How to use from
SGLang
Install from pip and serve model
# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
    --model-path "RedHatAI/Qwen3-30B-A3B-Instruct-2507-speculator.eagle3" \
    --host 0.0.0.0 \
    --port 30000
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:30000/v1/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "RedHatAI/Qwen3-30B-A3B-Instruct-2507-speculator.eagle3",
		"prompt": "Once upon a time,",
		"max_tokens": 512,
		"temperature": 0.5
	}'
Use Docker images
docker run --gpus all \

Model Overview

  • Verifier: Qwen3-30B-A3B-Instruct-2507
  • Speculative Decoding Algorithm: EAGLE-3
  • Model Architecture: Eagle3Speculator
  • Release Date: 12/12/2025
  • Version: 1.0
  • Model Developers: RedHat

This is a speculator model designed for use with Qwen3-30B-A3B-Instruct-2507 , based on the EAGLE-3 speculative decoding algorithm. It was trained using the speculators library on a combination of the Magpie-Align/Magpie-Pro-300K-Filtered and the HuggingFaceH4/ultrachat_200k datasets. The model was trained with thinking turned disabled. This model should be used with the Qwen3-30B-A3B-Instruct-2507 chat template, specifically through the /chat/completions endpoint.

Use with vLLM

vllm serve Qwen3-30B-A3B-Instruct-2507 \
  -tp 1 \
  --speculative-config '{
    "model": "RedHatAI/Qwen3-30B-A3B-Instruct-2507-speculator.eagle3",
    "num_speculative_tokens": 3,
    "method": "eagle3"
  }'
