This organization is a synthetic data spring for video reasoning. It hosts the parameterized generators behind VBVR (Very Big Video Reasoning) — each one capable of producing unlimited training data on demand.

Every repository is a self-contained task generator: give it a seed and parameters, and it deterministically produces (first frame, prompt, final frame, ground-truth video) tuples. There is no fixed dataset size — every generator can mint fresh, unique samples indefinitely. Need 10K examples? 10M? Just run the generator longer.

Generator(seed, params)  ->  first_frame.png, prompt.txt, final_frame.png, ground_truth.mp4

150 generators are open-source today, organized across five cognitive categories — with more on the way.

Extraction of structured representations from sensory input.

Distillation of generalizable knowledge from particular experiences.

Manipulation and synthesis of mental representations.

Propositional truths, either learned or innate.

Representation of places and geometric relationships.
