Training Data: A Foundation Built on Diversity and Complexity

The training regime of Kyle is a testament to the diversity and complexity of the data it was exposed to. The model's foundation is built upon a dataset that encompasses a wide array of ragdoll movements, each enriched with visual inputs and memory components. This rich dataset ensures that Kyle can simulate real-world scenarios with remarkable effectiveness, allowing it to understand and predict physical interactions in a dynamic environment.

The current iteration of Kyle has been trained through a sequence of 20 million steps, a journey that has imbued it with the finesse to handle a multitude of tasks. As we continue to evolve our training scenes, we plan to release additional sequences. These will serve as building blocks that can be combined to forge new models, each specializing in different fitness applications, from the delicate balance required for acrobatics to the precision needed for sorting tasks.
