AISummary
Runway announced Gen-4.5, a video generation model that it says holds the top position on the Artificial Analysis Text-to-Video benchmark with 1,247 Elo points. The model is available across all paid Runway plans at comparable pricing, and the post lists limitations including causal reasoning errors, object permanence failures, and success bias.
AIWhy it matters
The post separates Runway's own ranking claim from the listed limitations, such as causal reasoning and object permanence errors, which helps judge where the model is reliable.
