EAGLE3 For Qwen/Qwen3-Coder-480B-A35B-Instruct

About

SpecBundle is an open-source initiative, jointly driven by the community and industry, to democratize speculative decoding by providing high-performance speculative decoding draft weights for mainstream open-source models.

This checkpoint was trained by the EigenAI Team and released as the phase 1 of SpecBundle release. We regenerated the responses in the OpenCoder-LLM/opc-sft-stage1 and trained the model on 1.4M data samples for 2 epochs. This checkpoint was trained using the SpecForge framework.

Usage

You can use this checkpoint with the command below.

export SGLANG_ALLOW_OVERWRITE_LONGER_CONTEXT_LEN=1

python3 -m sglang.launch_server \
    --model Qwen/Qwen3-Coder-480B-A35B-Instruct \
    --speculative-algorithm EAGLE3 \
    --speculative-draft-model-path lmsys/SGLang-EAGLE3-Qwen3-Coder-480B-A35B-Instruct-perfect-blend-regenerated \
    --speculative-num-steps 3 \
    --speculative-eagle-topk 1 \
    --speculative-num-draft-tokens 4 \
    --tp 8

Performance

This checkpoint exhibits superior performance on various benchmarks.

You can reproduce the performance with the command below:

# clone specforge
git clone https://github.com/sgl-project/SpecForge.git
cd SpecForge/benchmarks

# run benchmarks
python bench_eagle3.py \
        --model Qwen/Qwen3-Coder-480B-A35B-Instruct \
        --speculative-algorithm EAGLE3 \
        --speculative-draft-model-path lmsys/SGLang-EAGLE3-Qwen3-Coder-480B-A35B-Instruct-perfect-blend-regenerated \
