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 23 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/oxen: open an issue to ask a question, or submit a pull request to add artifacts.
