Usually Sonnet 5 vs Opus 5. Coding delta versus output $/1M. The workhorse question.
Aug 10 2026 made the $2/$10 list permanent. Sonnet is the default Claude unless the repo is actually on fire.
Most of Opus 4.5 coding at a mid-tier price. Sonnet 5 replaced it as the buy; 4.5 remains a compare baseline.
