Anthropic Unleashes Opus 4.5: Excel Integration & ‘Infinite Chat’ for Enterprise AI

Anthropic has launched Opus 4.5, an AI model focused on enhancing workplace productivity, particularly through deep integration with Microsoft Excel. Key features include the full rollout of Claude for Excel, which embeds a chatbot in Excel's sidebar, supporting tasks like pivot tables and chart creation. Early testers reported a 20% increase in accuracy and a 15% improvement in efficiency. The new Infinite Chat feature allows for coherent memory across long conversations, addressing the 'goldfish memory' issue.

Opus 4.5 is claimed to be the safest model yet, outperforming competitors in resisting prompt-injection attacks. It is available across all Anthropic apps and APIs, with API pricing starting at $5 per million tokens.
