# Claude Sonnet 5 Becomes Default Model, Agentic Capabilities Near Opus Level

> Anthropic has quietly made a big call: Claude Sonnet 5 is now the default model for Free and Pro users everywhere, not the flagship Opus. The pitch is that this mid-tier model lands close to Opus 4.8 on many tasks while costing about a third as much, with introductory pricing of $2 per million input tokens and $10 per million output tokens running through August 31. It arrives built for agentic work, with tool use, browser control and terminal access, a 1 million token context window and up to 128K tokens of output. The signal here is less about a single benchmark and more about where the frontier is heading. When the cheaper, faster model is good enough to be everyone's default, the economics of building on top of it change sharply. For most people writing code, drafting, or wiring up automated workflows, Sonnet 5 is the model they will actually touch. The temporary pricing is the catch worth watching, since the real cost of running these agents day to day only shows up once the introductory window closes.
