Claude Sonnet 4.6

Claude Sonnet 4.6 is a multimodal foundation model engineered for high-performance agentic workflows, complex software engineering, and large-scale document analysis. As a central component of the Claude 4 model family, it utilizes a dense transformer architecture optimized for balancing computational efficiency with high-order reasoning capabilities. The model is specifically designed to function as a versatile workhorse for enterprise automation, supporting advanced tasks such as autonomous navigation of graphical user interfaces and multi-step agentic planning.

Technically, the model introduces several architectural innovations, including a beta 1-million-token context window that enables the processing of extensive codebases and multi-document datasets in a single inference pass. It features a hybrid reasoning framework that supports both adaptive thinking and extended thinking modes, allowing the model to dynamically allocate internal processing tokens for complex problem-solving. Furthermore, the inclusion of context compaction technology facilitates the efficient management of long-running conversations by summarizing historical context as it approaches architectural limits.

Performance is characterized by significant advancements in computer use, where the model demonstrates human-level proficiency in interacting with standard software environments, including web browsers and spreadsheets. It is highly optimized for the software development lifecycle, providing precise instruction following and a reduction in the common pitfalls of overengineering or output latency. The model is deployed via the Anthropic API and major cloud platforms, offering a scalable solution for developers requiring frontier-level intelligence for high-volume production applications.
