Does ChatGPT’s one-line style come from chat data or product tuning?

The post asks whether ChatGPT’s habit of breaking explanations into short one-liners may come from training on chat transcripts, including private conversations, or whether OpenAI intentionally tuned the response format.

The author notes that ChatGPT often answers with a summary, then a divider/title, then a series of short lines instead of a single coherent paragraph. They wonder whether this mirrors how people text friends, or whether it is a deliberate product choice to make responses feel more readable.

The thread is essentially a question about whether the model learned the style from data or from alignment and formatting decisions, and why OpenAI would prefer that style if it feels unnatural in text.
