 | I’ve been building an interactive 3D + 2D visualization of GPT-2. You can check it out at: It displays real activations and attention scores extracted from GPT-2 Small (124M) during a forward pass. The goal is to make it easier to learn how LLMs work by showing what is happening inside the model. The 3D part is built with Three.js, and the 2D part is built with plain HTML/CSS/JS. Would love to hear your thoughts or feedback! [link] [comments] |
