Notion recently restored access to Anthropic’s models following a weekend service disruption that caused degraded performance for users of certain AI models, resulting in higher failure rates.

In an update posted on Sunday morning, Notion stated that the issue was due to ‘degraded performance’ with Anthropic’s Opus 4.7 and 4.8 models, leading them to disable use of all Anthropic models until the service stabilized.

Notion's head of product, Max Schoening, expressed surprise at the number of retweets his post received, stating that such issues are common in the tech industry, comparing Notion’s own services and even more established platforms like GitHub and AWS to experiencing similar hiccups. He also noted that the issue had been resolved by mid-afternoon on Sunday.

An Anthropic spokesperson provided a statement acknowledging a brief infrastructure issue that caused elevated errors across multiple Claude models for a short period, but assured users of their gratitude for patience while they worked to resolve the issue.
