Baseline (Jun–Dec 2023): ~24–92 commits/month. Moderate activity, no consistent AI coding tooling yet.
Early 2024 dip (Jan–Mar 2024): Activity dropped to 18–41. Claude 3 arrived March 2024.
Sep 2024 inflection (+o1-preview): Jumped to 179 — first major reasoning model (o1-preview, Sep 12).
Dec 2024 surge: 158 — coincides with full o1 release (Dec 5) and o3 announcement.
Feb 2025: 113 with Claude 3.7 Sonnet (extended thinking).
Sep–Oct 2025 explosion: 519 → 597 — Claude Sonnet 4.5 + Haiku 4.5 era, GPT-5 in Aug. This is a ~7-8× jump from the Jun 2023 baseline average.
Feb–Apr 2026 sustained peak: 324, 455, 311 — Claude Opus/Sonnet 4.6 era.

The correlation between major reasoning/coding model releases and productivity spikes is striking.
