Notion faced a service disruption this past weekend affecting its integration with Anthropic's AI models, specifically Opus versions 4.7 and 4.8. Early Sunday morning, Notion announced that users were experiencing degraded performance, leading to a higher rate of failures when selecting these models. Consequently, the company decided to disable all Anthropic models in its automated productivity tool. Twelve hours later, Max Schoening, Notion's head of product, expressed surprise at the social media response, noting that the situation was a temporary service disruption, common to many tech platforms. He reassured users that access to Anthropic's models had been restored. In a statement, an Anthropic spokesperson confirmed that a brief infrastructure issue had caused elevated errors across multiple Claude models but emphasized that the problem had been resolved. Both companies expressed gratitude for user patience during the incident, highlighting the importance of reliability in AI service integrations.
