Claude

Claude is both a conversational AI service made by Anthropic and the name of the family of AI models that generate answers within it. The chat product you use on the website and app is called "Claude," and the models with different performance and speed levels — like Opus, Sonnet, and Haiku — are also called "Claude models."

Think of it like a car: the Claude app is the driver's seat and body, while the Claude model is the engine inside. Even when a new model comes out, the chat address may stay the same, and the same model can also run inside other services like Amazon Bedrock or Google Cloud. So when an article says "Claude was released," you first need to figure out whether it means a new app feature or a new model.

Claude is widely used for reading and summarizing long documents, polishing writing, and working with code. But like other generative AI, it can confidently state things that aren't true, so important numbers, dates, and quotes should be checked against the original source. Anthropic is the developer; Amazon and Google are investors and cloud distributors, not the makers of Claude.

"Anthropic unveiled a new Claude model" — this doesn't mean an entirely new chat service was created. It means a new engine has been added that you can select or call via API within the same Claude product.

1. Open a new conversation with a free account at claude.ai.
2. Paste in a short document or something you wrote and ask: "Break this down into a table of 3 key claims and any numbers that need verification."
3. After getting the result, follow up with: "Quote the exact source sentence for each number from the original text. If you can't find it, write 'unverifiable.'"
4. Try the same request with ChatGPT and compare the format, accuracy, and tone — this quickly shows which one fits your work better.
