Notion temporarily suspended the use of Anthropic models in Notion AI over the weekend due to a temporary performance degradation in some models, leading to an increased failure rate for user calls. Several hours later, both parties stated that the issue had been resolved and access had been restored.

Faults lead to increased failure rates

Notion stated in a status update earlier Sunday that the Opus 4.7 and 4.8 models of Anthropic were experiencing performance degradation, with users choosing these models encountering a higher failure rate. As a result, Notion has temporarily disabled all Anthropic models in its tools.

Notion denies quality controversy

Approximately 12 hours later, Max Schoening, Notion's product lead, stated that interpreting the incident as a model quality issue was inaccurate. He explained that it was a temporary service outage, and similar incidents could occur with services such as Notion, GitHub, and AWS.

He later confirmed that access to the Anthropic model in Notion had been restored.

Anthropic says it has fixed the issue.

An Anthropic spokesperson stated that a brief infrastructure outage caused an increase in errors across multiple Claude models for a period of time. The company said the issue has since been resolved and service has been restored.

This outage also reflects the continued high dependence of AI applications on underlying model services. Any fluctuations on the model side or infrastructure side will directly impact the availability of upper-layer products.
