Oxen.ai

What is Oxen.ai?

Oxen.ai is a platform for building AI on your own data. It gives developers one API to run text, image, video and audio models from many labs, with chat completions, image generation and editing, and video generation endpoints that work with the OpenAI SDK by changing the base URL. Prompts, reference images, generations and training data are stored in collaborative repositories built on the open source Oxen version control system, so teams can branch experiments, track who changed what, and fine-tune open models on proprietary datasets. Data is reachable through a Python API, an HTTP API, the command line or an open source server, and private deployments in a VPC or on-prem are available on request. Pricing is pay as you go per model, per second of GPU time and per second of fine-tuning, with no subscription required for model usage.

Use cases

• Call many AI models through one API
• Version prompts, images and training data
• Fine-tune open models on private datasets
• Generate images and video from prompts
• Deploy a custom model to a dedicated GPU
• Collaborate on datasets across a team
• Track experiments across branches

Who it's for

• Machine learning engineers
• Developers
• AI product teams
• Creators

Why use Oxen.ai

• Switch between hundreds of models without integrating each provider separately.
• Keep prompts, outputs and training data in one versioned repository for audit and reproducibility.
• Fine-tune open models on your own data and deploy them to a dedicated GPU.
• Pay only for what you run: model calls have no upfront cost or subscription.
• Build on an open source version control system rather than a closed data store.

Oxen.ai features

• Unified inference API for text, image, video and audio models
• OpenAI SDK compatibility through a custom base URL
• Async queue for image and video generation
• Git-like version control for large datasets
• Fine-tuning with LoRA and full fine-tune options on supported models
• Dedicated GPU instances billed per second
• Python API, HTTP API and command line access
• Private deployments in a VPC or on-prem
• Collaborative repositories with change history

How to get started with Oxen.ai

1. Create an account and generate an API key in your settings.
2. Browse the model list and call a model through the inference API or the OpenAI SDK.
3. Save prompts, references and generated outputs into a repository for versioning.
4. Fine-tune an open model on your dataset, billed per second of training time.
5. Deploy the tuned model to a dedicated GPU and call it through the same API.

Oxen.ai limitations

• Per-model prices vary by model, modality and quality tier
• Dedicated GPUs shut down automatically after 15 minutes of inactivity
• Private VPC or on-prem deployments are arranged by contacting the vendor
