# ZGCM-1: A Fully Open and Extremely Efficient Foundation Model for Math and Agentic Search > Source: > Published: 2026-09-15 03:30:01+00:00 In this work, we present ZGCM-1, a fully open 7B dense foundation model trained from scratch with extreme data, system, and algorithmic efficiency. ZGCM-1 is founded on a core premise: compact models cannot passively memorize the open web, but can overcome parametric capacity limits by coupling deli
