Usually Sonnet 5 vs Opus 5. Coding delta versus output $/1M. The workhorse question.
Top Anthropic vs top Google. Usually Opus 5 vs 3.6 Pro. Two different invoices.
Not a frozen 2025 article. Today that is usually Opus 5 vs GPT-5.6 Sol. Dated cells, not a brand fight.
Jul 24 2026 official API at $5/$25 and a 1M window. Preference Elo is taste, not a coding exam.
