Runway Gen-4.5 vs Sora 2 Pro
Sora 2 Pro edges out Gen-4.5 overall (Gen-4.5 40.0 vs Sora 2 Pro 50.0.) Sora 2 Pro is pretty good at storytelling. When generating multi-scene outputs, it can maintain narrative consistency, offering a glimpse of what coherent one-shot narratives could look like. It excels at 2D and 3D animation. However, it performs worse than other frontier models like the Veo 3 set, with very poor logical consistency and extremely wide variance in output quality. Outside of the Sora App, for any serious use case the recommendation is still Kling, Seedance, or Veo. The main tradeoffs are in Logical consistency, Wide quality variance, Expensive, where Gen-4.5 tends to score better.

Physics
How well the model simulates real-world physics: gravity, momentum, collisions, and natural movement.
Sora 2 Pro leads on physics (+1.9), with a measurable advantage over Gen-4.5. The clearest separation is on Physics (+1.9). Across the other sub-metrics in this group, the gap is smaller but generally consistent with the overall direction. If physics is a priority for your prompts, Sora 2 Pro is the safer pick here.

Prompt
Inside a gilded palace ballroom with tall mirrors and a marble floor, a gold crown sits on a red velvet cushion on a small round table in the foreground. A silver candlestick stands exactly to the right of the cushion. In the background, a crystal chandelier hangs centered above the room. At second 2 the chandelier sways gently left-to-right for exactly three seconds; at second 6 a gloved hand enters from the left and extinguishes only the rightmost candle on the candlestick. The crown and cushion must never move.”

Prompt Adherence
Prompt
Single continuous shot in a sci-fi hangar with glossy floors and strong backlight haze. Keep a parked spaceship on the left, a glowing door panel on the right wall, and a metal crate centered in the foreground. A female lead runs from the background toward the crate and pivots around it without touching it. A small drone swoops in from the right and scans her with a sweeping light beam as it passes overhead. She slides behind the crate for cover, then pops out and slaps the glowing door panel once. The door panel flashes brighter and she holds in a ready stance facing it. The crate must never move and the spaceship must remain stationary. No cuts.

Single continuous macro shot inside a watchmaker’s workshop. Extreme close-up of tweezers placing a tiny brass gear into a mechanical watch movement. The engraved markings on the gear remain crisp and identical frame-to-frame. The tweezers and gear never warp or change shape, and the camera motion is a smooth, slow push-in with no jitter. The gear teeth must not shimmer or crawl as it settles into place.
