Anthropic upgrades Claude with new Sonnet 5.5 model, details here

Anthropic’s Claude Sonnet 5.5 is positioned as a faster, more cost-effective upgrade to the company’s mid-tier model, delivering over 30% better speed and lower effective token usage while keeping the same list pricing. For CIOs and technology leaders, that improves the economics of enterprise AI for everyday coding, document generation, slides, and UI work, and the addition of Opus-like cybersecurity safeguards makes it a more viable option for broader, governed IT adoption.
