Humanity's Last Exam reveals the gap between AI and human intelligence despite rapid progress

Researchers created Humanity's Last Exam, a PhD-level AI benchmark with 2,500 questions designed to assess the limits of AI reasoning. Google's Gemini 3 Deep Think achieved the highest score at 48.4%, while human experts score around 90%. Despite progress, experts emphasize this doesn't signal the arrival of Artificial General Intelligence.

Harvard Study Shows AI Can Predict 71% of Fund Manager Trades, Raising Questions About Fees

A Harvard-led study reveals that AI can predict 71% of mutual fund trading decisions, suggesting much of active management follows detectable patterns. The research, analyzing data from 1990 to 2023, found that the unpredictable 29% of trades is where genuine alpha lives. The findings challenge the justification for high active-management fees and highlight how automation could reshape the $54 trillion asset management industry.

AI chatbots interpret 'likely' as 80% probability while humans assume 65%, new study reveals

A new study published in NPJ Complexity reveals that AI chatbots and humans interpret probability words differently, with language models assigning 'likely' to 80% while humans assume 65%. This probability misalignment poses risks in high-stakes fields like healthcare and government policy, where miscommunication about uncertainty could lead to flawed decisions.

Guide Labs open-sources Steerling-8B, a new interpretable LLM that traces every token to source

San Francisco startup Guide Labs has open-sourced Steerling-8B, an 8-billion parameter language model built with a novel architecture that makes every generated token traceable to its training data origins. Founded by Julius Adebayo and Aya Abdelsalam Ismail, the company aims to solve AI's black box problem by engineering interpretability directly into the model rather than analyzing it post-hoc.

AI agents surge in capability but lack safety disclosures, MIT AI Agent Index reveals

MIT researchers analyzed 30 AI agents and found a troubling pattern: while developers eagerly showcase what their systems can do, only 19% disclose formal safety policies and fewer than 10% report external safety evaluations. The study exposes how agentic AI systems that can autonomously perform tasks like booking flights and managing workflows are advancing faster than their safety frameworks.
