Claude
Claude is an assistant for conversational work, web research, files and code. It is available through web, desktop and mobile applications. Free access has limits, and paid subscriptions expand usage and tools. A Claude subscription does not fund general developer API requests: that requires a separate Console account and billing arrangement.
Editorial Overview
Claude is a large language model developed by Anthropic, an AI safety company founded in 2021. The model is designed with a focus on helpfulness, honesty, and harm avoidance, and is trained using techniques informed by Constitutional AI, Anthropic's proprietary alignment methodology. Claude is used for tasks including long-form writing, document analysis, coding assistance, and nuanced reasoning. It is particularly well-regarded for its ability to handle lengthy input documents and maintain coherence across extended conversations. Anthropic positions Claude as a safety-conscious alternative in the competitive large language model market. It is available directly via Claude.ai for end users and via API for developers building on top of the model.
How it works
Claude processes text conversations through a chat interface or via API. It accepts large context windows, allowing users to paste in full documents, codebases, or research papers for analysis. Each response is generated based on the full conversation history provided. Claude is available in multiple versions targeting different speed and capability trade-offs.

How It Compares
Claude's primary differentiator against ChatGPT is its context window size and safety emphasis. It is often preferred for document-heavy tasks where full-text input is necessary. Against Google Gemini, Claude has stronger independent third-party usage but less Google Workspace integration. It is a common enterprise consideration alongside ChatGPT for teams with strict output reliability requirements.
