Is Chain-of-Thought Reasoning of LLMs a Mirage? A Data Distribution Lens

Researchers have found that large language models (LLMs) are poor at logical inference and generalizing beyond their training data, often producing "fluent nonsense" that can create a false sense of dependability. When tested on tasks that deviate from their training patterns, LLMs' performance degrades significantly, suggesting that their ability to reason is a "brittle mirage" that relies on pattern matching rather than true understanding.

AI Eroded Doctors' Ability to Spot Cancer Within Months in Study

A new study found that doctors who used artificial intelligence to help detect pre-cancerous growths in the colon saw their ability to spot tumors drop by about 20% after the AI assistance was removed, suggesting that reliance on AI can erode doctors' skills in as little as a few months. The study highlights the potential risks of over-reliance on AI in medicine, where human skills and judgment are still essential for accurate diagnoses.

AI agents fail tasks 70% of the time

Researchers have developed a benchmark called TheAgentCompany to evaluate the performance of AI agents in completing real-world professional tasks, such as browsing the web, writing code, and communicating with coworkers. The results show that the most competitive AI agent can complete 30% of tasks autonomously, indicating that while simpler tasks can be automated, more complex tasks are still beyond the capabilities of current AI systems.
