What Is ChatGPT Doing ... and Why Does It Work? by Stephen Wolfram Summary
Overview of What Is ChatGPT Doing ... and Why Does It Work?
Stephen Wolfram demystifies AI's most revolutionary tool in this accessible guide to ChatGPT's inner workings. Connecting Aristotle's philosophy to neural networks, Wolfram reveals why these systems work despite not being fully understood - a phenomenon he calls "Neural Net Lore" that's reshaping our understanding of intelligence.

The Probabilistic Poetry of Language Generation
At its heart, ChatGPT operates with elegant simplicity - predicting one word at a time. Imagine a system constantly asking itself: "Given everything written so far, what word most likely comes next?" Rather than following rigid grammatical rules, it builds a statistical model from billions of human-written texts, learning patterns that make language feel natural. When generating text, ChatGPT doesn't mechanically follow a script but makes probabilistic choices at each step. The system ranks possible next words based on their likelihood in context, sometimes choosing the most probable option, sometimes selecting from several plausible continuations. This process mirrors how humans write - balancing convention with creativity, familiar phrases with unexpected turns. What makes this particularly fascinating is the "temperature" setting that adjusts randomness. Set low, ChatGPT becomes predictable, consistently choosing the most likely words. Increase the temperature, and it becomes more creative, willing to select less obvious continuations that might lead to more interesting text. By breaking language generation into probabilistic choices, ChatGPT reveals something fundamental about communication itself - perhaps the seemingly infinite complexity of human expression emerges from learnable patterns. What appears magical is actually a sophisticated statistical model making educated guesses, one word at a time.
