The article introduces Petals, a project that allows users to run large language models at home in a decentralized manner, similar to BitTorrent. Users can load a part of the model and join a network of people serving its other parts, enabling tasks like text generation and fine-tuning. The project aims to provide a flexible and decentralized alternative to traditional cloud-based language model APIs. Petals is designed for ML researchers and engineers, and it does not involve cryptocurrency or blockchain incentives.
