Pika released H3 Flex, a post-trained H3 video model that generates faster than real time in nearly every configuration — a 15-second clip in as little as 7 seconds, on average 1.8x faster and 80% cheaper than H3Max. Built for professional iteration: up to 4K resolution, up to 12 reference inputs, draft-at-768p/finish-at-4K workflow, and exportable audio stems for isolating parts of the soundscape. Available via the Pika API.
