OpenAI Officially Releases 249-Page Paper and Verification Code for Astra Model Solving 10 Major Mathematical Problems : OpenAI has officially released a 249-page technical paper detailing how its next-generation reasoning model, Astra, solved 10 Fields Medal-level mathematical problems, and open-sourced the Lean 4 formal verification code on GitHub. Astra constructed the first counterexample to non-sofic groups and broke the decay rate limit for high-dimensional sphere packing problems that had stood since 1978. This breakthrough demonstrates AI’s profound constructive capabilities in pure mathematics, with the average token cost per proof being only $200, signaling the arrival of an era where “computing power buys mathematical theorems.” (Source: OpenAI News)

Andrej Karpathy Buzzes Over Claude Opus 5 Generating Full 3D Physics Game World from a Single Prompt : Former Tesla AI lead Andrej Karpathy made his first post since joining Anthropic, showcasing Claude Opus 5 generating a 3D game world of “The Lord of the Rings” complete with complex physics, textures, and music using just a single prompt within a 1-million-token budget. This progress marks a paradigm shift for AI from simple 2D SVG drawing to procedural 3D prototype generation. However, Karpathy also pointed out that due to the model’s lack of real-time video perception and game auditing capabilities, limitations such as clipping (objects passing through each other) in the generated visuals still exist.

Microsoft’s Cybersecurity System MDASH Achieves Breakthrough 95.95% Score on CyberGym Benchmark : Microsoft announced the latest results of its multi-agent cybersecurity system, MDASH, on the CyberGym benchmark, leading the industry by a wide margin with a 95.95% vulnerability reproduction rate. The system employs a highly cost-effective hybrid routing architecture: a lightweight model, MAI-Cyber-1-Flash, with only 5B active parameters, handles 90% of routine security queries, while only the most difficult 10% of tasks are offloaded to GPT-5.4. This halves inference costs while maintaining top-tier defense performance, demonstrating the evolution of AI cybersecurity from “stacking large models” to “systematic cost reduction.” (Source: 36Kr)
