Agent Usage
A public ledger of how I split work across Claude, Codex, and the rest of my agent stack. This page is rendered directly from the same serverless API that powers my personal usage tracking(TUT). Estimated cost is derived from current models.dev base rates.
Updated through Apr 16, 2026
Whole-stack footprint
2Btotal tokens
22,017 agent events from Oct 9, 2025 to Apr 16, 2026. Cache reads contribute 87.1%, which says more about how much context gets reused than a plain request count ever could. Current published base rates put the archive at about $1.4K.
