Recently, OpenAI unveiled a demo of its new Sora video AI model, to which Runway CEO Cristóbal Valenzuela responded with just two words: "game on," signaling the start of fierce competition in the video AI sector. Companies like Runway, Google, and Stability AI have since rolled out new models in response to OpenAI's Sora, intensifying the competition in video AI. Runway has recently launched an update to Gen-2, valued at $1.5 billion, while the capabilities and limitations of Sora remain unclear, further heating up the competitive landscape. The CEO of Stability AI's response to OpenAI indicates that the competition in the video AI field is becoming increasingly intense, with AI models continuously being updated as companies vie for a leading position.
