OpenAI

OpenAI is an American artificial intelligence research organization headquartered in San Francisco, structured as both a for-profit public benefit corporation and a nonprofit foundation. The lab developed the GPT family of large language models, the DALL-E image generation series, and the Sora video models. Its launch of ChatGPT in November 2022 is widely credited with catalyzing mainstream interest in generative AI.

OpenAI's catalog spans 17 models across text, image, and video generation. Flagship text models include the GPT-5.4 family — GPT-5.4, GPT-5.4 Pro, and the lightweight GPT-5.4 Mini — alongside specialized coding variants like GPT-5.2 Codex and GPT-5.3 Codex. Open-weight offerings include GPT OSS 120B and GPT OSS 20B. Image generation is covered by GPT Image 1.5, while Sora 2 and Sora 2 Pro handle both text-to-video and image-to-video tasks.

OpenAI occupies a unique position as both a leading proprietary AI provider and, increasingly, an open-weight contributor with its GPT OSS releases. The breadth of its catalog — spanning language, image, and video modalities — reflects one of the widest capability ranges of any single AI lab.
