On November 24, 2025 (local time), Anthropic, a U.S.-based artificial intelligence startup, made an official announcement regarding the release of its newest AI model, Claude Opus 4.5. Users can now access this model via Anthropic's dedicated application, API, as well as three major cloud platforms.

This model has garnered significant attention, being hailed as the top-performing model globally in areas such as coding, intelligent agents, and computer applications. It demonstrates a substantial edge over its competitors when it comes to everyday tasks, including in-depth research, slideshow creation, and spreadsheet management.

In the realm of agent-based programming, Opus 4.5 stands out by achieving cutting-edge performance. According to the SWE-bench benchmark, it surpasses both Google's Gemini 3 Pro, which was launched just last week, and OpenAI's GPT-5.1.

Moreover, two products that were previously in the pilot phase, Claude for Chrome and Claude for Excel, are now accessible to a wider user base.
