Claude Code share of T3 Code turns jumps from 52% to 78% after Opus 5.5 launch
FinanceYF5 · x · 2026-11-10
Real-world usage stats from T3 Code show Claude Code's share of user-started turns climbing from 52% (7 days before Opus 5.5) to 64% (7 days after), 75% over the last week, and roughly 78% on the latest single day. The author notes the two harnesses had long hovered around an even split — a shift this one-sided has never been seen before. Rare model-competition data based on actual user behavior rather than benchmarks.
