How to Pick Between Seedance 2.0, Kling 3.0, and Sora 2 for Your Video API Integration

If you're building anything that touches AI-generated video right now, you've probably noticed the field got crowded fast. Three models — Seedance 2.0, Kling 3.0, and Sora 2 — keep coming up in every conversation. But the demo reels don't tell you what actually matters when you're wiring one of these into a production pipeline: availability, pricing, and how painful the integration will be. I spent time digging into the official docs and verified pricing for all three as of March 2026. Here's what I found.
