Seek .(US:SKLTY) 3 6 Ke·2025-12-23 10:46Core Insights - The launch of TurboDiffusion by Tsinghua University and Shengshu Technology marks a significant advancement in AI video generation, reducing generation time from minutes to seconds while maintaining high quality [1][3][7]. Group 1: TurboDiffusion Overview - TurboDiffusion is an open-source video generation acceleration framework designed specifically for diffusion models, achieving speed improvements of 100-200 times on consumer-grade GPUs like the RTX 5090 [8][24]. - The framework allows for efficient video generation from both image-to-video (I2V) and text-to-video (T2V) inputs, maintaining impressive performance even for high-resolution and long-duration videos [8][14]. Group 2: Performance Metrics - In practical tests, TurboDiffusion demonstrated a speed increase of approximately 97 times, generating a 5-second video in just 1.9 seconds compared to the standard implementation which took 184 seconds [10]. - For a 14B model generating a 5-second 720P video, TurboDiffusion reduced the generation time from over 4549 seconds to just 38 seconds, achieving a speedup of about 120 times [14][17]. Group 3: Core Technologies - TurboDiffusion employs four key technologies: 1. SageAttention for low-bit quantization of attention mechanisms, enhancing GPU performance [24]. 2. Sparse-Linear Attention (SLA) to reduce redundant calculations in sparse computing, further accelerating inference [24]. 3. rCM step distillation to minimize the number of diffusion steps required without sacrificing quality [24]. 4. W8A8 INT8 quantization for linear layers, optimizing speed and reducing memory usage [24][26]. Group 4: Industry Impact - The introduction of TurboDiffusion is seen as a pivotal moment in the AI video generation industry, transitioning from a niche, time-consuming process to a more accessible and rapid content creation tool [29]. - The technology has already been integrated into various leading tech companies' products, showcasing its potential for significant economic benefits [26].
