A bug report opened last week for OpenAI's Codex coding agent warns that "Codex SQLite feedback logs can write ~640 TB/year and rapidly consume SSD endurance #28224." Developer Rui Fan reported that on his machine, after about 21 days of uptime, the main SSD had written about 37 TB, extrapolating to roughly 640 TB/year. On a 1 TB SSD, that is about 640 full-drive writes per year, potentially consuming a full drive's warranted write endurance in less than a year. Another developer cited a Codex-generated estimate that "this regression plausibly burned low-single-digit millions of dollars of SSD endurance across users during the March-June Window," assuming a cost of $0.13 per TB written to SSDs. The issue involves local diagnostic logging, introduced around the time the app debuted last year and on by default, which stays on the device unless included in a feedback report. A spokesperson for OpenAI confirmed that company engineers are aware of the problem.
