What Oxen is

Oxen.ai combines access to AI models with infrastructure for organizing, versioning, collaborating on, and customizing their data. A unified API provides access to more than 200 text, image, video, and audio models. Oxen versions prompts, media, labels, metadata, generated outputs, and training examples, and says it scales to millions of files and terabytes of data. Teams can browse datasets, review generated results, experiment across branches, and track who changed what and when. Users can fine-tune supported open-source models on proprietary text, image, and video datasets. Data can be read or written through the Python API, HTTP API, command line, or open-source server. Oxen offers private deployments in a customer’s VPC or fully on-premises. The free Explorer plan includes unlimited public repositories and collaborators, alongside limits on private repositories, collaborators, storage, and transfer. Hacker costs $30 a month and Pro costs $60 a month. Model inference is pay as you go, with no upfront cost or subscription required; dedicated GPU use is charged per second.
