anthropic/claude-opus-5.5
The successor to Opus 5 and Anthropic's recommended default model, built for long-running agentic coding and knowledge work. The official price drops to $4 / $20 per million tokens (from $5 / $25), and cache reads cost just 5% of the input price. Thinking is always on — tune its depth and cost with the effort parameter (default medium). 1M-token context window, text and image input, and native prompt caching.
