Anthropic's Opus 4.5 Model Set to Dominate Microsoft Excel

Anthropic’s Opus 4.5 Model is Here to Conquer Microsoft Excel

Hot on the heels of Google’s Gemini 3 Pro release, Anthropic has unveiled an update for its flagship Opus model, now at version 4.5. This new system promises state-of-the-art performance in coding, computer use, and office tasks, tapping into Claude’s historical strengths. The rollout includes a range of existing tools, plus an exciting new feature.

The company’s Chrome extension, Claude for Chrome, is now available to all Max users. Additionally, there’s a feature called infinite chat. This allows the chatbot to maintain context seamlessly across files and conversations, a highly-sought upgrade based on user feedback. One of the most exciting integrations is Claude for Excel, which embeds the chatbot into a sidebar of Microsoft’s app, now accessible to all Max, Team, and Enterprise users. With built-in support for pivot tables, charts, and file uploads, this tool aims to revolutionize how Excel is used.

Early testers have reported a notable 20% accuracy improvement and a 15% gain in efficiency when utilizing the Excel integration. This is particularly promising for users looking to streamline their spreadsheet tasks.

Moreover, Opus 4.5 is said to excel in refining workflows and is touted as Anthropic’s safest model yet, effectively repelling prompt injection attacks, even surpassing Gemini 3 Pro.

For those eager to explore the new capabilities, Opus 4.5 is available today through Anthropic’s apps and API, with developer pricing starting at $5 per million tokens.
