# Claude Sonnet 5 launched as most agentic mid-tier model

> Anthropic has released Claude Sonnet 5, and the headline is that mid-tier no longer means mid-capability. The company says the model reaches near-Opus 4.8 performance while staying in Sonnet's cheaper price class, with introductory pricing of $2 and $10 per million input and output tokens through August 31. What Anthropic is really selling is autonomy. Sonnet 5 can plan multi-step tasks on its own, drive browsers and terminals, and see workflows through to completion, with clear gains over Sonnet 4.6 in reasoning, tool use and coding. That combination of agentic behavior at a workhorse price is aimed squarely at developers building products on top of these models. The move matters because cost is what decides whether agentic AI gets deployed at scale. A model that acts like a frontier system but bills like a mid-tier one changes the math for anyone running agents in production, and it keeps pressure on rivals to match both the capability and the price.
