Claude 3 is a family of large multimodal AI models developed by Anthropic, with a focus on safety, interpretability, and user alignment. The models, which include Opus, Sonnet, and Haiku, excel in reasoning, math, coding, and multilingual understanding. They are designed to be helpful, honest, and harmless assistants and can process text, audio, and visual inputs. Claude 3 models use Constitutional AI principles, aiming for more ethical and reliable responses. They have improved abilities in long context comprehension, and have shown strong performance in various tests, often outperforming previous Claude models and sometimes matching or exceeding GPT models in some benchmarks.
