Sora 2 vs Runway Gen-4 AI video comparison

2026 is the year AI video stopped being a novelty. OpenAI's Sora 2, Runway Gen-4, and Pika 2.5 all produce clips good enough for ad campaigns, music videos, and short-form social content. We tested all three on the same prompts. Here's what we found.

Why AI video matters now

According to the IAB's 2026 video advertising report, 14% of social ad creative shipped this year had at least one AI-generated shot. Production timelines for short-form content compressed from weeks to hours.

The contenders

Sora 2

OpenAI doubled clip length to 60 seconds, added camera-control prompts, and introduced "scene continuity" — characters and locations stay consistent across cuts.

Runway Gen-4

The pro filmmaker's tool. Best motion-brush controls, native green-screen, and multi-shot timeline editing.

Pika 2.5

The best value option. Lower fidelity than Sora but extremely fast and cheap, ideal for social-first creators.
