Learn about Claude Opus 4.6's capabilities, features, and how it can help you achieve better results.
The New Frontier of Intelligence
Claude Opus 4.6 represents a significant leap in large language model capabilities, specifically engineered for the most demanding cognitive tasks. Released on February 5, 2026, it introduces Adaptive Thinking, a breakthrough feature that allows the model to dynamically scale its reasoning effort based on query complexity. This ensures that while simple queries remain efficient, complex logic puzzles and high-stakes engineering tasks receive the deep processing they require.
Built for the Agentic Era
Designed to go beyond simple chat, Opus 4.6 is a powerhouse for autonomous agentic workflows. With industry-leading scores on Terminal-Bench 2.0 and SWE-Bench Verified, it can navigate computer environments, manage multi-step software debugging, and orchestrate complex projects with minimal human intervention. Its expanded 1 million token context window (available in beta) allows it to hold entire technical ecosystems in memory simultaneously.
