Why this result

GPT-5.6 Sol is clearly ahead on the BenchAlign aggregate, 81.96 to 56.97. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5.6 Sol's sharpest advantage is in agentic, where it averages 92 against 51. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 91.9% to 40.5%.

GPT-5.6 Sol is also the more expensive model on tokens at $5.00 input / $30.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.5-35B-A3B. That is roughly Infinityx on output cost alone. GPT-5.6 Sol gives you the larger context window at 1M, compared with 262K for Qwen3.5-35B-A3B.
