Claude AI is a type of chatbot developed by Anthropic. It is designed to engage in natural language interactions and assist with various tasks including answering questions, writing, analysis, and coding.
"Anthropic [company] agrees to pay $1.5 billion to settle" a lawsuit by writers, according to media (September 2025).
Technology
Claude AI uses large language models (LLMs) based on the transformer architecture. These are big computer programs that learn from a lot of text to understand and create human-like language.
As of March 2024, the available models were:
- Claude 3 Opus: Anthropic's most capable model, designed for complex tasks requiring deep analysis and expertise
- Claude 3 Sonnet: A balanced model optimized for both performance and efficiency
- Claude 3 Haiku: A faster model designed for shorter, straightforward interactions
Anthropic designed Claude AI with a focus on safety and ethics, using a method called Constitutional AI. This ensures the chatbot aligns with principles that prioritize helpfulness, harmlessness, and honesty.
