Simply upload your data, and we will provision GPU infrastructure to execute the training process, then save the fine-tuned model weights directly to your repository. Model weights and datasets are versioned so that you can always track the data that was used to train the model. Fine-Tuning Ox Once the fine-tuning process is complete, you can deploy the model and start using it in your application.
If you are looking for a more hands-on approach to fine-tuning, you can write your own code in Notebooks.

​
Why Fine-Tune?

Fine-tuning is a great tool to reach for when basic prompting and context engineering fall short. You may need to fine-tune when:
  • Quality is critical and the model isn’t consistently producing correct outputs.
  • Proprietary Data gives you a unique advantage that generic models can’t capture.
  • Latency is a deal breaker and you need real-time responses.
  • Throughput limitations are bottlenecking your application’s scalability.
  • Ownership of the model is important and you want to control your own destiny.
  • Cost if a foundation model is too expensive for your use case or you want to deploy a smaller model to the edge.
With Oxen.ai, we make it easy to automate the fine-tuning process of LLMs on your own data.

Examples

Here are specific examples of how fine-tuning can be used to solve real-world problems. From coding agents to opitmizing tool calling for your agent, there are a lot of use cases for fine-tuning.

​
Start by Uploading a Dataset

To get started, you’ll need to create a new repository on Oxen.ai. Once you’ve created a repository, you can upload your data. The dataset can be in any tabular format including csv, jsonl, or parquet. Fine-Tuning Dataset Upload Once you have your dataset uploaded, you can query, explore, and make sure that the data is high quality before kicking off the fine-tuning process. Your model will only be as good as the data you train it on. Fine-Tuning Dataset When you feel confident that your dataset is ready, use the “Actions” button to select the model you want to fine-tune. Fine-Tuning Dataset

​
Selecting a Model

This will take you to a form where you can select the model you want to fine-tune and the columns you want to use for the fine-tuning process. Right now we support fine-tuning for prompt/response single-turn chat pairs. Fine-Tuning Model Selection
If you want support for any larger models or modalities like text-to-image, contact us. We are actively working on support for different data formats and distributed training.

​
Monitoring the Fine-Tune

Once you have started the fine-tuning process, you can monitor its progress. The dashboard will show you loss over time, token accuracy, the learning rate, and number of tokens processed. Fine-Tuning Monitoring Click on the “Configuration” tab to see the fine-tuning configuration. This will include a link to the dataset version you used and the raw model weights. It will show you the pricing for the fine-tuning process as well.

​
Deploying the Model

Once the model is fine-tuned, you can deploy it to a hosted endpoint. This will give you a /chat/completions endpoint that you can use to test out the model. Fine-Tuning Configuration Swap out the model name with the name of the model you want to use. 
curl https://hub.oxen.ai/api/chat/completions -H "Content-Type: application/json" -d '{
    "model":"oxenai:my-model-name",
    "messages": [{"role": "user", "content": "What is the best name for a friendly ox?"}],
}'

​
Chatting with the Model

Once the model is deployed, you can also chat with it using the Oxen.ai chat interface. Learn more about the chat interface here. Chatting with the Model

​
Downloading the Model Weights

If you want access to the raw model weights, you can download them from the repository using the Oxen.ai Python Library or the CLI. Follow the instructions for installing oxen if you haven’t already.

Need Custom Infrastructure?

If you need custom or private deployments in your own VPC or want to train a larger model on distributed infrastructure, contact us and we can give you a custom deployment.
