Best AI Video Generation Models in 2026: Complete Guide with FAL.AI
2026 is the year AI video generation went mainstream. Models like Kling 2.6, Veo 3.1, and Sora 2 can now create cinematic videos with native audio, lip-sync, and sound effects—directly from text prompts.
This guide covers the best video generation models available through FAL.AI. Whether you need talking avatars, product animations, or full cinematic scenes, we'll help you choose the right model for your use case.
🔊 The Audio Revolution
The biggest breakthrough in 2026: native audio generation. Models no longer just create silent video—they generate synchronized dialogue, sound effects, ambient noise, and even music.
💰 Cost tip: Audio is optional on most models and typically doubles the price. For Kling 2.6: $0.07/sec without audio → $0.14/sec with audio. Generate silent videos first, then add audio only when needed.
🎬 Real Video Samples: Model Comparison
