At YuE 1647252d, MODEL_LICENSE licenses the three YuE2 checkpoints under CC BY-NC 4.0 with a dated (2026-09-16) additional permission for individual creators to generate and monetise outputs under responsible-use conditions; it excludes code/tokenizer/evaluation assets from its scope, denies commercial redistribution or sale of weights, and directs companies to a commercial licence. This fills the MODEL_LICENSE gap recorded by L07 for C2-B04-H-12.

Curator qualifications: Training, hosting and API use are not mentioned (producer F4 confirmed by absence in text read; no inference of permission). Earlier YuE (YuE-s1) Apache-2.0 release generations remain distinct; do not collapse into a conflict (per L07 H-12 correction). Training-data provenance for the weights is not addressed by this file. No legal conclusion; per-use applicability (hosting, training, API) not determined from text. Licence/code text only; no weights, checkpoints or audio downloaded; nothing run.

Limitations: Licence/code text only; no weights, checkpoints or audio downloaded; nothing run.

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