*Claude 4: Opus & Sonnet Redefine AI Coding Excellence* On May 22, 2025, Anthropic released Claude Opus 4 and Claude Sonnet 4, constituting the Claude 4 family of hybrid reasoning models that push state-of-the-art in coding and extended agentic workflows. These models set new records on coding benchmarks such as SWE-bench (72.5%) and Terminal-bench (43.2%) with sustained performance over long-horizon tasks. Claude Opus 4 can autonomously execute multi-step workflows for up to seven hours without performance degradation. Sonnet 4 succeeds the 3.7 model, balancing power, efficiency, and cost-effectiveness for everyday use cases. Both models introduce hybrid reasoning modes that allow seamless switching between near-instant responses and deeper “extended thinking” for complex problem solving.
