Command A Reasoning vs Grok 4.3
Side-by-side specs, pricing and capabilities. Both models run on Clade under one subscription, so you can switch between them in the same conversation.
Command A Reasoning comes from Cohere and Grok 4.3 from xAI. The practical difference for most people is context, price, and which input types each one accepts.
