Artificial Intelligence (AI) is one of the most important and most discussed topics of our time. Nowadays, there are many powerful models–but only a few focus on security, ethics and transparency as consistently as Claude. It goes beyond mere efficiency and focuses on a crucial question: How can AI act reliably, trustworthy and responsibly?
This guide aims to clarify how Claude can be used, what strengths it has and for which use cases it is best suited.
What is Claude?
Claude is an AI-powered text and code generator developed by the US company Anthropic. It was named after Claude Shannon, the father of information theory. Similar to ChatGPT from OpenAI or Gemini from Google, Claude helps users to compose texts, write code, summarize information or analyze data. Claude’s focus is primarily on security, ethics and user-friendliness.
Anthropic was founded in 2021 by former OpenAI employees. Anthropic's goal is to develop “responsible AI”. The company pursues a constitutional AI approach: Anthropic's AI models learn to behave safely, helpfully and ethically based on predefined principles.
How does Claude work?
Claude is based on Large Language Models (LLMs) trained on billions of text data. The technical basis is similar to a GPT (Generative Pretrained Transformer) but differs in the training approach: While classic LLMs are often optimized based on human feedback (e.g., via Reinforcement Learning with Human Feedback, RLHF), Claude also uses constitutional guidance called "Constitutional AI". This provides rules and ethical principles as guidelines according to which the model independently evaluates decisions. Through strict self-regulation, advanced filtering mechanisms and a deep understanding of context, Claude minimizes the risk of misinformation, bias and harmful content without sacrificing precision or versatility.
