    Pika brings H3 Flex to its creation platform

    Pika says H3 Flex is now available on its platform, with faster-than-realtime generation, exportable audio stems, and output up to 4K. Those capabilities and its claim that it leads DesignArena's open-weight text-to-video board come from Pika; the ranking hasn't been independently checked here.
