An interactive spreadsheet (Excel/Numbers) that implements the full nanoGPT inference pipeline, including embedding, layer norm, self-attention, MLP, and softmax, with roughly 85,000 parameters. It is a visual educational tool for understanding transformer internals through fully configurable matrix calculations.

Use cases

• visualize how a transformer processes data step by step
• understand self-attention with interactive matrix calculations
• learn GPT architecture without writing Python code
• experiment with transformer parameters in a spreadsheet
• teach deep learning concepts with a hands-on tool
• explore nanoGPT's inference pipeline interactively

When to choose

• you are a visual learner trying to understand transformer internals
• you want an interactive, configurable walkthrough of GPT mechanisms
• you want to teach or self-study how self-attention and MLPs work
• you prefer spreadsheets over code for exploring calculations

When to avoid

• you need actual trained weights or correct inference outputs
• you want to train or fine-tune a language model
• you need production-grade LLM inference performance
• you expect large-scale tokenization beyond the A/B/C character demo
