Qwen3-Coder Benchmark: Code Skills vs Claude Sonnet

Can local code models compete with cloud? We ran 10 task comparisons between Qwen3-Coder-Next (Q4) and Claude Sonnet 4.6. Final: Claude 87 vs Qwen 80.

Results

• REST API dev: Tie (9/10 each)
• DevOps configs: Qwen wins (9 vs 7) — trained on server data
• SQL optimization: Qwen wins (8 vs 7)
• Frontend/CSS: Claude wins (9 vs 8) — code models lack visual intuition
• Algorithm/regex: Claude wins by 2 points — general models reason better

Conclusion

Qwen3-Coder handles 80% of daily coding at zero local cost. The remaining 20% complex scenarios (architecture, algorithms) go to Claude. This is why our ACP uses Qwen-Coder as primary with Claude as the safety net.
