copilot-session-usage¶
copilot-session-usage reads VS Code Copilot debug logs and tells you how much each AI coding session cost in USD.
VS Code does not show session costs in its UI. The debug logs contain token counts per model. This tool reads those logs, applies the real published pricing (with cache discounts and long-context tiers), and prints a cost report in seconds.
The most common use: after a heavy agentic session, run
copilot-session-usage latest to see what it cost.
