OpenAI's ChatGPT has experienced several minor service disruptions in recent weeks, including elevated error rates across ChatGPT, Codex, and APIs on September 29 that resolved the same day, plus login and performance issues on October 1 lasting under an hour. These incidents reflect ongoing challenges scaling large language model infrastructure amid rapid user growth and feature expansions, such as the new "Dots" AI assistant unveiled at the company's developer conference. With 99 incidents logged over the past 90 days—14 rated major or critical—traders monitor load spikes, API demand, and any unannounced model updates that could trigger further downtime. No major outages have occurred in the immediate past 48 hours, though high-traffic periods remain key swing factors.
