Qwen3-Coder-Next

Qwen3-Coder-Next is an open-weight language model designed specifically for coding agents and local development. This innovative model features a Mixture-of-Experts (MoE) architecture that achieves remarkable efficiency with only 3B activated parameters out of 80B total parameters, delivering performance comparable to models with 10–20x more active parameters.

The model excels at advanced agentic capabilities including long-horizon reasoning, complex tool usage, and recovery from execution failures, making it highly robust for dynamic coding tasks. With its 256K context length and adaptability to various scaffold templates, Qwen3-Coder-Next seamlessly integrates with different CLI/IDE platforms such as Claude Code, Qwen Code, Qoder, Kilo, Trae, and Cline, supporting diverse development environments. This makes it highly cost-effective for agent deployment while maintaining exceptional performance across various coding benchmarks.

***ations

• Memory Requirements: It is recommended to have >45GB unified memory or RAM/VRAM to run 4-bit quantized versions
• Optimal Quantization: For best results, use any 2-bit XL quant or above (requires >30GB unified memory/combined RAM + VRAM)
• Context Length: Default context length is 256K tokens. If you encounter out-of-memory issues or server startup failures, *** reducing the context length to a shorter value such as 32,768 tokens
• Sampling Parameters: For optimal performance, use temperature=1.0, top_p=0.95, top_k=40
• Model Updates: As of February 4, 2025, llama.cpp fixed a bug that caused Qwen to loop and have poor outputs. Ensure you're using the latest version of llama.cpp and updated GGUFs for improved outputs
• Inference Engines: The model is supported by various inference engines including SGLang (≥v0.5.8) and vLLM (≥0.15.0), as well as local tools like Ollama, LMStudio, MLX-LM, llama.cpp, and KTransformers
