  You've seen openai/gpt-2.
  
  You've seen karpathy/minGPT.
  
  You've even seen karpathy/nanoGPT!
  
  But have you seen picoGPT??!?
  
  `picoGPT` is an unnecessarily tiny and minimal implementation of GPT-2 in plain NumPy. The entire forward pass code is 40 lines of code.

  # PicoGPT: An Educational, NumPy-only GPT-2 Implementation
  
  PicoGPT is an educational, extremely minimal implementation of GPT-2, built entirely in plain NumPy. It's designed to help you understand the core mechanics of GPT-2 with the fewest lines of code possible, making it a perfect companion for learning about large language models from scratch.

  ## Comparison to other minimal GPT implementations
  While projects like `karpathy/minGPT` and `karpathy/nanoGPT` offer excellent minimal GPT implementations, `picoGPT` distinguishes itself by being an even more stripped-down, single-file (or very few files) implementation built *entirely in plain NumPy*. This makes it uniquely suited for deep dives into the core mechanics of GPT-2 without external deep learning frameworks, prioritizing educational clarity and extreme conciseness.
