# Anthropic Launches Claude Sonnet 5, Its Biggest Mass-Market AI Model Yet

> Anthropic's Claude Sonnet 5 is now the default model for Free and Pro users worldwide, offering near-Opus performance at introductory pricing.

Anthropic released Claude Sonnet 5 on July 1, 2026, marking the company's largest mass-market model launch of the year. The model is now the default for every Free and Pro user worldwide and is also available to Max, Team, and Enterprise customers through Claude Code and the Claude Platform.

Sonnet 5 is billed as the most agentic Sonnet model yet, capable of making plans, using tools like browsers and terminals, and completing tasks autonomously — performance that Anthropic says approaches its flagship Opus 4.8 model on many tasks. Cybersecurity safeguards are enabled by default, using the same real-time threat-detection protections as Opus 4.7 and 4.8.

Pricing starts at an introductory $2 per million input tokens and $10 per million output tokens through August 31, 2026, undercutting the previous Sonnet 4.6 generation, before rising to standard rates of $3/$15 per million tokens.
