Core Insights - The article discusses the rapid advancements in video generation models, particularly the performance of the Transformer-based DiT model, which is approaching real-life shooting effects. However, it highlights a significant bottleneck: long inference times, high computational costs, and challenges in increasing generation speed [2][29]. - A new approach called LeMiCa (Lexicographic Minimax Path Caching) is introduced, which is a cache acceleration framework that does not require training and achieves global optimal modeling while maintaining image quality and consistency [2][29]. LeMiCa Framework - LeMiCa addresses the long-standing issue of whether a truly "globally consistent, error-controllable, and fast" caching acceleration path exists for diffusion models, concluding that such a path does exist and is simpler than previously thought [2][7]. - The core idea of LeMiCa is that caching acceleration is not a local decision problem but a global path optimization problem [7]. Technical Implementation - The generation process of diffusion models can be abstracted as a weighted directed acyclic graph (DAG), where each node represents a time step and edges represent the behavior of skipping computations and reusing caches [8]. - LeMiCa introduces a novel error measurement method to quantify the impact of caching on the final video results by constructing a static DAG offline [11][12]. Optimization Strategy - The optimization problem is formalized as finding the optimal path from the start to the end within a fixed budget, using a lexicographic minimax path approach to ensure that the maximum error is minimized and the error distribution is more balanced [12][13]. - Experimental results show that LeMiCa achieves significant improvements in both speed and visual quality compared to other mainstream methods [14][19]. Performance Metrics - LeMiCa demonstrates a speedup of over 2.4× in inference performance while significantly enhancing visual consistency and quality across various video generation models [19][20]. - The framework has been validated across multiple mainstream video generation models, showing superior performance in maintaining visual consistency before and after acceleration [14][19]. Robustness and Compatibility - LeMiCa exhibits robustness in acceleration paths, maintaining effectiveness even when sampling schedules are altered [20]. - The framework is compatible with text-to-image models, as demonstrated with the QWen-Image model, achieving similar acceleration effects [21]. Industry Recognition - LeMiCa has received endorsements from top-tier multi-modal model development teams, including Alibaba's Tongyi Qianwen and Zhizhu AI, highlighting its significance in the industry [24][25]. Conclusion - LeMiCa redefines the acceleration problem in diffusion video generation from a global optimization perspective, breaking through the limitations of traditional local greedy caching strategies and providing a new paradigm for video generation that is both fast and stable [29].

Core Viewpoint - The report from Zhongyuan Securities indicates that a series of AI industry catalytic events will occur in 2026, strengthening the leading position of top optical module manufacturers due to their technological, customer, and scale advantages. The current valuation of the communication industry index is below the ten-year average, and the industry maintains a "stronger than the market" investment rating based on performance growth expectations and valuation levels [1][2]. Summary by Sections Review of 2025 - In early 2025, the DeepSeek large model boosted market sentiment, and the three major operators completed the deployment of DeepSeek computing power private networks, enhancing their cloud service capabilities. Domestic cloud manufacturers provided positive capital expenditure guidance, leading to an increase in industry valuations. However, from February to April, the industry index experienced significant fluctuations due to concerns over U.S. tariff policies and future demand for optical modules. By mid-April, the easing of tariff policies and validation of AI computing power demand led to a gradual recovery in the industry index and valuations. In late July, North American cloud manufacturers raised their capital expenditure guidance, further catalyzing the industry. Since September, leading manufacturers faced short-term performance fatigue due to product iterations and customer structure adjustments, raising concerns about unclear downstream business models [2]. Outlook for 2026 - A series of AI industry catalytic events are expected, including the mass production of NVIDIA's next-generation Rubin GPU, the release of Google's new large model Gemini, and clear capital expenditure guidance from cloud manufacturers. AI smartphones equipped with large models are anticipated to become personalized smart assistants, potentially driving the next wave of smartphone upgrades. The development of key 6G technologies by telecom operators is expected to accelerate revenue growth from AI computing power. The report is optimistic about the high industry prosperity and strong growth potential of optical modules, optical devices, optical chips, and the increasing penetration of AI smartphones, as well as the stable operations of quality dividend assets in telecom operators [3][4]. Capital Expenditure Outlook for Leading Cloud Manufacturers - The demand for 800G is increasing, and the industry is transitioning from 800G to 1.6T technology. Leading optical module manufacturers are expected to further highlight their advantages due to technological leadership, stable customer relationships, and scalable delivery capabilities. The development of AI is driving the construction of large data centers, benefiting optical device manufacturers. The long R&D and expansion cycles for optical chips create high barriers in technology, talent, customer validation, and capital, leading to a persistent supply-demand gap for certain optical chips. The increasing demand for domestic controllable solutions is expected to translate into performance for domestic computing power. Recommended companies to watch include: NewEase, Huagong Technology, Guangxun Technology, Yuanjie Technology, Shijia Photon, and Taicheng Light [4]. AI Smartphones and Market Trends - Generative AI smartphones are set to provide users with new interactive experiences, multimodal content generation capabilities, personalized services, and innovative application ecosystems. The continuous improvement of edge AI computing power and large model capabilities is expected to further increase the market penetration of AI smartphones. Innovations and upgrades in AI smartphones are likely to lead to higher average selling prices and improved profit margins. The growth in edge AI shipments will drive sustained growth in core product lines of consumer electronics components [5]. Telecom Operators' Performance - The three major telecom operators are considered quality dividend assets with high dividend yield potential, offering cash dividends twice a year. The quality of traditional business revenue is improving, and a decrease in capital expenditure is expected to lower future depreciation and amortization costs, maintaining stable operations. Additionally, telecom operators are likely to leverage their advantages in data centers, big data, and network infrastructure to reconstruct business models with the help of AI. Investment recommendations include focusing on the optical module, optical device, and optical chip sectors, as well as AI smartphone and telecom operator sectors [6].
