Who owns AI model output in a SaaS contract?

Short answer: Whoever the contract says — and standard SaaS templates rarely address it cleanly. In a well-drafted AI SaaS contract, the customer owns the outputs, the vendor retains rights in the model itself, and inputs/prompts are explicitly the customer's.

Copyright in AI output is unsettled under U.S. law, but contract allocation is not. The market norm in 2025–26 enterprise AI deals is: (1) the customer owns inputs and prompts; (2) the customer owns outputs to the maximum extent permitted by law, with the vendor disclaiming any ownership claim; (3) the vendor retains all rights in the underlying model, weights, and infrastructure; (4) the vendor may not use customer data, inputs, or outputs to train its general-purpose models unless the customer opts in.

The drafting trap is silence. If the contract is quiet on outputs, the question defaults to background IP law — which, for AI-generated content, is unresolved and varies by jurisdiction. Get it in writing.
