Sume compared with other video and generative-media platforms. Each post uses the vendor's own pages, read on the date the post states.
STT language: Sume language_code hint vs the 60 languages MAI lists
Sume STT takes an optional language_code and auto-detects when omitted. A tracker lists MAI-Transcribe-2-Streaming at 60 languages; Sume's docs state no count.
Talking presenter: Fabric still plus voice, or video model plus voice?
Sume docs: video models do not lip-sync to TTS, so use a still plus audio on Fabric ($0.1875/s at 720p listed). Wan 3.0 is cheaper but will not match the voice.
A/B test two video models: pin the ids, sume/auto hides the family
sume/auto always reports model sume/auto and never discloses the family that ran, so it cannot A/B two models. Pin both ids; a 5 s 480p pair costs $0.76.
Six stills and a logo clip as references: Wan 3.0, Omni, H3 or Kling?
For a brand-kit video with six stills and one logo clip, Wan 3.0 and MiniMax H3 fit; Omni caps clips at 3 s; Kling 3 takes no references. 8 s prices inside.
MAI-Voice-2.1 or Sume TTS for a presenter ad read: 3 prices
