Sora 2

OpenAI's video model, known for physics realism and synchronized dialogue, with clips up to 25 seconds on the Pro tier.

Pros
  • Longest single-pass clips of the pair, up to 25 seconds on Pro
  • Reviewers consistently praise its motion and physics realism
  • Dialogue and sound effects generate in the same pass
Cons
  • Base tier caps at 720p, true 1080p costs 3 to 5 times more
  • Per-second pricing climbs fast at daily posting volume

Veo 3.1

Google's video model, with native audio across all tiers, a 4K premium option, and the cheapest entry pricing of the leading models.

Pros
  • Entry pricing from $0.03 per second on the Lite tier
  • 4K premium tier reconstructs real detail rather than upscaling
  • Spatial audio that pans with on-screen motion
Cons
  • 8 seconds per generation, longer shots need chained calls
  • Consumer credit math is opaque across the Flow plans

Our Verdict

Pick Sora 2 when: You need the longest possible single take with dialogue, physics-heavy motion, or you already build on the OpenAI API.

Pick Veo 3.1 when: You want the cheapest entry point, native audio on every tier, 4K output, or you live inside the Google stack.

Both are clip generators, and the model is the easy part. An AI influencer channel needs a consistent character, daily hooks, and a publishing schedule, which is the part AvatarFactory handles in one pipeline.
