Command R+vsAya Expanse

Command R+, developed by Cohere, is an enterprise-grade model with 104 billion parameters and a 128K token context window, purpose-built for retrieval-augmented generation and tool-use workflows. The model excels at grounded generation with faithful document citation, multi-step tool use, and enterprise search applications. Its advanced RAG capabilities produce responses that accurately synthesize information from provided sources with proper attribution. Command R+ supports multilingual enterprise workflows and structured data extraction. Priced at $2.50 per million input tokens and $10.00 per million output tokens. As an open-source model, it can be deployed on enterprise infrastructure for data-sensitive applications. Command R+ ranks #17 on the Chatbot Arena leaderboard, reflecting strong enterprise-focused capability. It is the preferred choice for organizations building AI-powered knowledge management and document analysis systems.

Aya Expanse, developed by Cohere through the Cohere For AI research initiative, is a multilingual open-source model with 32 billion parameters and a 128K token context window supporting 23 languages. Building on Aya 23, it substantially extends context length and improves quality across diverse languages. The model demonstrates strong cross-lingual transfer, enabling tasks like translation, summarization, and question answering across language pairs with limited parallel training data. Its 128K context window makes it suitable for processing long documents in languages where few other models offer extended context. Free and open-source, Aya Expanse aims to democratize access to capable multilingual AI. The model is particularly valuable for researchers and organizations working in lower-resource languages that receive minimal attention from major commercial AI providers.
