At the dated text 'Last Modified / Version Release Date: October 24, 2025' the agreement has 11 numbered sections. It grants a perpetual, worldwide, no-charge, revocable licence to use, modify, make derivatives of, sell and distribute the Model; allows redistribution with a copy of the agreement and a Notice line; requires 'Built on NVIDIA Cosmos' for Cosmos Models in several uses (including training another AI model with them or their outputs); states NVIDIA claims no ownership of outputs; and ends your rights automatically on litigation or on bypassing a Guardrail without a substantially similar one. It has no clause on hosting as a service by that name, no express patent licence (the word 'patent' appears only in the litigation-termination sentence) and no operative commercial-use clause beyond the preamble statement. This is a reading of text, not legal advice.

Curator qualifications: Preamble: 'Models are commercially usable.' Section 2 (line 28): 'NVIDIA hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, revocable (as stated in Section 2.1) license to publicly perform, publicly display, reproduce, use, create derivative works of, make, have made, sell, offer for sale, distribute (through multiple tiers of distribution) and import the Model.' Section 2.1: licences end 'If You institute copyright or patent litigation ...'. 'commercially usable' occurs once. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: [rights_conflict_record] eligible_after_conflict_narrowing

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
