Diverse Open Model Releases: Cohere Command A+, NVIDIA Nemotron-3-Ultra, Zyphra ZAYA1, Poolside Laguna-M.1, and More
The open model ecosystem continues to diversify, with multiple organizations releasing new models this week. Cohere's Command A+ (218B-A25B MoE) is now under Apache 2.0 license and offers multimodal, multilingual, and agentic capabilities, usable on a single B200 GPU with 4-bit quantization. NVIDIA released Nemotron-3-Ultra-550B-A55B-BF16 under the OpenMDW license, a LatentMoE model that is faster than comparables. Other notable releases include Zyphra's ZAYA1-74B-preview MoE model, Poolside's Laguna-M.1 under Apache 2.0 (with a commitment to future open releases), and updated models from Zhipu (GLM-5.2), Moonshot AI (Kimi-K2.7-Code), and Stepfun (Step-3.7-Flash, strong in math). This breadth shows a shift from a few dominant players to a global, multi-actor open model landscape.
