Gemini 4 Argon leads Claude Opus 5.5 on DeepSWE but trails on Terminal-Bench
Gemini 4 Argon scores 77.9% vs Opus 5.5's 74.2% on DeepSWE real-code fixes, but trails 57.4% to 66.4% on Terminal-Bench, at half the output price.
Gemini beats Claude at coding. Claude beats Gemini at coding. Both are true. On DeepSWE, fixing real code, Gemini 4 Argon leads: 77.9% vs 74.2%. On Terminal-Bench, working in a terminal, Claude Opus 5.5 leads: 66.4% vs 57.4%. At operating a computer, GPT-6 Astra beats both. The part that never makes the headline: most of these scores come from the companies themselves. Every launch chart is made by someone selling the model. So “best AI” usually means “best at this test.” The bill is easier to read. Per million output tokens: GPT-6 Astra $50. Claude Opus 5.5 $20. Gemini 4 Argon $10, for now. Same “best” label. Up to 5x the bill.
