Claude

Claude is Anthropic’s flagship AI assistant, built from the ground up with safety, accuracy, and genuinely helpful reasoning as core design goals rather than afterthoughts. Available on the web, desktop, iOS, and Android, Claude excels at nuanced writing, in-depth analysis, complex coding tasks, and long-context work that requires holding large amounts of information in mind simultaneously.

Claude 3.5 Sonnet and Claude 3 Opus represent the current generation of Anthropic’s models. Sonnet offers an exceptional balance of speed and intelligence for everyday professional tasks, while Opus pushes further into graduate-level reasoning and extended multi-step projects. All Claude models have best-in-class context windows — up to 200,000 tokens — allowing you to paste in entire codebases, legal documents, or research papers and ask precise questions about them.

Where Claude stands out is honesty: it will tell you when it doesn’t know something, push back on questionable premises, and avoid making things up just to sound confident. This makes it particularly trustworthy for research, fact-checking, and sensitive professional tasks.

Claude’s constitutional AI approach also makes it notably willing to engage with nuanced, complex topics without excessive refusals. For teams, Claude for Teams and the Enterprise plan add SSO, audit logs, extended context, and dedicated support.
