Runway announced its new Gen-4.5 text-to-video AI model, claiming it delivers unprecedented physical accuracy and visual precision. The model reportedly handles complex prompts better, rendering realistic object motion, fluid dynamics, and a range of visual styles without sacrificing video quality. While rolling out gradually to all users, Runway acknowledges limitations in object permanence and causal reasoning. The release coincides with OpenAI’s own advances, including its Sora 2 model, which also emphasizes realistic physics. Both companies aim to make AI‑generated video increasingly lifelike and difficult to distinguish from real footage. Leer más →
