Pika H3 Flex
A Pika video model built on the open MiniMax H3 weights: it makes video with stereo sound at once in six steps and takes up to 12 reference materials (images, video, audio) that set the shot direction. Two adapters: FL2VA for text and the first and last frames, Ref2VA for reference materials. Locally it runs at 480p and 768p, while 1080p, 2K and 4K, audio stems and prompt enhancement are available only through the paid Pika API. It suits multi-shot stories, motion graphics and product films. The license inherits the MiniMax H3 terms and does not apply in the EU, the UK, South Korea and the USA, which has to be checked before use. Running it needs server-grade graphics cards.
