Unexpected weekly usage increase

On Aug. 19–20, while running a Codex workload, my weekly usage increased roughly 35–40 percentage points in under four hours, reaching approximately 65%. I’ve run comparable workloads many times before and would normally have expected the run to consume closer to 10 percentage points. The increase was significant enough that I stopped the runs before they finished.

I was using Sign in with ChatGPT. I read Tibo’s post on X today (https://x.com/thsottiaux/status/2090675027670978569) mentioning sub2api as a possible early finding in some of the cases OpenAI reviewed. I had never heard of sub2api before that post and have never used it. The explanation Tibo described does not align with my experience.

I wanted to add this here as another data point for the team. Based on the usage data and telemetry available to me, this run was a clear outlier compared with my previous comparable runs.

Appreciate the team looking into it. I’m happy to provide timestamps or sanitized telemetry if useful.
