TMTPOST -- Step AI, one of six leading Chinese AI startups, in collaboration with Geely Auto Group, released two open-source Step series multimodal models on Tuesday. These models are now available for global developers.

The first model, Step-Video-T2V, is the world's largest and most powerful open-source video generation model, boasting 30 billion parameters. It can generate 204-frame, 540P resolution high-quality videos.

The second model, Step-Audio, is the industry's first product-level open-source speech interaction model, with 130 billion parameters. It can generate emotional, dialectic, and personalized speech styles, providing natural, high-quality conversations and high-fidelity voice recreations for various industries like entertainment, social media, and gaming.

Step AI released the Stepeval-Audio-360 benchmark, a multidimensional evaluation system, and a new video quality evaluation dataset, Step-Video-T2V-eval, to assess 11 aspects of video generation, including motion, aesthetics, and realism. The Step-Video-T2V model excelled in areas like instruction compliance and motion smoothness.

On the same day, Kunlun Wanwei, a leading Chinese Internet company, also released two open-source video generation models—SkyReels-V1 for AI short films and SkyReels-A1 for facial action control. SkyReels-V1 is the largest model for both text-to-video and image-to-video generation, offering enhanced efficiency and lower latency.
