In a blog post on Monday, Runway says its Gen-4.5 model can produce "cinematic and highly realistic outputs," potentially making it even more difficult to distinguish between what's real and what's AI. "Gen-4.5 achieves unprecedented physical accuracy and visual precision," Runway's announcement says. It adds that the new AI model is better at adhering to prompts, allowing it to produce detailed scenes without compromising video quality. Runway says that AI-generated objects "move with realistic weight, momentum and force," while liquids "flow with proper dynamics."
Some specific improvements of the model include support for up to 10 reference images, meaning you can incorporate a lot more elements from different pictures in your final product; improved photorealism and detail; more accurate text rendering, a task image generating models frequently struggle with; better prompt following; and a better understanding of real-world knowledge, according to Black Forest Labs.
