Zhong Guo Jing Ying Bao·2025-10-21 14:35Core Insights - The competition in the video generation model sector has intensified significantly following the launch of OpenAI's Sora2, which features 10-second audio-visual integration and social sharing capabilities, leading to a viral response and increased pressure on domestic video model teams [2][3]. Group 1: Industry Response - Domestic video generation model teams, including Baidu's Steam Engine and Kuaishou AI, have ramped up their efforts, with teams working continuously during the National Day and Mid-Autumn Festival holidays to keep pace with Sora2's impact [2][3]. - Baidu's Steam Engine team has demonstrated rapid innovation, achieving two major updates within 50 days, showcasing the urgency and intensity of competition in the sector [3]. Group 2: Technological Advancements - The latest upgrade of Baidu's Steam Engine has broken the traditional 10-second video generation limit, enabling real-time interactive long video generation, allowing users to modify content during the creation process, marking a shift from "one-time output" to "dynamic creation flow" [4][6]. - The team has innovatively combined autoregressive streaming generation with diffusion models to address the challenges of real-time video generation, which typically faces exponential cost increases with longer time windows [5][6]. Group 3: Market Dynamics - The competitive landscape is characterized by a lack of long-term technological advantages, with execution speed becoming the key differentiator among teams [4][5]. - Despite Sora2's popularity, Baidu's Steam Engine team plans to maintain its pricing strategy, focusing on long-term cost reductions through technological advancements rather than engaging in short-term price wars [6].
