What issue are you seeing?

Since around May 20, session limits are draining dramatically faster than before on GPT-5.5 Low for basic tasks (reading files, following instructions, nothing heavy).

• A single session now lasts ~60-70 minutes of actual work at best (on 5.5 low)
• Exhausted a full session with just 3 prompts on a separate Plus account
• Previously I could1h 20min continuous tasks without hitting even 40-50% usage — that's now impossible
• One task on GPT-5.5 Low ate 5% of the 5h window in 2m 37s (screenshot attached)

This is a clear regression. The burn rate has roughly doubled or worse compared to a week before.

Still happening after the May 22 incident was marked "resolved."

What steps can reproduce the bug?

1. Open Codex on any model (tested on GPT-5.5 Low)
2. Run a basic task (e.g., read some files and follow instructions)
3. Check session usage after the task completes
4. Usage consumed is significantly higher than expected for the task

What is the expected behavior?
