The frontiers of AI research advance with the MindTopo benchmark, Anthropic's progress on the Riemann hypothesis, and techniques for extracting internal LLM reasoning.

Analysis

[Anthropic] achieved meaningful progress on the Riemann hypothesis with an unreleased AI model ^[2]

• Substantially raised the lower bound on the 150+ year-old unsolved math problem
• the Riemann hypothesis
• 60 subagents collaborated to test 650 ideas
• consuming 31 million output tokens
• Two in-house Anthropic mathematicians verified the work
• formalized using the open source Lean proof assistant

[Microsoft Research] released MindTopo, a benchmark evaluating spatial reasoning capabilities of multimodal models ^[1]

• Evaluates five topological reasoning capabilities: connectivity
• closure
• order
• separation
• and knots
• Found that performance drops significantly on sequential action-based planning compared to static image recognition
• Highlights the need for developing reliable AI in robotics and interactive environments

[University of Tübingen research team] developed a technique for extracting hidden reasoning processes from frontier AI models ^[4]

• Demonstrated that hidden reasoning traces can be extracted from API models by OpenAI
• Anthropic
• and Google
• Moonshot AI's Kimi K3 produced outputs similar to the reasoning of Claude Opus 4.8 and GPT 5.6 Sol
• Also found vulnerabilities leaking personal information such as passwords and API keys (now fixed)

[MIT Technology Review] reported on next-generation LLM architecture trends beyond Transformer limits ^[3]

• Google's transformer
• published in 2017
• has begun to become a bottleneck after 9 years
• The dense attention mechanism becomes exponentially expensive as text volume grows
• Presents 4 new architectural ideas that could significantly improve speed and efficiency

[AI2050 Program] convened academic AI researchers to discuss new realities and role redefinition ^[3]

• An AI research support initiative from Schmidt Sciences sponsored by Eric and Wendy Schmidt
• Runs a fellow program with participation from prominent scholars in the AI field
• Discussed new realities facing university AI researchers
