OpenAI Sora vs Runway Gen 3 Alpha
Verdict: Runway Gen-3 Alpha wins for most users due to public availability and API access while Sora leads only in closed-demo quality metrics. Gen-3 Alpha supports 1080p at 24 fps with paid tiers (per Runway site) versus Sora's unreleased status. Sora trails on longevity because no release timeline exists after the 2024-02 announcement.
