We felt bad about the slowdowns as we were adding GPUs, so we reset everyone's limits to make up for it:

Currently serving gpt-5-codex at degraded speeds, about 2X, due to the very high demand. We are finding GPUs left and right to match demand, we'll keep you posted

Demand for GPT-5-Codex is higher than forecasted and we need to stand up more GPUs! In the meantime Codex is running 2x slower than targets. Working on fixing this ASAP

We have reset everyone's limits for gpt-5-codex to allow you all to benefit more from it today and as a way to make up for the slowdowns earlier while we were provisioning additional GPUs. We'll continue to add capacity throughout the week to maintain the speed. Enjoy!
