Major US news outlets sued OpenAI in early February 2025, alleging that the company's AI chatbot, ChatGPT, had created training models using copyrighted online content. A widely shared social media post implies both a truth and a lie, despite the company's denial of the allegations and insistence that it only used "publicly-available content."

A video that was shared on Instagram showed several screenshots of ChatGPT straining to produce an image of a full wine glass. Despite the user's repeated requests to fill in the blank space, the AI was only able to produce images of half-filled wine glasses in each case.

The page argued that AI image generators like ChatGPT, which uses DALL-E models, find it difficult to produce a picture of a wine glass filled to the brim because they simply do not exist in plenty on the Internet.

Most photographic and film shots depict half-filled wine glasses as per our serving practices, usually seen at hotels or elsewhere.
