Claude is a series of large language models (LLMs) developed by American software company Anthropic. Claude was released as an AI-based chatbot in March 2023. It is also used in AI-assisted software development. Anthropic sells Claude-based agentic tools including Claude Code, a terminal coding agent, and Claude Cowork, a similar tool for non-programmers.
Claude is trained using a constitution, a technique developed by Anthropic to improve ethical and legal compliance. Since Claude 3, each generation has typically been released in three sizes, named Haiku (the least capable), Sonnet, and Opus (the most capable). In 2026, a more capable model named Claude Mythos was released to a handful of companies and organizations; this was followed by the release of Claude Fable, a version of Mythos with stricter safeguards, to the general public.
Claude Code
Claude Code, released in February 2025, is an agentic command line tool to delegate coding tasks from the terminal using natural language prompts.[17] It was made generally available in May 2025 alongside Claude 4.[17][18] Based on enterprise adoption, Anthropic reported a 5.5x increase in Claude Code revenue by July.
GTG-2002
In August 2025, Anthropic reported that cybercriminals it designated "GTG-2002" had used Claude Code in a data-extortion campaign against at least 17 organizations.[24] In November 2025, Anthropic said that in September a China-based cybercrime group had used Claude Code to automate 80–90% of its espionage cyberattacks against 30 organizations.

Anthropic's Claude
Claude is a series of AI/LLM developed by Anthropic
Anthropic caused a bit of a stir when they did not fully release Claude to the general public as they said that it posed a too great a threat to Cyber Security.
In August 2025, Anthropic reported that cybercriminals it designated "GTG-2002" had used Claude Code in a data-extortion campaign against at least 17 organizations.
To call the Anthropic LLM just "Claude" is a little over-simplification. There have been various releases from March 2023 (Claude 1) up to Claude 5.5. (2026?)
