Core Insights - The article discusses the challenges of using Reinforcement Learning (RL) to fine-tune diffusion models like Stable Diffusion, particularly the issue of "Reward Hacking" which can degrade image quality [2][5] - A new framework called GARDO (Gated and Adaptive Regularization with Diversity-aware Optimization) is introduced, which aims to prevent Reward Hacking while enhancing sample exploration and diversity generation [2][12] Background and Motivation - RL has shown promising results in visual tasks, but defining an ideal reward function is challenging, often leading to the use of proxy rewards that can result in Reward Hacking [5][4] - The article highlights the pitfalls of RL post-training, including low sample efficiency and hindered exploration due to static reference models [9][10] GARDO Framework - GARDO is designed to address the issues of Reward Hacking by implementing three core insights: 1. Gated KL Mechanism, which applies KL regularization only when the model generates samples in unreliable reward regions [14][15] 2. Adaptive Regularization Target, which updates the reference model to prevent optimization stagnation [17] 3. Diversity-Aware Advantage Shaping, which encourages diversity in generated samples to avoid mode collapse [18][19] Experimental Results - GARDO has been tested on various base models (SD3.5-Medium, Flux.1-dev) and demonstrated significant advantages over baseline methods like Flow-GRPO [20][21] - The framework effectively prevents Reward Hacking while maintaining high image quality and sample efficiency, achieving better performance with fewer training steps [22][23] Emergent Behavior - GARDO has shown the ability to generate a higher number of objects in challenging tasks, indicating its potential to unlock new capabilities in visual generation [24][25] Conclusion - The work emphasizes that precise control is more important than strict constraints in visual generation using RL, making GARDO a valuable framework for researchers and developers looking to leverage RL in diffusion models [27]

Kuaishou Conference Call Summary Company Overview - Kuaishou is positioned as an aggressive player in the market, actively investing in Japan, South Korea, and Southeast Asia. The O one and 2.6 models have shown progress in motion control features, indicating potential for sustainable long-term growth [2][4]. Financial Performance - Kuaishou's market capitalization is approximately 300 billion RMB (44 billion USD). Its AI video product "Possible" has reportedly surpassed competitor Minimax's "Conch" in revenue, with expected monthly revenue exceeding 20 million USD by December 2025, leading to an annual recurring revenue (ARR) of 240 million USD. If "Possible" achieves an annual revenue of 2.5 billion RMB in 2026, the company's valuation elasticity will further improve [2][5]. - The company is nearing breakeven in its core business, with adjusted net profits projected at 20.6 billion RMB and 23.7 billion RMB for 2025 and 2026, respectively. The valuation of Hong Kong internet companies is relatively low, and Kuaishou's main business remains robust, with growth potential for the "Possible" product [2][6]. Market Position and Competitive Landscape - Kuaishou has a clear overseas strategy, leveraging domestic labor cost advantages and synchronized technological development. It leads in algorithm and user experience compared to domestic competitors like Deyi and Aisike Technology, as well as international players like OpenAI and Google. The "Possible" 2.5 model ranks in the top three in both video and image generation fields [2][7]. - Despite Google View and OpenAI Solo having superior funding and technology, they primarily target large film companies with high pricing. Kuaishou's competitive edge lies in optimizing image generation quality while maintaining reasonable pricing, making it more market-competitive [2][8]. AI Video Generation Market Potential - The AI video market is projected to reach 100 to 200 billion USD. By 2025, global multimedia revenue is expected to be 220 billion USD, with an AI penetration rate of 10%, leading to an estimated AI video market size of about 25 billion USD. Kuaishou has significant potential in the To C content generation platform, with expectations for exponential growth in the long term [3][11][12]. - The market analysis indicates a total market space of approximately 22.1 billion USD, considering B-end enterprises, C-end creators, and professional institutions [11]. Advertising Business and AI Integration - AI has significantly empowered Kuaishou's advertising business, contributing approximately 4% to 5% of revenue in Q3 and Q4 of 2025. Given the current low valuation and the positive results reported by major internet companies since 2024, this trend is expected to continue as technological breakthroughs occur [3][13].
