これは何か

OpenAI was founded in 2015 as a non-profit research lab aiming to advance general-purpose AI safely. From 2018 it moved to a capped-profit structure with investment from Microsoft, turning research into APIs and consumer products. Its main line is the GPT family of autoregressive language models, which established pretraining plus human-feedback fine-tuning as the conversation-model recipe. ChatGPT launched in November 2022, bringing large language models into everyday use.

なぜ重要なのか

It turned pretraining plus human-feedback fine-tuning into the standard recipe for chat models, and its 2022 release of ChatGPT brought large models to a mass audience — after which the industry set its release cadence and pricing around OpenAI.
