At commit 204698b45b3712590f06245fbfba32d3be539812 the README says 'the majority of V-JEPA 2 is licensed under MIT' with three Apache-2.0 source files and says nothing about checkpoints. Weights are hosted two ways: dl.fbaipublicfiles.com URLs listed in the README (including V-JEPA 2-AC, a 11.76 GB object; HEAD only, not downloaded) and 8 Hugging Face repos whose card front-matter says 'mit' for six and 'apache-2.0' for the two ViT-g fpc64 pretrained cards; the cards contain no licence prose and the HF repos list no LICENSE file. V-JEPA 2-AC is not in the HF collection. The paper (arXiv v1) says it trained V-JEPA 2-AC on under 62 hours of Droid robot video and pretrained on public datasets including YT-Temporal-1B; rights of that data are not addressed in the texts read. Terms for outputs, redistribution and training use of the weights: not stated.
