command-a-plus-05-2026 is Cohere's first MoE model and their current flagship — it is the default model used in all code examples in the Cohere API reference. It supports 48 languages, vision input, and configurable reasoning budgets.
command-a-reasoning-08-2025 is a dense reasoning-optimized variant supporting 23 languages and agentic workflows, optimized for 4×H100 deployment.
