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 underlying models—which differ in performance and speed, 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 models are the engine inside. A new model can launch while the chat address stays 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 need to first figure out whether it means an app feature or a new model.

Claude is widely used to read and summarize long documents, polish writing, and work 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 was added that you can select or call via API within the same Claude product.

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