What is Claude?

Claude AI is a family of large language models built by Anthropic, an AI safety company founded in 2021. Claude is used as a chat assistant, an API for developers, and an engine inside hundreds of third-party products. It is known for long context windows, strong writing quality, and careful reasoning on complex tasks. Claude is one of the three or four frontier AI models in regular use as of 2026, alongside OpenAI's GPT line and Google's Gemini.

Why it matters

Your buyers and your team are already using Claude — to draft strategy memos, summarize long PDFs, write code, and research vendors. When someone asks Claude about your category, the answer depends on what the model learned during training and what it can retrieve from the web at query time. Anthropic publishes the user agent for its crawler (ClaudeBot), so you can control access. Blocking it cuts you out of Claude's answers. Allowing it puts you in the running. Either way, the decision is yours — but pretending Claude is not a serious channel is a 2023 mindset in 2026.

How it works

Claude is built on the same transformer architecture as other modern LLMs but trained with Anthropic's Constitutional AI approach, which teaches the model to refuse harmful requests and explain its reasoning. Users interact through claude.ai, the API, the desktop and mobile apps, or developer integrations like Claude Code. Claude can handle context windows of hundreds of thousands of tokens, which means it can read a full book or a large codebase in a single prompt without losing the thread. When Claude needs current information, it uses tool calls to search the web, read URLs, or query connected systems via MCP. Enterprise customers run Claude through Anthropic's API, AWS Bedrock, or Google Cloud Vertex.
