AI Video Generation Comparisons 2026

AI video tools all turn prompts into clips, but they differ sharply on how you pay and what they are for. Runway, Pika and Kling keep free or trial credits; Luma has no free door; Veo is metered per second through an API or bundled into Google AI plans. The axes that matter are the metering model (credits vs per-second vs subscription), output length and resolution, native audio, and whether you edit inside the same tool. This page collects every head-to-head across the five so you can jump to the matchup you want. Prices come from each vendor's live pricing page and were re-checked on the date shown.
