Pika drops H3 Flex: video and audio in just six steps
Pika just open-sourced Pika H3 Flex, a post-trained model built on MiniMax-H3 that generates videos with synchronized stereo audio in only six sampling steps. It handles 5-to-15-second clips across 11 aspect ratios, accepts up to 12 multimodal references, and runs on a single H100 GPU. Why it matters: professional creators get rapid, high-control iteration without waiting minutes for a render.
