AI vendors
Anthropic, OpenAI and OpenRouter are used only by Fly.io’s internal tooling, under our AI usage policy. We never send the contents of your volumes, or the bodies of requests to your applications, to an AI vendor. OpenRouter routes a request to a third-party model provider; our policy limits its internal use to providers whose terms prohibit training on the content, and OpenRouter itself does not train on inputs or outputs.
During support and abuse investigations, the data that can be processed is account and organization metadata, support ticket text, and platform log lines, which include whatever your application writes to stdout. For Managed Postgres, our support tooling can also process a cluster’s Postgres logs and, when a Fly.io operator runs a read-only diagnostic query during an investigation, the results of that query.
