## What it is
Official PyTorch codebase and pretrained models for V-JEPA 2, a self-supervised video encoder trained on internet-scale video, plus V-JEPA 2-AC, an action-conditioned latent world model for robot manipulation. It provides training recipes, model weights, and evaluation code for video understanding, prediction, and planning tasks.

## Use cases
- extract video features for action recognition
- anticipate human actions from video
- train a self-supervised video encoder
- run a robot manipulation policy zero-shot
- fine-tune video models on downstream tasks
- predict future video latents with a world model

## When to choose
- you need state-of-the-art video understanding features in PyTorch
- you want to experiment with self-supervised video pretraining
- you need a video world model for robot planning without task-specific training

## When to avoid
- you need a lightweight production video pipeline rather than research models
- you lack GPU resources for large vision transformers
- you need a general-purpose video editing or playback tool
