EAGLE3 For meta-llama/Llama-4-Scout-17B-16E-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 SpecForge Team and released as the phase 1 of SpecBundle release. We regenerated the responses in the mlabonne/open-perfectblend 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.

bash

export SGLANG_ALLOW_OVERWRITE_LONGER_CONTEXT_LEN=1

python3 -m sglang.launch_server \
    --model meta-llama/Llama-4-Scout-17B-16E-Instruct \
    --speculative-algorithm EAGLE3 \
    --speculative-draft-model-path lmsys/SGLang-EAGLE3-Llama-4-Scout-17B-16E-Instruct-SpecForge \
    --speculative-num-steps 3 \
    --speculative-eagle-topk 1 \
    --speculative-num-draft-tokens 4 \
    --tp 4

Performance

This checkpoint exhibits superior performance on various benchmarks.

Throughput	Acceptance Length

You can reproduce the performance with the command below:

bash

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