I Ran 10 AI Coding Models Through 5 Tasks: A Data Scientist's Take

Short summary

A data scientist benchmarked 10 AI coding models across 5 tasks (function implementation, bug fix, algorithm, code review, full feature) and found no statistically significant correlation between price and quality (r=0.31, p≈0.38). Cheap models like DeepSeek V4 Flash and Qwen3-Coder-30B scored within 0.3 points of premium models costing 10x more. The open-source Chinese ecosystem dominated, with three of the top five being DeepSeek or Qwen variants.

  • •10 coding LLMs benchmarked across 5 tasks with a 1-10 rubric; no significant price-quality correlation found
  • •DeepSeek and Qwen variants dominated the top ranks at fraction of premium-model cost
  • •DeepSeek-R1 scored highest (9.4) but cost 10x more than near-equivalent cheaper models
