Computer Use
Computer use has been one of the biggest problems and security vulnerabilities for every AI model. Not every organization or company has workflows that can adapt to computer use, so preparatory work, such as building bespoke connectors, is necessary. However, after a long observation and development process, the Anthropic team enabled the Claude Sonnet 4.6 model to perform human-like computer operations with a virtual keyboard and mouse. Sonnet 4.6 can navigate a complex spreadsheet, fill out a multi-step web form, create a presentation or documentation from scratch, manage multiple browser tabs, and perform web-related tasks. Although the Claude Sonnet 4.6 model still lags behind the computer use of a skilled human, it offers much more advanced computer use compared to its predecessors.
Claude Sonnet 4.6 Performance
The Claude Sonnet 4.6 model has outperformed the Sonnet 4.5 model in all benchmarks. This statistic indicates that the Claude Sonnet 4.6 model surpasses the Sonnet 4.5 model in every aspect. The fact that the model's version and performance have increased while its pricing has remained the same makes it one of the best value-for-money LLM choices. Furthermore, the Sonnet 4.6 model shows slightly lower or higher performance than its competitors in different benchmarks.
Although Sonnet 4.6 lags behind Opus 4.6 in most benchmarks, it managed to outperform both Opus 4.6 and its competitors, Gemini 3 Pro and GPT-5.2, in the Finance Agent v.1 benchmark used for Agentic Financial Analysis and the GDPval-A A Elo benchmark used for Office Tasks.
