2. Zhipu’s Hong Kong Stock Soars 42%. Zhipu’s stock price surged by a whopping 42.72% in late trading, settling at HK$725 and pushing its market cap past 323.2 billion. This happened on the first trading day of the Year of the Horse for Hong Kong stocks, where the AI sector was on fire. Meanwhile, MINIMAX also jumped 12% to HK$957 on the same day. Both major large model companies have now surpassed 300 billion (AI News) in market value.

Cutting-Edge Research

1. MedOS: The First Medical World Model. MedOS, the world’s first general-purpose medical embodied world model, has been unveiled by Stanford and Princeton. This game-changing model can perceive, simulate, and intervene in the physical world, covering everything from diagnosis to surgery. Interestingly, when assisted by MedOS, junior doctors’ accuracy now rivals that of seasoned experts! The paper is published (AI News) .
   
   

2. Inference Evolution: From AlphaGo to R1. Eric Jang penned an article reviewing the evolution of inference technology, tracing its path from AlphaGo’s search-and-intuition approach to the RL emergence seen in DeepSeek-R1. He highlights the spontaneous formation of inference circuits under outcome supervision as a crucial breakthrough. Jang predicts that future inference might even happen between forward propagation layers, and humorously forecasts “007” becoming the new “996” (AI News) .

3. VisPhyWorld: Verifying Physical Reasoning with Code. Researchers have introduced the VisPhyWorld framework, which challenges models to generate executable simulation code directly from video observations. Across 209 scenarios, it achieved an impressive verification rate of 97.7%. The findings indicate that while MLLMs boast strong semantic understanding, they still struggle with physical parameter inference. The paper link (AI News) is definitely worth checking out.

4. S2Q: A New Algorithm for Multi-Agent Collaboration. The multi-agent reinforcement learning (MARL) field just got a cool new method: S2Q. This algorithm learns multiple sub-value functions while retaining alternative actions, maintaining continuous exploration capability through a Softmax strategy. Experiments consistently show it outperforming existing algorithms on MARL benchmarks, and the code is open-sourced on GitHub (AI News) .

5. MolmoSpaces: A Large-Scale Testing Platform for Robots. This project, MolmoSpaces, has built over 230,000 indoor environments, packed with 130,000 labeled object assets and 42 million stable grasps. It supports mainstream simulators like MuJoCo, achieving a stunning correlation of R=0.96 with real-world scenarios. The paper details (AI News) reveal its incredible sim-to-real transfer effectiveness. 🔥

6. PROBE: Measuring AI’s Proactive Problem-Solving Ability. PROBE, a new benchmark, zeroes in on evaluating AI’s proactivity, breaking it down into three steps: searching for problems, identifying bottlenecks, and executing solutions. The best end-to-end performance only hit 40%, with GPT-5 and Claude Opus-4.1 tying for the top spot. This full paper (AI News) definitely sheds light on the current limitations of AI agents.💡

Industry Outlook & Social Impact

1. Nvidia and OpenAI Deal Shrinks by 70%. The Nvidia and OpenAI deal for a whopping $100B investment has reportedly plummeted to just $30B. The community is already likening a possible OpenAI IPO to “WeWork 2.0,” raising doubts about the moat around LLM technology as it moves towards commodification. Its hardware reliance on Nvidia is seen as a core risk, and this source report (AI News) has sparked a huge debate about a potential valuation bubble. 💥

2. Ggml.ai Joins Hugging Face. Ggml.ai has officially teamed up with Hugging Face, with the goal of ensuring the long-term development of local AI. The community often sees HF as an “unsung hero” of the open-source ecosystem, but the sustainability of its business model still sparks some debate. While local inference technology is totally feasible, it does require hardware trade-offs (AI News) . 🤗

3. Is AI Making You Boring? An HN hot topic has ignited a 343-point discussion, exploring whether AI is making us, well, boring. “Vibe-coding” seems to be flooding Show HN with quick-and-dirty projects, and LLM-generated emails and documents are leading to a surge in “attention debt.” Critics worry about long-term skill degradation and a loss of originality, while supporters argue that AI is just an amplifier, with the key really being the user’s taste (AI News) . 🤔

5. AI’s Biggest Perk: Quickly Witnessing Mediocrity. Jike user Yubo posted a poignant reflection, lamenting that even with AI writing articles, nobody’s reading them. And short videos? He admits he doesn’t even want to watch his own! What’s more, attempts to make money often result in losses. He concludes that ultimately, those who can truly leverage AI are surprisingly the ones who weren’t tech-savvy to begin with. His original post sparked (AI News) countless echoes. 😅

6. Tech Folks Need to Break Free from Cognitive Cages. Jike user Beiguo Sangma directly stated that pure tech individuals often end up working their entire lives for those who understand business. They get caught in the arrogant “tech is everything” mindset and can’t seem to break free. Tech, capital, and traffic are merely business elements. He points to Zhang Yiming as a prime example of someone who broke through this cognition (AI News) . 💬

7. AI Development Should Be Divided into Four Waves. Fang Zhou (talking about AI) proposed a fresh perspective, suggesting that AI development should be categorized into four waves. The first three were Symbolism, Machine Learning, and Deep Learning. He argues that large models have kicked off the fourth wave, bringing about a qualitative leap: moving from perceptual discrimination to cognitive generation. We’re currently right at the junction (AI News) of this fourth AI wave and the Industrial Revolution. ✨
