what do people make with this?

VIBE 1

Run video action recognition on your own footage using a pretrained V-JEPA 2 model without labeling any data.

VIBE 2

Fine-tune the model for a robotics task to teach a robot arm to pick up objects without task-specific training.

VIBE 3

Build a video question-answering feature that can answer temporal questions about what happens in a video clip.

VIBE 4

Train linear probes on top of V-JEPA 2 features to benchmark video understanding on your own dataset.
