The Model Factory. The system behind the models. Traditional foundation model training is manual, linear, and slow. We built something different.

The Model Factory is Poolside's internal platform for training, scaling, and experimenting with foundation models. It handles automated evaluation during training, reinforcement learning from code execution, architecture ablations, synthetic data generation, and data mixing—all orchestrated across our GPU clusters.

Experiments that used to take weeks to schedule now run in under an hour. We describe a configuration, and the Factory handles the rest.
