Meta expanded the Meta Model API Terms of Service to introduce tiered service models (Discounted and Standard Models), added expanded definitions of Inputs to include libraries, code, and databases accessed through connectors, clarified intellectual property ownership between parties, and added explicit AI disclosure and labeling obligations for developers. The terms now specify that developers must comply with applicable AI classification and provenance-marking requirements when deploying outputs to end users, and introduced new license restrictions governing downloadable materials and third-party software included in the services.
Developers: If your jurisdiction requires you to tell users that content is AI-generated or AI-assisted, you must implement that labeling in your product.
Developers: You can now submit code, databases, and connected data to Meta's API, and Meta may use this content for safety and product improvement purposes as stated in the terms.
Developers: Downloadable tools may include open source software; you must comply with those open source licenses in addition to Meta's terms.
Developers: You cannot redistribute or modify downloadable tools; you can only use them as Meta provides them.
The updated terms establish new obligations for developers integrating Meta's AI models into their products. The agreement now requires developers to comply with applicable AI labeling, disclosure, provenance-marking, and system classification requirements under applicable law, with responsibility falling on the developer to implement these disclosures to end users. The expanded definition of Inputs now explicitly includes code, libraries, databases, and any content accessed through connectors or integrations, which may broaden what user-submitted content Meta claims the right to process for safety and security purposes.
→ Review whether your integrated products using Meta's API models currently implement AI-generated content disclosures; assess applicable AI transparency requirements in your jurisdictions.
→ Audit current data submissions to Meta's API to confirm they comply with the expanded definition of Inputs, including code, libraries, and connected data.
→ Review any downloadable tools or materials you use from Meta's API against embedded third-party open source licenses to confirm your usage complies.
