Codex usage limits seem to be draining unusually fast since 10 May 2026, even with light GPT-5.3 Codex use, while the usage-tracking UI also appears buggy or missing

I wanted to share a Codex usage issue I’ve been experiencing since 10 May 2026 , in case other developers are seeing the same thing.

My Codex limits appear to be getting consumed unusually fast. In my case, after only around 1 hour of light Codex usage , mostly using GPT-5.3 Codex / mini-level models , I was already close to hitting usage limits.

This feels abnormal because earlier I could use heavier models like GPT-5.4 with extra thinking for much longer, and the usage still stayed under control. Now, even lighter tasks seem to consume the limit extremely quickly.

The concerning part is that the usage-tracking UI also appears buggy. The section/function that should clearly show usage details is not showing properly or seems hidden, which makes it harder to understand what is actually consuming the limit.

I’m not saying this is definitely intentional. It could be a genuine bug, a recent change in how usage is calculated, or some issue with Codex sessions/workspaces consuming usage unexpectedly. But from a regular user’s perspective, it is not reassuring when:

• usage is consumed much faster than before,

• the usage tracking UI is not reliable,

• and users are being pushed toward buying extra credits without clear visibility into what caused the limit consumption.

I’ve also seen people online and heard from friends/colleagues that they are noticing similar behaviour recently. That makes me think this may not be an isolated issue.

Has anyone else experienced this since around 10 May 2026?

Specifically:

1. Codex weekly/daily limits getting consumed too quickly.

2. GPT-5.3 Codex or mini-level usage counting much heavier than expected.

3. Usage dashboard or tracking UI missing/buggy.

4. Limits being hit even without heavy or long-running tasks.

I’ve already contacted OpenAI Support and asked them to investigate the usage calculation.

Would appreciate hearing if other developers are seeing the same issue, especially regular Codex users who actively track their limits.
