SAN FRANCISCO (AP) — OpenAI has publicly released its new artificial intelligence video generator Sora but the company won't let most users depict people as it monitors for patterns of misuse. Users of a premium version of OpenAI's flagship product ChatGPT can now use Sora to instantly create AI-generated videos based on written commands. Among the highlighted examples are high-quality video clips of sumo-wrestling bears and a cat sipping coffee.
