claude-opus-4-8

Claude Opus 4.8 is Anthropic's most capable generally available model in the Opus family. It supports text, image, and file inputs with text output, featuring reasoning capabilities and a 1M-token context window. It is ideally suited for highly autonomous agents, long-horizon agentic work, knowledge work, and memory-driven tasks where coherence over extended sessions is critical. The model excels particularly at multi-step reasoning, complex coding, and end-to-end project orchestration—handling large codebases, multi-stage debugging, and long-running asynchronous agent pipelines. Beyond coding, it manages knowledge work such as drafting documents, building presentations, and analyzing data, consistently maintaining high quality across very long outputs.
