# Claude Sonnet 5 Released

> Anthropic has released Claude Sonnet 5, positioning it as its most capable intermediate model and the new default for both free and paid users on Claude and inside Claude Code. The headline pitch is agentic: better planning and tool use, paired with a 1 million token context window that lets it hold large codebases or document sets in view at once. The company is also dangling introductory pricing of $2 and $10 per million input and output tokens through August 31, after which it climbs to $3 and $15. Two details are worth sitting with. Anthropic says Sonnet 5 shows a lower rate of undesirable behaviors than the previous Sonnet 4.6, and that it has been deliberately kept weak at cybersecurity tasks, a rare case of a lab advertising a capability it chose not to sharpen. For most people this lands as a straightforward upgrade to the model they already use, but the pricing and the default-model status are the real story: this is the tier that will quietly power a huge share of everyday AI work.
