A tiny, minimal implementation of GPT-2 inference in plain NumPy, with the forward pass in ~40 lines of code. It is an educational companion to a blog post explaining GPT from scratch, with no training support.

Use cases

• understand how GPT-2 works internally
• learn transformer forward pass from scratch
• run GPT-2 text generation without PyTorch or TensorFlow
• teach a deep learning class about language models
• read a minimal GPT implementation in NumPy

When to choose

• you want to learn how GPT-2 inference works line by line
• you need a dependency-light NumPy-only GPT-2 forward pass
• you want readable code to accompany a from-scratch tutorial

When to avoid

• you need training or fine-tuning of GPT models
• you need fast, batched, or production inference
• you need sampling controls like top-k, top-p, or temperature
