OpenAI, Anthropic PBC and SpaceXAI were hit by service outages on Thursday, Bloomberg Technology reports, citing user reports and company status pages. The disruptions affected customers of three major US AI model makers. The clearest detail in the provided reporting is on OpenAI. According to Bloomberg, tens of thousands of users reported OpenAI service issues on Downdetector, the outage-tracking service. OpenAI said it was investigating elevated error rates across ChatGPT and Codex, Bloomberg reports. ChatGPT is OpenAI’s consumer and enterprise chatbot product, while Codex is its AI coding tool. The Bloomberg item also names Anthropic PBC and SpaceXAI as affected, but the feed material does not provide the same level of detail on the scope, duration or specific services involved for those two companies. The story is therefore best read as a confirmed multi-provider outage report with limited public detail beyond OpenAI’s named products and error-rate investigation. Who benefits: Providers with resilient infrastructure and clear incident communications can use reliability as a differentiator. Customers with multi-provider or fallback setups are better positioned during service interruptions. Who's exposed: Teams that depend heavily on a single hosted model provider for customer support, coding or internal workflows are most exposed. The provided reporting does not establish how long the outages lasted or which customer segments were most affected.
