Abstract Claude is a large language model (LLM) developed by Anthropic, a safety-focused AI company founded in 2021. First introduced to the public in March 2023, Claude has rapidly evolved from a cautious conversational assistant into one of the world’s most capable and widely deployed AI systems. This paper is an updated version of Jaiswal and Medlen (2024), revisiting Claude’s capabilities, architecture, and societal implications in light of the dramatic advances that have occurred since that original publication. As of March 2026, Claude is powered by the Claude 4.6 family, comprising Opus 4.6, Sonnet 4.6, and Haiku 4.5, offering a 1-million-token context window, advanced reasoning, coding, vision analysis, computer use, and agentic task completion through tools such as Claude Code and Claude Cowork. This paper explores Claude’s underlying Constitutional AI framework, its practical applications in education and professional settings, its limitations and ethical considerations, including questions of trust, bias, and safety, and its potential to empower underserved communities, including women and students worldwide. Situated within the broader landscape of AI assistants, including ChatGPT, Gemini, and Wenxin Yiyan, Claude represents a distinctive approach to building AI that is simultaneously powerful, honest, and safe.
