About this tag
Model routing refers to the practice of intelligently selecting which AI model to use for a given task, balancing factors like cost, speed, and capability. On WindowsForum, discussions cover how enterprises like Anthropic and Microsoft are implementing model routing to optimize AI deployments. Topics include using cheaper models for routine tasks while reserving frontier models for complex work, as highlighted by Microsoft CEO Satya Nadella's warning against "tokenmaxxing." Real-world examples, such as Glean's $1 million monthly AI agent cost, illustrate the economic importance of routing. The tag also covers open-weight models and policy-controlled coding models like MAI-Code-1-Flash, which enable cost-effective, governed AI use in enterprise environments.
