Claude

Claude is a family of large language models developed by Anthropic that emphasizes safety, helpfulness, and harmlessness through constitutional AI training methodologies and advanced alignment techniques. Claude models, including Claude Sonnet 4 and Claude Opus 4, utilize transformer architectures enhanced with constitutional AI principles that train models to follow a set of principles and values while maintaining conversational abilities and task performance. These models incorporate techniques such as Constitutional AI (CAI), which uses AI feedback to train models according to a written constitution of principles, and Reinforcement Learning from Human Feedback (RLHF) to align model behavior with human preferences and values. Claude demonstrates strong performance across diverse capabilities including analysis, creative writing, code generation, mathematical reasoning, and multilingual understanding while maintaining robust safety measures and ethical guidelines. The models feature extended context windows, supporting complex document analysis and multi-turn conversations with enhanced memory and coherence. Claude is accessible through web interfaces, mobile applications, and API endpoints that enable integration into enterprise applications and developer workflows. These models are essential for organizations prioritizing AI safety, responsible deployment, and human-aligned AI systems that can handle sensitive tasks while maintaining appropriate boundaries and ethical considerations throughout interactions.
