Logical Intelligence Achieves 76 Percent on Putnam Benchmark, Highlighting Shift Beyond Large Language Models to Language-free, Mathematically Grounded Models2.12.2025 15:15:00 CET | Press release
Over the last decade, artificial intelligence (AI) has been largely built around large language models (LLMs). These systems are based on a language and guess words in a chain in the form of tokens. As a result, they frequently hallucinate and require vast compute and power infrastructure to solve tasks. The moment systems like public safety, national infrastructure, and industrial automation need logic, LLMs break and introduce safety risks. Token-free language independent models represent a new direction for AI. They do not predict words. They search for correct solutions and require less compute. Logical Intelligence is the first company building exclusively around mathematically derived, non autoregressive EBM (Energy Based Model) reasoning. Today, Logical Intelligence announced that its Aleph tool achieved a 76 percent score on the Putnam Benchmark, one of the most demanding mathematical reasoning tests in artificial intelligence. The benchmark measures a model’s ability to solve

Invisible IT Emerges as Workplace Transformation Evolves, Lenovo Research Finds2.12.2025 15:00:00 CET | Press release
Four out of five IT leaders say their systems can’t keep up and are turning to AI-powered automation to make IT seamless, predictive, and proactive. The next step in workplace transformation is invisible technology that fades into the background so that support is automated and seamless, according to a Lenovo global survey of IT leaders released today. Most employees only notice IT when it slows them down and interrupts processes. Invisible IT is the opposite. It means technology that anticipates needs, prevents issues before they happen, and personalizes support automatically. Achieving Invisible IT, the newest report in Lenovo’s ongoing Work Reborn series, explores how AI and automation are redefining the digital workplace and employee experience. Of the IT leaders who participated, 79% aspire to deliver seamless, proactive support that minimizes disruption for employees, but only 21% have achieved predictive issue resolution.
