Claude

Claude is the family of AI assistants built by Anthropic. Like other large language models, Claude can write and edit text, answer questions, analyse documents, and help with coding, all through plain-language conversation.

Anthropic offers Claude in several tiers, from free access to paid Pro, Max and Team plans, and through an API that developers use to build Claude into their own products. The line-up usually includes models tuned for different trade-offs between speed, cost and raw capability.

Claude is designed with a strong emphasis on safety and predictable behaviour, and it powers a growing range of tools, from the Claude Code programming assistant to research apps like Claude Science. For readers of this site, Claude is one of the reference points against which other models are often measured.
