Pika launches H3 Flex, a fast video model it calls the top open-weight text-to-video model on DesignArena

Pika introduced H3 Flex, which it says debuts as the #1 open-weight model on DesignArena's text-to-video board (Pika's claim). It describes the model as built for professional iteration: exportable audio stems, resolutions up to 4K and faster-than-realtime generation, with a 15-second clip and soundtrack in as little as 7 seconds.

An account that shared the post gives more figures that Pika's own post does not: post-trained on MiniMax H3, about $0.02 per second, up to 12 image, video or audio references, and #7 on DesignArena's board. Treat those as unconfirmed.
