Yandex has introduced an automated routing system for Alisa AI that dynamically selects the appropriate model based on user query complexity. For routine tasks, the system prioritizes speed, while complex requests involving multi-step planning, calculations, or document analysis trigger the Expert mode.

The Expert mode allows users to monitor the AI's reasoning process and upload multiple files for simultaneous analysis. This mode is currently available to all users without restrictions. Yandex plans to limit high-frequency usage of these advanced features to subscribers of the Alisa Plus service in the future.

The underlying architecture utilizes a proprietary agent harness, a technological layer that enables the AI to manage context, plan actions, and interact with external services or tools. This system ensures that the AI can effectively handle specialized queries in fields such as finance, law, medicine, and travel planning.
