Model routing is becoming a key component of the enterprise AI stack, dynamically sending prompts to the right AI model to optimize speed and costs. However, current frameworks mostly treat routing as a static classification problem, which severely limits their potential.A new open-source framework called Agent-as-a-Router tackles this bottleneck, treating the router as a dynamic, memory-building agent. It uses a Context-Action-Feedback (C-A-F) loop to track model successes and failures and update the behavior of the router. The researchers also released ACRouter, a concrete implementation of this paradigm. In their tests, ACRouter significantly outperformed static routers and the expensive strategy of defaulting to premium models, all without requiring teams to train massive models or wr [...]
