Discover Claude Opus 4.6

What's New and Improved?

Released on February 5, 2026, Claude Opus 4.6 by Anthropic boasts significantly enhanced coding capabilities and complex task handling over its previous versions (theverge.com).

Key Features

• 1 Million Token Context Window (Beta): This feature can handle lengthy documents or large codebases, making it perfect for extended conversations and complex projects (theverge.com).
• Agent Team: Create small AI teams for code reviews or parallel processing tasks, efficiently managing even the largest codebases (theverge.com).
• Intelligent Reasoning and Planning: Executes plans with precision, performs self-debugging, and improves errors seamlessly (anthropic.com).

Making It Easy for Beginners

Understanding the 'Context Window'

The context window is the number of characters the AI can process at once. It means that even with extensive documents, Opus 4.6 can instantly understand and respond.

What is 'Agent Team'?

Think of it like having a team of assistants, each taking on a specific task and combining their efforts. For example:

• One AI analyzes the code
• Another runs tests
• Yet another summarizes errors This collaborative process enhances efficiency and accuracy.

Adjusting 'Effort Levels'

The /effort setting allows you to decide how deeply the AI thinks:

• Choose from low, medium, high, max based on your needs, enabling quick handling of simple tasks and thorough execution of complex ones (anthropic.com).

Real-World Example: Detecting Security Vulnerabilities

In trials, Opus 4.6 identified over 500 high-risk security issues in open-source libraries. Its ability to comprehend code logic allows it to deduce problems like a human (techradar.com).

Example: Suppose repetitive attacks arise from unchecked input validation; Opus 4.6 learns and examines similar code spots autonomously.
