Runway just dropped Gen 4.5 and it's making some serious noise in the AI video space. This isn't just another incremental update - they're claiming it beats Google's Veo 3.1 on key benchmarks for realism and motion quality.
What sets Gen 4.5 apart is the focus on three core improvements:
Motion Quality - Characters and objects move with more natural physics instead of that weird AI floaty feeling
Visual Coherence - Details stay consistent across frames rather than morphing or flickering
Temporal Stability - The video maintains its structure throughout instead of devolving into chaos
Side-by-side comparisons with Veo 3.1 are showing sharper, more cinematic results. The physics engine seems to understand how things actually move in the real world - which is huge for anyone trying to create professional-looking content.

This feels like the video generation race is heating up fast. Google just launched Veo, and now Runway's already claiming the crown back.
