Zen LM Team
Zen LM is a joint initiative of Hanzo AI (Techstars ‘17) and the Zoo Labs Foundation (501c3). We build and release open frontier models under the Zen model family — co-developed using the Zen MoDE (Mixture of Distilled Experts) architecture. Our goal is frontier capability with open weights, so any developer or researcher can run, fine-tune, and extend our models.
The Zen model catalog spans 600M to 480B parameters across text, vision, audio, and code modalities. All general-purpose Zen models are released under Apache-2.0.
