Claude Opus 4.6
Anthropic's most capable AI model, optimized for complex coding, long-running tasks, and enterprise workflows with a 1M token context window.
What is Claude Opus 4.6?
Claude Opus 4.6 is Anthropic's most intelligent AI model, built for complex coding, multi-step reasoning, and handling tasks that need sustained attention over hours.
It has a 1 million token context window (roughly 700,000 words), which means it can read and work with massive codebases, long documents, or entire project histories in a single conversation.
Most builders use it for agentic coding tasks where the AI needs to plan, execute, and iterate on complex problems. It's particularly strong at understanding requirements, writing production-quality code, and handling multi-file changes. You can access it through Claude.ai (Pro/Team/Enterprise) or via the API.
Pricing starts at $5 per million input tokens and $25 per million output tokens. Prompt caching can reduce costs by up to 90% for repeated context.
