — see scripts/eval/eval_combined.py in the project repo.
