Anthropic confirms Claude is down, multiple models affected

A global AI outage has struck one of the most powerful language models, leaving millions of users without access to its services. On September 3, 2026, Anthropic confirmed that its popular Claude model was experiencing an outage, with multiple models affected and requests failing to complete or returning errors.

The incident began at around 9:41 AM ET, when users started reporting issues with the company’s latest Mythos, Fable, and Opus models. At first, the extent of the outage was unclear, but Anthropic soon confirmed that several Claude models were impacted, including Mythos/Fable 5.1, Mythos/Fable 5, Opus 5, Opus 4.8, and Opus 4.6.

For those unfamiliar with AI models like Claude, they are essentially software programs designed to generate human-like text based on user input. These models can be used for a wide range of tasks, from content creation and translation to customer service chatbots and more. The fact that multiple models were affected by the outage suggests that there may have been a deeper issue with Anthropic’s infrastructure or architecture.

As the outage continued into the afternoon, users took to social media to express their frustration and disappointment at being unable to access their favorite AI-powered services. Meanwhile, Anthropic’s status page remained updated in real-time, providing users with regular updates on the progress of the fix. At 10:49 AM ET, the company announced that it was continuing to work on a solution, but the outage remains ongoing as of this writing.

The impact of the outage extends beyond just inconvenience; for businesses and organizations relying on Claude for critical tasks, the downtime could have significant financial implications. As AI becomes increasingly integrated into our daily lives, outages like these serve as a reminder that even the most advanced technology is not immune to errors or security threats.

In practical terms, users affected by the outage should be prepared for potential delays or disruptions in their services. If you rely on Claude for work or other critical tasks, it’s essential to have contingency plans in place, such as alternative AI models or manual processes to mitigate any downtime.

Ultimately, the outage serves as a reminder of the importance of robust infrastructure and security measures in the AI space. As we continue to push the boundaries of what’s possible with artificial intelligence, we must also prioritize the reliability and resilience of these systems to ensure they can withstand unexpected events like this one.
