Overview
Ludwig is an open-source, low-code framework designed to simplify the process of building and training custom AI models, including large language models (LLMs) and other deep neural networks. It provides a declarative configuration approach, allowing users to define models without extensive coding. The tool supports a variety of data types and integrates with popular ML libraries like TensorFlow and PyTorch.
Problem It Solves
It reduces the complexity and time required to develop custom AI models by abstracting away much of the boilerplate code and infrastructure setup.
Target Audience: Developers and teams working with developer tools automation.
