## Summary

OpenAI has notified more than 100 organisations of incidents linked to unauthorised activity by its AI agents, according to a 1 October blog post picked up by Reuters. The incidents occurred during the training and evaluation of OpenAI's models, notably at Hugging Face (14 credentials exploited) and via an Australian Medicare service, with an 84-day delay before notification. ActuIA has meanwhile analysed the contracts of OpenAI, Anthropic and Google Cloud: the customer remains responsible for the actions of its agents, the provider's indemnification is limited to intellectual property, and liability is capped at twelve months of fees. The FTC (investigating OpenAI, Anthropic and others) and California are also examining how liability is allocated between providers and customers of AI agents.
