What's New in Illustrate GPT
1.1
October 3, 2026
A complete redesign into an interactive course on how GPT works: • 8 hands-on chapters: Tokens, Embeddings, Attention, Layers, Sampling, The Loop and a Quiz • Words colored by confidence. Tap any word to see the alternatives and rewrite the story from there • Attention explorer with all 36 heads and automatically detected head roles • Logit lens: watch the prediction form layer by layer • Sampling lab with live temperature, top-k and top-p • Rebuilt on Apple's MLX: much faster generation with a KV cache, and a working Stop button • Smaller download and lower memory use
