Notion says about 1% of its customers were affected, including Insights chat inputs and model outputs.

Fireworks AI confirmed an attacker breached its cloud provider and reached a development system, taking customer billing information and some datasets.

On November 3, Notion disconnected from Fireworks, deleted stored data, and stopped connectivity.
