The open model ecosystem is diversifying beyond its previous Chinese dominance, with companies like NVIDIA, Cohere, Poolside, and Zyphra releasing models under permissive licenses. NVIDIA's 550B parameter Nemotron-3-Ultra uses LatentMoE architecture and switches to the OpenMDW license, while Cohere released Command A+ as a 218B-A25B MoE under Apache 2.0.

Zyphra has released ZUNA, an open-source model available on Hugging Face under the Apache 2.0 license. The model has been downloaded 529 times since its February 4, 2026 release.
