In plain words
Command A is a chat model from Cohere, a company that builds AI mainly for businesses. Cohere describes it as a model for answering from documents and for work tasks.
In chatmodel, that means it’s a good choice when you have a document and a question. Upload a PDF, ask what it says about something, and it answers from the text. It doesn’t understand photos or search the web, and it doesn’t take extra time to think before answering.
How to get the most out of it
- Upload the actual file. A PDF of the manual or the policy works much better than a photo of a page.
- Ask a specific question. “What’s the notice period?” beats “tell me about this”.
- Ask where it found the answer. “Quote the sentence” makes it easy to check.
- Ask for a table when you’re comparing two documents.
How it compares with the rest of the family
Command A is the only Cohere model in chatmodel, so its closest relatives are other models that read documents. Claude Sonnet 5 also reads documents and thinks before it answers. Mistral Large 3 is another option from a European company. Sonar Reasoning Pro reads documents and can check them against the web.
When to pick another model
For careful, personal writing, try Claude Opus 5. For numbers worked through step by step, pick a model that thinks before it answers. The PDF chat tool is a quick way to start with a document.
