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.

Meta added a 'Contact us' link to the header of their Llama API Terms of Service, detected on July 22, 2026. The substantive governance language of the terms—covering access to services during a limited preview period—remains unchanged. This is a formatting or navigation modification to the document structure, not a change to the rights, obligations, or operational rules governing API use.

Meta rebranded its Llama API service to 'Meta Model API' and restructured the terms significantly. The updated agreement expands the scope from Llama-specific models to broader 'Meta Models', removes the 700 million monthly active user restriction that previously barred large platforms, eliminates the EU prohibition on multimodal AI access, and removes fine-tuning functionality language while adding new provisions around managed accounts and data processing. The operational effect is broader developer access without scale restrictions and simplified account management, offset by removal of specific Llama model carve-outs and fine-tuning documentation.

Meta updated the release date format in the Llama API Terms of Service header on July 7, 2026. The previous version stated 'Release Date: April 29, 2025' with a comma after the date; the updated version removes the comma, changing it to 'Release Date: April 29 2025'. This is a minor formatting correction with no operational impact on the substantive terms, conditions, or obligations in the agreement.

Meta updated its Llama API Terms of Service on May 29, 2026, making a minor stylistic change to a sentence describing when Meta may retain user content. The updated version removes the word 'and' before clause (ii), changing a list structure from semicolon-and-semicolon-and to semicolon-semicolon-and formatting. This is a grammatical adjustment with no operational change to Meta's content retention authority or user obligations.

Meta updated its Llama API Terms of Service on May 21, 2026 to add a third reason it may retain user content. Previously, Meta stated it could retain content for legal compliance and to exercise its rights under the agreement. The updated terms now add that Meta may also retain content when its systems flag data for a potential policy violation. This expands the circumstances under which content may be kept beyond what was previously disclosed.

Meta removed the 'Llama API Service status: Available' line and 'Contact us' text from the header of its Llama API Terms of Service on May 15, 2026. The Terms themselves remain substantively unchanged. This is a formatting and header reorganization with no change to the actual contractual obligations, rights, or operational requirements.
