Interview with OpenAI Chief Scientist Jakub Pachocki: AI May Autonomously Discover New Science Within 5 Years, World Models and Reinforcement Learning Are Key: OpenAI Chief Scientist Jakub Pachocki stated in an interview with Nature magazine that AI is expected to achieve autonomous scientific discovery within 5 years and have a significant impact on the economy. He believes that current reasoning models (such as o-series, Gemini 2.5 Pro, DeepSeek-R1) solve complex problems through methods like chain-of-thought and have already shown great potential. Pachocki emphasized the importance of reinforcement learning, which enables models not only to extract knowledge but also to form their own ways of thinking. He predicts that AI may not yet be able to solve major scientific problems this year, but it can almost autonomously write valuable software. Regarding AGI, Pachocki believes its important milestone is the ability to generate quantifiable economic impact, especially by creating entirely new scientific research. He also mentioned OpenAI’s plans to release open-source model weights better than existing models to promote scientific progress, but safety issues also need attention. (Source: 36Kr)

Ant Technology Research Institute’s Wu Wei Discusses Next-Generation Reasoning Model Paradigm: Wu Wei, Head of Natural Language Processing at Ant Technology Research Institute, believes that current reasoning models based on long chains of thought (such as R1), while demonstrating the feasibility of deep thinking, may not be stable enough due to their high dimensionality and high energy consumption. He speculates that future reasoning models might be lower-dimensional, more stable artificial intelligence systems, analogous to the principle in physics and chemistry where the lowest energy structure is the most stable. Wu Wei emphasized that in human daily thinking, System 1 (fast thinking), which consumes less energy, often predominates. He also pointed out the problem of current models producing correct results but potentially through incorrect processes, and the challenge of high error correction costs in long chains of thought. He believes that the thinking process itself may be more important than the result, especially in discovering new knowledge (such as new mathematical proofs), where deep thinking has enormous potential. Future research directions should explore how to efficiently combine System 1 and System 2, possibly requiring an elegant mathematical model to characterize AI’s way of thinking, or achieving system self-consistency.

ICLR 2025 Paper OmniKV: Proposes Efficient Long-Text Inference Method Without Discarding Tokens: Addressing the significant KV Cache memory overhead in long-context Large Language Model (LLM) inference, researchers from Ant Group and other institutions published a paper at ICLR 2025 proposing the OmniKV method. This method leverages the “inter-layer attention similarity” insight, where different Transformer layers exhibit high similarity in their attention focus on important tokens. OmniKV calculates full attention only in a few “Filter layers” to identify important token subsets. Other layers then reuse these indices for sparse attention computation and offload the KV Cache of non-Filter layers to the CPU. Experiments show that OmniKV, without discarding tokens and thus avoiding critical information loss, achieves a 1.7x throughput improvement over vLLM on LightLLM, and is particularly suitable for complex reasoning scenarios like CoT and multi-turn dialogues.

AI Learning Tip: Avoid Introducing Dynamic Content in Multi-Turn Dialogues to Protect KVCache: When engaging in multi-turn dialogues with AI, especially when computing power is limited, try to avoid introducing dynamic content into the context, such as the current timestamp. Dynamic content causes the generated token sequence to differ each time, forcing the model to recompute the KVCache for the entire sequence, thus preventing effective cache reuse and increasing computational overhead. Complex UI operations, like naming a chat session mid-conversation, can also invalidate the KVCache. One way to determine if the KVCache is invalidated is to observe memory fluctuations during inference; frequent large swings usually mean the KVCache is not being effectively reused.

Systematically Learning “Problem-Solving Ability” with AI: User “周知” (Zhou Zhi) shared their process of deeply understanding “problem-solving ability” through progressively advanced AI usage methods. Starting from using AI as a search engine for superficial information, to assigning AI expert roles like Feynman for structured questioning, and then utilizing well-designed built-in prompts (like Li Jigang’s Cool Teacher prompt) to have AI provide systematic, multi-dimensional knowledge explanations (definition, schools of thought, formulas, history, connotation, extension, system diagrams, value, resources). Finally, by having AI extract, organize, and understand this information, and combining it with practical application scenarios (like learning to write AI prompts), abstract concepts were transformed into actionable frameworks and guidelines.

Gap Exists Between AI’s High Scores in Medical Q&A and Real-World Application Effectiveness: A study by Oxford University had 1298 ordinary people simulate medical consultations, using AI like GPT-4o and Llama 3 to assess the severity of their conditions and choose a course of action. The results showed that although AI models achieved high diagnostic accuracy when tested alone (e.g., GPT-4o identified diseases with 94.7% accuracy), the proportion of users correctly identifying diseases actually decreased to 34.5% when using AI assistance, lower than the control group that did not use AI. The study pointed out that incomplete user descriptions and inadequate understanding and adoption of AI suggestions were the main reasons. This indicates that AI’s high scores in standardized tests do not fully equate to effectiveness in real clinical applications, with the “human-AI collaboration” link being a key bottleneck.

Advertising agencies like WPP and Publicis are also embracing AI, training teams or developing tools. However, AI ad production still faces challenges: technically, issues like unstable visuals, easily distorted human faces, and poor handling of complex dynamics require manual intervention; public opinion-wise, over-hyping technology or lacking creative sincerity can easily cause backlash; legally and ethically, there are no uniform standards for material copyright, privacy protection, AI-generated content authorship, and infringement liability. Successful cases often focus on conveying “humanity” and care, leveraging technology’s strengths while mitigating weaknesses, and aligning with brand identity. (Source: 36Kr)
100 Scientists Co-sign “Singapore Consensus,” Proposing Global AI Safety Research Guidelines: During the International Conference on Learning Representations (ICLR) in Singapore, over 100 scientists from around the world (including Yoshua Bengio, Stuart Russell, and others) jointly released the “Singapore Consensus on Global AI Safety Research Priorities.” The document aims to provide guidance for AI researchers to ensure AI technology is “trustworthy, reliable, and safe.” The consensus proposes three research categories: identifying risks (e.g., developing metrics to measure potential harm, conducting quantitative risk assessments), building AI systems in ways that avoid risks (e.g., making AI reliable by design, specifying program intent and undesirable side effects, reducing hallucinations, improving robustness to tampering), and maintaining control over AI systems (e.g., extending existing safety measures, developing new techniques to control powerful AI systems that might actively subvert control attempts). This initiative aims to address the safety challenges posed by the rapid development of AI capabilities and calls for increased investment in safety research. (Source: 36Kr)
