Zoo Labs Foundation is a 501(c)(3) nonprofit advancing open-source AI research, frontier model development, and decentralized science.
Advance open AI research by building frontier models, publishing research papers, and developing tools that make AI accessible to researchers worldwide.
45+
Frontier models from 600M to 480B parameters, all open weights
7
Published research in HLLM, DSO, and formal verification
102
Community-governed improvement proposals
Founded in 2021, Zoo Labs Foundation started with the belief that frontier AI should be open, verifiable, and community-governed. Not locked behind corporate walls.
We built the Zen model family on Qwen3+ architecture: 45+ models spanning text, code, vision, audio, video, and 3D generation. Every model has open weights on HuggingFace.
Our research spans Hamiltonian Large Language Models (HLLMs), decentralized semantic optimization (DSO), and 15 formally verified proofs in Lean 4. We publish everything open access.
Zoo Gym, our training platform, has enabled thousands of researchers to train and fine-tune models at 99.8% lower cost through Training-Free GRPO.
Open weights, open papers, open code. Closed AI is a dead end for science.
15 Lean 4 proofs. Every critical system machine-checked, not hand-waved.
102 ZIPs. Research direction decided by contributors, not executives.
Zen-guard safety models. Alignment research integrated, not bolted on.
Developing the Zen family of open-source models. From 600M parameter edge models to 480B parameter frontier systems, all with open weights on HuggingFace.
