Which one should you pick?

  • Trying the new generation for free or producing everyday short videos → Video 2.5 Flash: free for a limited time with all three generation modes.
  • Best quality (up to 2K), reference videos or image/audio references → the paid Video 2.5.
  • Longer durations (up to 20s), arbitrary pixel resolutions or negative prompts → the free Video 2.0 remains a solid choice.

The app still defaults to Video 2.0 so existing pipelines behave consistently; switch anytime in the settings panel or the Simple Video form.
