Pika H3 Flex: open-weights video model with synced audio in 6 steps
Pika's post-trained MiniMax H3 generates 5-15 second clips with synchronised stereo audio in 6 sampling steps instead of 50, with up to 12 reference files per shot.
Why it matters
Open-weights video that renders faster than real time, with dialogue, score and effects as separate audio stems.
What you could build with it
A creator could generate short clips with synced dialogue and sound effects from a storyboard frame, iterating on a scene in six sampling steps instead of waiting on a 50-step render.
Does it hold up?
Usable now: in the Pika app since Nov 2 and via API, with weights and inference code open. The MiniMax H3 Community License excludes the US, EU, UK and Korea, so check the licence before any commercial use.
