Notion restored access to Anthropic models in its AI product after a service disruption forced the company to temporarily disable Claude across the platform.

The outage began after Notion detected degraded performance on Anthropic’s Opus 4.7 and 4.8 models, which caused a higher rate of failures for users selecting those models in Notion AI. The company responded by turning off access to all Anthropic models while it worked to maintain service stability.

Access was restored roughly 12 hours later, according to Notion Head of Product Max Schoening. He said the disruption was a temporary service issue and pushed back against suggestions that the incident reflected broader model quality problems.

Anthropic said a brief infrastructure issue caused elevated errors across multiple Claude models and that the problem has since been resolved.

The incident highlights a growing risk for companies building AI features on top of third party model providers. Notion can control its product layer, routing, and user experience, but it still depends on external infrastructure for core AI performance.
