Anthropic’s Claude is a family of large language models (LLMs) designed to assist with a wide range of tasks, from answering questions and summarizing documents to generating code and engaging in creative writing. Developed by Anthropic, a company founded by former OpenAI researchers, Claude aims to provide users with a conversational AI experience that is both helpful and aligned with ethical principles. Since its inception in March 2023, Claude has undergone several iterations, each enhancing its capabilities and performance.
What Is Claude?
Claude is an AI chatbot powered by large language models developed by Anthropic. It is designed to understand and generate human-like text, making it capable of performing various tasks such as summarization, question answering, code generation, and more. Claude is accessible through a chat interface and API, allowing users to interact with it in a natural, conversational manner. The model is trained using a unique approach called Constitutional AI, which aims to align the AI’s behavior with principles of helpfulness, harmlessness, and honesty. This approach reduces the reliance on extensive human feedback, focusing instead on guiding the model’s outputs through predefined ethical guidelines.

Ethical Considerations and Privacy
Anthropic places a strong emphasis on the ethical implications of AI. The Constitutional AI approach is central to ensuring that Claude’s outputs align with human values and ethical standards. Additionally, Anthropic has implemented measures to address privacy concerns
- Data UsageStarting October 8, 2025, Anthropic will begin using conversations users have with Claude as training data for its large language models, unless users opt out. This change aims to improve the accuracy and usefulness of AI responses. New users are prompted to decide on data sharing during sign-up, while existing users may have already encountered a pop-up with the new policy. By default, data sharing is enabled through a toggle labeled Help improve Claude in Privacy Settings. Users who do not opt out will have both new and revisited chats used for training, with reopened old threads becoming eligible for training as well.
- Data RetentionAnthropic has updated its data retention policy, extending the storage of user data from 30 days to five years. This policy applies to all non-commercial users-both free and paid-whereas commercial, government, and educational users remain exempt.
Global Reach and Adoption
Claude’s adoption has been widespread, with a significant user base both in the United States and internationally. Notably, nearly 80% of Claude’s consumer usage originates outside the U.S., with countries like South Korea, Australia, and Singapore demonstrating higher per-capita usage than America. The company, valued at $183 billion and backed by Alphabet and Amazon, has seen significant business growth due to the strength of its AI models, particularly in coding capabilities. Claude’s business user base has surged from fewer than 1,000 to over 300,000 in two years, and company revenue skyrocketed from $1 billion to over $5 billion in just eight months of 2025. As part of its global expansion, Anthropic plans to triple its international workforce and open new offices in Dublin, London, Zurich, and Tokyo to meet the growing demand for its AI models.
