Pika releases open-weight H3 Flex video model, citing DesignArena ranking
Overview
Pika releases H3 Flex, a video model it post-trained from MiniMax's H3, and says it is the #1 open-weight text-to-video model on DesignArena's leaderboard.
DesignArena reports that H3 Flex scores a 1293 Elo rating and ranks #7 on its Video leaderboard, just ahead of FLUX 3 Video, Minimax H3 Max, and Minimax H3, and is the highest-ranking open-weights video model on that board. Pika says H3 Flex also ranks #7 in overall quality on a leaderboard, ahead of the MiniMax H3 base model and H3Max.
Pika says the model supports exportable audio stems, resolutions up to 4K, and can generate a 15-second clip with soundtrack in as little as 7 seconds. Pika released the code on GitHub, the weights on Hugging Face, and support for ComfyUI and diffusers.
H3 Flex is available on the Pika API Club from $0.01 per second. Pika is giving away 15 generations per day for the next two weeks.
