# OpenAI GPT

**Profile:** A widely used family of large-language models from OpenAI powering ChatGPT and enterprise API use. Canonical reference: the OpenAI product page for GPT-4 / GPT models.

**Role in source:** Named as a strong candidate for the **generation agent** layer in a structurally diverse AI tech stack (see [[concept-structural-ai-diversity]] and [[action-diversify-tech-stack]]). GPT (as ChatGPT) is also the exemplar in the WEIRD-bias research — see [[concept-weird-bias-in-ai]] and [[claim-weird-bias]] (Atari et al.).
