Anthropic releases Claude Sonnet 5 as cheaper agentic alternative to Opus and competing models

According to TechCrunch, Anthropic released Claude Sonnet 5 positioned as a lower-cost model with agentic capabilities that can make plans, use tools like browsers and terminals, and run autonomously at a level previously requiring larger models. The release reflects a shift across the industry where agentic capability is becoming a baseline expectation at every price tier rather than a premium differentiator.
