Anthropic has released Claude Opus 4.5, the newest version of its flagship AI model. The upgrade brings stronger reasoning, better coding performance, faster agent workflows, and tight integrations with Google Chrome and Microsoft Excel, making it one of the most practical AI releases for both developers and business users.

Smarter, Faster, and More Capable

Opus 4.5 delivers major improvements in long-form reasoning and coding tasks and scores above 80 percent on the SWE-Bench Verified benchmark. Anthropic says the model handles ambiguous tasks more reliably and helps teams complete longer workflows with fewer iterations. It is also priced more competitively, making top-tier AI performance more accessible for professionals and enterprises.

New Integration: Claude for Excel

Anthropic has launched a dedicated Excel sidebar that allows Opus 4.5 to read, analyze, clean, and build spreadsheets. It can fix formulas, generate financial models, and automate repetitive data tasks, saving hours for analysts and finance teams.

New Integration: Claude for Chrome

A new Chrome extension lets Claude assist directly inside the browser. It can navigate webpages, extract data, fill forms, and support research or admin tasks. The extension is available to Claude Max users and is built on Opus 4.5’s improved “computer use” abilities.

Why It Matters

With faster agents, productivity-focused features, and deep integration into two of the world’s most-used tools, Claude Opus 4.5 is designed to act as a true digital coworker. The release strengthens Anthropic’s push into enterprise AI, giving users a safer, more reliable, and more capable assistant for coding, analysis, and daily workflow automation.
