Train a GPT from scratch in the browser

Train a GPT from Scratch in the Browser is an educational tool that explain how GPT models work by allowing users to build, train, and run their own transformer-based language models entirely within a web browser. Inspired by Andrej Karpathy's microGPT project, this tool eliminates the need for local machine learning infrastructure, making deep learning accessible to beginners and students without requiring GPU resources or complex setup processes. Users can understand the fundamentals of neural networks, attention mechanisms, and language model training through hands-on experimentation. The tool is particularly valuable for educators, students, and AI enthusiasts who want to learn how transformer architectures function at a practical level rather than just theoretically.
