About Claude

Claude is an AI assistant created by Anthropic that excels at analysis, writing, coding, and having nuanced conversations. It's known for being helpful, harmless, and honest.

Overview

Claude is an advanced AI assistant developed by Anthropic, founded by former OpenAI researchers with a mission to build safe, interpretable AI systems. The latest Claude 4 family, released in 2025, includes Claude Sonnet 4.5 (world's best coding model as of October 2025), Claude Opus 4.1, and Claude Haiku 4.5 (which now powers the free tier with near-frontier performance). What sets Claude apart is its exceptional ability to handle complex analysis tasks, process extensive documents with up to 1M token context windows, and maintain nuanced, context-aware conversations while prioritizing safety and accuracy. In 2025, Claude introduced groundbreaking features including Claude Code (agentic coding assistant), Claude Skills (workflow automation), extended thinking with visible reasoning, and computer use capabilities that allow Claude to control desktop environments. Claude excels particularly in research-heavy tasks, detailed content analysis, and sophisticated coding challenges. With the world's best coding performance (Sonnet 4.5) and ability to run autonomously for 30+ hours on complex tasks, Claude is the preferred choice for professionals dealing with large documents, complex technical problems, and tasks requiring deep analytical thinking. The AI demonstrates remarkable reasoning abilities with extended thinking, showing its work and explaining its thought process step-by-step. Claude is known for refusing to hallucinate, admitting knowledge gaps when uncertain, which builds trust and reliability for professional use.
