Qwen3-8B-speculator.eagle3

Model Overview

• Verifier: Qwen/Qwen3-8B
• Speculative Decoding Algorithm: EAGLE-3
• Model Architecture: Eagle3Speculator
• Release Date: 07/27/2025
• Version: 1.0
• Model Developers: RedHat

This is a speculator model designed for use with Qwen/Qwen3-8B, based on the EAGLE-3 speculative decoding algorithm. It was trained using the speculators library on a combination of the Aeala/ShareGPT_Vicuna_unfiltered and the HuggingFaceH4/ultrachat_200k datasets. The model was trained with thinking turned disabled. This model should be used with the Qwen/Qwen3-8B chat template, specifically through the /chat/completions endpoint.

Use with vLLM

vllm serve Qwen/Qwen3-8B \
  -tp 1 \
  --speculative-config '{
    "model": "RedHatAI/Qwen3-8B-speculator.eagle3",
    "num_speculative_tokens": 3,
    "method": "eagle3"
  }'
