đź’ˇ Quick Take for Searchers: If you’re looking for “Claude 3.1 Opus,” you’re actually looking for the Claude 4.6 series, which has officially superseded the older 3.x models as of March 2026. Anthropic launched Claude Opus 4.6 in February 2026, and it is currently the most intelligent AI model available in the US for complex reasoning, autonomous agent tasks, and long-horizon coding. With a 1M token context window, native computer use capabilities, and interactive visual connectors, Opus 4.6 has become the go-to for enterprise-grade research and high-level strategy. This guide covers the verified March 2026 features, pricing for Pro/Max plans, and how to access the “Computer Use” research preview.
🚀 Why “Claude Opus 4.6” Is the Intelligence Leader (March 2026)
While the 3.1 era focused on foundational improvements, the 2026 Claude 4.6 update represents a generational leap. Claude Opus 4.6 isn’t just a chatbot; it is a reasoning engine designed for “Agentic Workflows”—tasks where the AI plans, executes, and refines its own steps to achieve a goal.
âś… Opus 4.6 “Deep Thinking”: Features an Adaptive Thinking mode that allows the model to “pause and reason” internally before responding. It consistently outperforms all competitors in graduate-level reasoning (GPQA) and complex coding.
âś… 1 Million Token Context: Opus 4.6 now supports a massive 1M token window generally available, allowing you to upload entire codebases, 2,000-page documents, or dozens of financial reports for a single analysis.
âś… Computer Use (Research Preview): Pro and Max users can now allow Claude to “use” a computer—opening files, navigating web browsers, and using dev tools to perform multi-step tasks autonomously.
âś… Interactive Visuals & Apps: Claude can now generate and run interactive apps (charts, diagrams, and live data visualizations) directly inside the chat, allowing for real-time data manipulation.
âś… Memory & Personalization: Now available for all tiers (including free), Claude remembers your style, past projects, and specific preferences to provide a more tailored experience over time.
