Substratus is an AI tool that allows users to build, train, and deploy state-of-the-art machine learning models across different cloud providers. With Substratus, users can quickly and easily deploy cutting-edge open-source LLMs (Large Language Models) in just minutes, without the need for complex setup or infrastructure management.The tool offers prepackaged container images that enable the import of popular state-of-the-art models. Once imported, users can launch remote notebooks to easily dive into the code. Substratus simplifies the fine-tuning process by handling the heavy-lifting of model refinement on suitable hardware. Users can select an off-the-shelf model, register a training dataset, and let Substratus take care of the rest.At the core of Substratus is its integration with Kubernetes, leveraging its controllers to orchestrate all machine learning operations. From importing datasets to model training and serving, Kubernetes ensures seamless execution across multiple environments with minimal dependencies. Substratus can be deployed anywhere Kubernetes runs, providing flexibility and scalability.To assist users in getting started, Substratus offers comprehensive documentation, including an introduction and quickstart guide. Additionally, a vibrant community is available for support through platforms such as Stack Overflow and Discord.Substratus is designed to accelerate the development and deployment of AI models, enabling users to focus more on their data and less on the infrastructure and complexities of machine learning operations.
