Claude Fable 5 Disproves 85-Year-Old Mathematical Conundrum “Jacobian Conjecture” : Scholars from Stanford and the University of Chicago, along with multiple sources, revealed that Anthropic’s Claude Fable 5 (as well as OpenAI’s internal offline Codex) successfully found a low-degree counterexample to the 3D Jacobian Conjecture. This conjecture has baffled generations of algebraic geometers since it was proposed in 1939, and even caused mathematician Yitang Zhang’s doctoral thesis to falter. This breakthrough demonstrates that frontier AI models have shown superhuman intuition and creativity when dealing with open mathematical problems and unstructured search spaces, pushing mathematical research toward its AlphaGo moment.

📚 Research
Tsinghua University Proposes SEED Framework, Enhancing Agent Long-Horizon Task Capabilities via Self-Evolving On-Policy Distillation : A team from the Department of Automation at Tsinghua University has proposed the Self-Evolving On-Policy Distillation (SEED) framework. The framework allows agents to autonomously summarize their task execution trajectories (whether successful or failed) into “hindsight skills” and distill these experiences back into the policy model with token-level precision by comparing decision differences with and without skill guidance. Experiments show that SEED significantly improves success rates and generalization capabilities in long-horizon tasks such as embodied interaction and web navigation. (Source: 36氪, arXiv:2607.14777)
Tencent BAC Proposes ProLaViT Framework, Achieving Progressive Visual Reasoning for Multimodal Large Models in Latent Space : Addressing the bottleneck where multimodal large models make errors in complex spatial and logical reasoning due to “swallowing information whole,” Tencent’s Content Services Department proposed the ProLaViT framework. Instead of relying on external visual experts, this method uses endogenous self-distillation to allow the model to gradually tighten its attention in a continuous latent space following the causal chain of “localization -> focus -> separation.” It also introduces a distance-weighted diversity loss during training to prevent representation collapse, significantly improving the model’s accuracy on fine-grained visual tasks such as puzzles and chart analysis.

New Paper Reveals Joint Scaling Laws of LLM Reasoning Capabilities from Pretraining to Post-Training : The paper “Understanding Reasoning from Pretraining to Post-Training” systematically studies the formation mechanism of LLM reasoning capabilities. The research shows that during model scaling, pretraining is the most effective stage for compute allocation initially; however, after reaching a certain bottleneck, compute should be tilted towards reinforcement learning (RL). Furthermore, the study points out that even if two models score the same on initial benchmarks, systematic differences in their learning potential (plasticity) during the post-training RL phase will exist due to differences in pretraining data distribution.

Study Reveals the “Severance Problem” of Personalized AI Assistants, Where More Memory Leads to Higher Hallucination Rates : The paper “LLMs are Unaware of the Person Beyond the Prompt” points out that personalized AI assistants suffer from a “Severance Problem.” Experiments found that as the personal information remembered by the AI assistant increases, the probability of generating incorrect or fabricated information rises from near zero to up to 11.7%. This occurs because the model tends to use fragments of memory to fill in the blanks about the user’s real-world state outside the chat window. Forcing the model to explicitly track the boundaries between “known” and “unknown” can effectively mitigate this phenomenon. (Source: TheTuringPost)
