The last 30 days have been some of the hardest for most Codex users to comprehend.

One day, they were using a frontier model (even if it was relatively expensive usage-wise), getting more usage resets than they knew what to do with, and generally content besides the usual 5-hour-limit grumbling on Plus plans.

Then Opus 5.5 dropped. Not only is it on par with Astra, but it is also, anecdotally, 10x as efficient.

Well, as most Codex users usually see it, there was nothing to FOMO over. Just a matter of time before the next top-tier, dirt-cheap model dropped from OpenAI. And OpenAI’s social accounts kept hyping up the next model.
