AI usage

Every token I spend on AI coding, by day, for the last year: Codex, Claude Code, Cursor and OpenCode. AgentsView and CodexBar do the counting, and genai-prices supplies the rates.

None of this is money that left my account — I pay by subscription. It is what the same tokens would have cost at API list prices.

Is Sai token maxxxing yet?

Warming up.
