Their words · Terms of Service

“ d. Customer Key Usage Responsibility : If the customer chooses to use their own generative AI model API key instead of Glean's Azure OpenAI/OpenAI key, they are responsible for negotiating and adhering to the terms of usage, training, and retention with their model provide directly. In this scenario, Glean will not be responsible for managing any relationship between the customer and the generative AI model provider or for any terms and conditions agreed upon by the customer and the provider (i.e. no Glean guarantee on zero day data retention and no training on customer data, etc. by Azure OpenAI or OpenAI).”
