Anthropic Unveils Faster, Cheaper AI Model: Claude Sonnet 5.5

Anthropic has released Claude Sonnet 5.5, a significant upgrade over its predecessor. The new model offers 30% faster performance and up to 30% lower costs for most tasks. It excels in everyday tasks like bug fixing, document creation, and design, making it a complement to the more complex Claude Opus 5.5. Sonnet 5.5 also improves in coding, scoring 70.6% on Terminal-Bench 4.0 compared to Sonnet 5’s 10.3%, and performs well in knowledge work, nearly matching Opus 5.5 on real-world tasks. The model is priced the same as Sonnet 5 but is more efficient, requiring fewer tokens per task. It also includes enhanced cybersecurity safeguards and alignment improvements, making it suitable for a broader range of applications.
