Hot on the heels of Google's Gemini 3 Pro release, Anthropic has announced an update for its flagship Opus model. Now at version 4.5, the new system offers state-of-the-art performance in coding, computer use, and office tasks. Claude, the AI behind Anthropic's success, has always excelled in these areas, so it's no surprise that Opus 4.5 continues to push the boundaries of what is possible.
One of the most exciting aspects of this update is the rollout of existing tools to a broader audience. For example, Claude for Chrome, the company's Chrome extension, is now available to all Max users. This will allow more people to experience the benefits of having Claude assist them in their daily tasks. Additionally, Anthropic is introducing a new feature called infinite chat, which ensures that the chatbot maintains consistency across files and chats, a highly requested feature from users.

Another significant update is Claude for Excel, which brings the chatbot directly into Microsoft's app. This tool is now available to Max, Team, and Enterprise users, with support for pivot tables, charts, and file uploads. Early testers have reported a 20 percent accuracy improvement and a 15 percent efficiency gain in their evaluations, showing the power of integrating AI into everyday tasks.

Opus 4.5 also excels in agentic workflows, with the new model being able to refine its own processes more effectively. Additionally, Anthropic is touting Opus 4.5 as its safest model yet, with improved security measures to protect against prompt injection style attacks.

If you're interested in trying out Opus 4.5 for yourself, it is available today through all of Anthropic's apps and the company's API. For developers, pricing for the new model starts at $5 per million tokens. With these updates and improvements, Anthropic's Opus 4.5 is set to conquer Microsoft Excel and revolutionize the way we work with AI technology.
