The HuggingFace Transformers library released version 5.9.0 on May 20, 2026, adding support for Cohere's new model architecture 'Cohere2Moe', which is described as Command A+ — a Mixture-of-Experts (MoE) language model from Cohere. The model features a hybrid attention pattern combining sliding window and full attention layers, shared and routed experts, and a very large context window. This indicates a new product launch from Cohere, expanding its model offerings with an MoE variant. The integration in a major open-source library increases the model's accessibility for developers and enterprises, potentially driving adoption. Source: HuggingFace Transformers v5.9.0 release notes.
