Compression and LLMs Share a Core: Data Prediction
Sexton's framing positions LLM training as a form of compression, which reframes how the industry talks about model efficiency and data redundancy as two sides of the same information-theoretic coin.

GIGAZINE highlights a blog post by ngrok developer educator Annie Sexton arguing that data compression and large language models solve the same underlying problem: predicting data. Both fields reduce redundancy and seek efficient representations, connected through entropy in information theory. The piece breaks down compression basics like minification and run-length encoding, then maps them to the structure of modern tools such as gzip and Brotli.
Annie Sexton, a developer educator at ngrok, published a blog post titled "Compression is prediction" that draws a direct line between file compression and large language models. Both, she argues, are exercises in data prediction that reduce redundancy and aim for more efficient representations, tied together by the mathematical framework of entropy.
The post walks through the basics of compression to make the connection concrete. Minification strips code down to machine-parseable essentials, while run-length encoding turns strings like "AAAAAAAAAABBBBBCCDAAADDDDD" into shorter token counts such as "A9B4C2D1A3D9." Modern tools like gzip and Brotli then rely on three components: transform, model, and entropy coder.
The model passes symbol probabilities to the entropy coder, which produces the final compressed bitstream. That pipeline, Sexton argues, is where the overlap with LLMs becomes visible, since both systems are ultimately guessing what comes next in a sequence of data.
