Anthropic has officially launched Claude Sonnet 5.5, the newest iteration of its flagship model family built to handle deeply complex, long-horizon multi-step tasks. The model features significantly improved native agentic capabilities, allowing it to autonomously plan, execute, and verify code execution and data manipulation across entire software pipelines. Enhanced security controls and hardened safety guardrails have been baked directly into the architecture to mitigate risks like prompt injection and unexpected autonomous behavior. Early enterprise benchmarks indicate substantial performance gains in software engineering, complex data analysis, and cross-application tool orchestration compared to previous generations.
