# Claude Sonnet 5 Launches as Production-Ready Agentic Model

> Anthropic has made Claude Sonnet 5 the default model across its Free and Pro tiers, positioning it as the workhorse most people will actually use day to day. The pitch is simple: performance that lands close to the far pricier Opus 4.8, but at a fraction of the cost. Through the end of August it runs at two dollars per million input tokens and ten dollars per million output, rising to three and fifteen after that. The real story is where Sonnet 5 is aimed. Anthropic built it for agentic work, the kind of multi step jobs where a model drives a browser, runs commands in a terminal, and completes tasks on its own rather than answering a single question. That capability used to require the biggest, slowest models, and Sonnet 5 claims to do it cheaply enough to run at scale. Anthropic also says the safety picture improved over Sonnet 4.6, with fewer hallucinations and better resistance to prompt injection, the attack where hidden instructions hijack an agent. For anyone deploying assistants that touch real tools, those two numbers matter as much as raw benchmark scores.
