Requires Expertise

You can use River AI to train and own personalized AI models through LoRA fine-tuning and reinforcement learning on open-source models ranging from 35B to 1T parameters. It lets you bring your own data, shape model weights, and deploy custom agents for specific tasks via a Python client. The goal is to give individuals full ownership of their AI — including the hardware it runs on, the data it learns from, and the resulting model weights.
