Enterprise teams now have a way to build custom reasoning agents without breaking the bank. A new method called RLSD cuts compute costs while improving model performance, making advanced AI accessible to more businesses.
Sally Kornbluth, MIT’s president, highlights how federal funding cuts and endowment taxes threaten America’s research pipeline. She argues that basic science is the bedrock of future breakthroughs in AI, medicine, and quantum computing—and warns the consequences could last for decades.
Before fine-tuning, every top large language model spends weeks learning grammar, facts, and patterns from vast text corpora. Discover how pre-training establishes the raw capability that later human feedback refines into useful AI.
Shift, an AI startup, is offering complimentary home cleaning services across New York City this summer. In return, it will record cleaners in action to build datasets for training household robots.
A German startup now offers free professional cleaning in New York City, but participants must allow on-site recording to train household robots. The unusual service raises privacy and data use questions.
Agentic AI systems often fail due to misaligned feedback signals in reinforcement learning. A new technique called SDAR introduces a gated self-distillation method that provides precise, step-level guidance without destabilizing training.
A collaboration between MIT, Georgia State, and community colleges is creating hands-on AI training pathways to close the skills gap for entry-level roles and current workers in industries from fintech to healthcare.
