Transformer Explainer
Transformer Explainer is an interactive visualization tool that runs a live GPT-2 model in the browser to demonstrate the internal operations of Transformer-based AI models.
Transformer Explainer is an interactive visualization tool created by researchers at the Georgia Institute of Technology to help users understand how Transformer-based models like GPT function. It operates by running a live GPT-2 model directly in a web browser, enabling users to input their own text and observe the internal components and operations in real time. The interface allows users to track how these components work together to predict the next tokens in a sequence. It serves as an educational resource for individuals interested in the mechanics of text-generative models. The tool is open source and available under the MIT License.
