how does, say, chatGPT write essays?
The answer lies in probabilistic token prediction, not plagiarism or reasoning.
Deep Dive
A Reddit user wonders: when ChatGPT writes an essay, does it just copy-paste from other articles, or does it actually think—analyzing information, forming opinions, deciding structure, making connections, and self-editing? The user clarifies they're not cheating on homework, just fascinated by how the technology works.
Key Points
- ChatGPT uses a transformer with 175 billion parameters (GPT-3.5/GPT-4)
- It generates each token probabilistically, not by copy-pasting sources
- Training data includes millions of essays, enabling plausible structure without real reasoning
