Claude 3 Opus is Anthropic’s flagship AI model, released in March 2024 as the most advanced member of the Claude 3 family. It is designed for complex reasoning, open-ended dialogue, coding, and tasks requiring high accuracy across domains. The model is multimodal, supporting both text and image inputs, and features an expansive ~200,000-token context window, enabling it to process and reason over long documents and detailed multimodal content.
Compared to earlier Claude models, Opus demonstrates significant performance gains on reasoning and coding benchmarks, positioning it among the top large-scale models available. Common use cases include advanced problem-solving, long-form content analysis, multimodal research support, and AI-driven software development.
