Codex Sol suddenly burning through my weekly limit much faster after reset — anyone else seeing this?

I’m on ChatGPT Pro 5x and I use Codex quite heavily for software development, so I’ve gotten pretty familiar with how quickly my weekly allowance normally drops.

After my latest weekly reset, something seems to have changed dramatically.

Using Sol, I burned through roughly 7–8% of my main Codex weekly allowance in less than one hour.

Before the reset, with comparable development workloads on Sol, that same percentage would normally last me several hours — sometimes close to half a working day.

I contacted OpenAI support.

The first response got distracted by my separate GPT-5.3-Codex-Spark bucket being exhausted, but I clarified that Spark has absolutely nothing to do with the issue.

Support then confirmed:

• My main Codex weekly allowance was already at 8% used / 92% remaining
• The Spark allowance is a completely separate bucket
• Their AI support agent cannot access per-request/session usage logs to explain what actually consumed that 8%
• Usage can vary based on tokens, context size, Fast mode, tool calls, etc.

I understand all of that. I’m not comparing “one hour of Codex” as if usage were time-based.

I’m comparing my own Sol usage before and after the weekly reset, doing broadly comparable work, and the difference is large enough that I noticed it almost immediately.

I asked them specifically whether anything changed regarding:

• Sol metering
• the effective weekly allowance
• usage multipliers
• account-side calculation
• duplicated/abnormal metering

The case has now been escalated to a support specialist.

I’m curious whether other heavy Codex users have noticed the same thing after their most recent weekly reset.

Especially interested in reports from people using Sol on Pro / Pro 5x, rather than Spark.

Did your weekly percentage suddenly start dropping much faster too?
