Anthropic Claude Sonnet 5 Powers Up Dev Tools

Anthropic has quietly rolled out Claude Sonnet 5 as the new default AI model for its Pro, Team Standard, and Enterprise subscription tiers. This move positions Sonnet 5, known for its strong coding and tool-use capabilities, at a more accessible price point.

The upgrade brings a native 1 million token context window, a significant leap for handling extensive codebases or complex documentation. Adaptive thinking is also enabled by default, allowing the model to dynamically adjust its reasoning process.

Claude Code's Expanding Feature Set

Beyond the model upgrade, recent Claude Code updates highlight continuous development. The latest Week 28 digest introduces an in-app browser for the desktop version, enabling Claude to interact with live web pages for research or debugging.

A new /doctor command provides comprehensive setup diagnostics and can automatically fix identified issues. Auto mode enhancements now include blocking transcript tampering and requiring explicit confirmation for destructive commands like rm -rf on unresolved variables.

Agent management sees improvements with agent view rows displaying colored status indicators and AI-generated headlines for quicker comprehension.

Broader Availability and Tooling

Claude in Chrome is now generally available across all direct Anthropic plans. Subagents are designed to run in the background by default, allowing Claude to continue tasks without user intervention.

Linux users can access Claude Desktop in beta on Ubuntu and Debian. The platform also introduces /radio for a lo-fi Claude FM experience.
