Claude 3.5 Sonnet v2 is Anthropic's enhanced version of the breakthrough Claude 3.5 Sonnet, delivering significantly improved coding capabilities, longer context handling, and more reliable tool use at the same competitive pricing. It maintains the same 200K-token context window while achieving substantial gains in HumanEval, SWE-bench, and agentic task completion rates. Claude 3.5 Sonnet v2 remains widely used as a fallback model for teams that have standardized on the 3.5 architecture and prefer its consistent, well-characterized behavior for production deployments.
