Alibaba Cloud (Qwen)Qwen3.6-PlusVSOpenAIGPT-5.5

Analysis by:the whichllmmodel Editorial Team|Updated: June 2026

Our Take

We recommend GPT-5.5 if you need peak intelligence for reasoning and coding tasks, or the 10.0x cheaper Qwen3.6-Plus to optimize your budget for high-volume pipelines. While GPT-5.5 holds a clear performance lead, it carries a heavy price premium. Choose GPT-5.5 for complex logic, or Qwen3.6-Plus for budget efficiency.
WHY?
Benchmark Calculations & Evidence:
  • Coding Benchmarks: Both models were evaluated on the SWE-bench Pro benchmark. GPT-5.5 scored 58.6%, while Qwen3.6-Plus scored 56.6%.
  • Reasoning Benchmarks: Both models were evaluated on the GPQA Diamond benchmark. GPT-5.5 scored 93.6%, while Qwen3.6-Plus scored 90.4%.
  • Cost Efficiency: Qwen3.6-Plus pricing ($0.5/M input, $3/M output) is 10.0x cheaper than GPT-5.5 ($5/M input, $30/M output).
