What issue are you seeing?

Hi,

After I started using the Codex App, Codex credit usage appears to have jumped abnormally.

From the usage chart, I spent more credits in the last 4 days (from 11th to 14th - Codex App) than in the previous 7 days (4th to 10th - VSCode's Codex Extension), which does not match my expected usage pattern. This makes me suspect a bug in credit accounting, double-counting, or incorrect attribution to the Codex App.

Actual

Codex App usage seems to correspond with a disproportionate increase in charged credits.

thanks a lot.

What steps can reproduce the bug?

Suspected sequence

1. Use VSCode's Codex Extension
2. Use Codex App
3. Credit usage jumps sharply in the last 4 days

What is the expected behavior?

Credits should track actual usage consistently across clients.
