About Claude Opus 4.6

Claude Opus 4.6, from Anthropic, is a hybrid reasoning and large language model. Launched February 5, 2026, it excels at software engineering, complex multi-step workflows, and enterprise tasks. Key features include a one-million-token context, adaptive thinking with effort controls, and agent teams.

Key Features

One-million-token context window in beta.

This lets the model handle a huge amount of information at once. You can upload entire codebases or review long legal documents. It helps users avoid losing track of important details across many pages of text.

Adaptive thinking with effort controls.

Claude can now decide how much "thinking" it needs to do for a task. You can pick from different effort levels. This means it won't overthink simple tasks, saving time and money.

Context compaction (beta).

This feature helps with long conversations. It summarizes old parts of the discussion as it goes. This means conversations can go on much longer without the model's performance dropping.

Agent teams in Claude Code.

Imagine multiple AI agents working together. One might do front-end code, another checks for security, and a third writes documentation. They all work at the same time, coordinating on their own.

128,000 maximum output tokens.

The model can now produce much longer responses. It can finish bigger tasks in one go instead of needing multiple requests. This means more complete answers and less breaking up your work.

Advanced agentic capabilities.

Claude Opus 4.6 is better at planning and working independently. It can break down complex tasks, use tools in parallel, and find problems with great accuracy. It stays focused and works well for long periods.

Frequently Asked Questions

It's built for tasks needing top-level intelligence like professional software engineering, complex workflows, and high-stakes enterprise tasks.

Instead of just answering questions, it acts as its own agent to break down tough problems, use tools at the same time, and stay reliable for hours on end.

It can process a lot more information at once. This lets you upload entire codebases, review long contracts, and analyze lots of reports without losing important details.

It's now the top performer on agentic coding, complex reasoning, and valuable knowledge work tasks, meaning it does better on finance, legal, and similar jobs.
