Miscellaneous
OpenAI
Founded in 2015 as a nonprofit and later reorganized as a capped-profit company, OpenAI has produced some of the most influential AI systems: GPT series, ChatGPT, DALL-E (image generation), Codex (code generation), and Whisper (speech recognition). Its research on scaling laws and RLHF has shaped the field.
OpenAI's API provides programmatic access to GPT-4 and other models, powering thousands of applications. ChatGPT's launch in 2022 accelerated mainstream AI adoption and intensified competition from Google, Anthropic, and Meta.
