Oxen

Oxen.ai is a blazing-fast data version control system and AI platform for teams building with their own data. Its open-source Rust core (liboxen) versions, branches, and shares terabyte-scale datasets, model weights, and experiments without Git's large-file limits. On top of the version control layer, Oxen.ai offers a unified, OpenAI-compatible inference API across 200+ text, image, video, and audio models, plus a fine-tuning API for training and deploying custom LLMs, vision-language, image, and video models. Developers work through a Python SDK (oxenai), a command-line tool (oxen), and an HTTP API for repository management, workspaces, data-frame diffing, generation queues, and model deployment.

Oxen publishes 19 APIs on the APIs.io network, including Ai API, Branches API, Commits API, and 16 more. Tagged areas include Company, Data Version Control, Machine Learning, Artificial Intelligence, and Fine-Tuning.

Oxen’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 22 more developer resources.
