ZGCM-1: A Fully Open and Extremely Efficient Foundation Model for Math and Agentic Search A research team has released ZGCM-1, a fully open 7B dense foundation model trained from scratch for math and agentic search, built on the premise that compact models cannot passively memorize the open web but can overcome parametric capacity limits by coupling deliberate training with system and algorithmic efficiency. The model is described as achieving extreme data, system, and algorithmic efficiency. 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
