# ChatGPT-5

**Type:** product (specific LLM iteration) · **Maker:** OpenAI.

A specific iteration of [[entity-chatgpt-d12]] tested by the author to identify the best men's tennis shoes. The bot provided a jarringly human-sounding explanation of its curation methodology — citing **expert reviews, retailer best-seller lists, and community feedback** — captured verbatim in [[quote-chatgpt5-methodology]].

This experiment is the source's most concrete evidence for [[claim-llms-prioritize-reddit-youtube]]: the model itself named community/retailer/expert sources when asked how it curated its answer, illustrating [[concept-single-answer-insights]] in action.
