Nex-N1: Agentic Models Trained via a Unified Ecosystem for Large-Scale Environment Construction

AGI Team, Yuxuan Cai, Lu Chen +62

The evolution of Large Language Models (LLMs) from passive responders to autonomous agents necessitates a fundamental shift in learning paradigms -- from static imitation to incent…
