arXiv:2606.29424v1 Announce Type: new Abstract: Model routing balances solution accuracy and computational cost by selecting among models of varying capabilities. While recent multi-round frameworks interleave reasoning and planning, we identify a structural failure mode termed Trust Region Collapse. We demonstrate that the deep coupling of reasoning and routing, exacerbated by the dominance of strong pre-training priors under sparse supervision, leads to degenerate local optima where capable experts are systematically suppressed. To decouple these processes, we propose $\textbf{EntroRouter}$,
The proliferation of increasingly complex AI models necessitates more efficient and accurate routing mechanisms to balance performance and computational cost, leading to active research in this area.
Efficient model routing is crucial for scaling AI applications, optimising resource utilisation, and making advanced AI more accessible by managing cost-performance tradeoffs.
This research identifies and proposes a solution to a key challenge in multi-model AI systems, potentially allowing for more robust and resource-efficient AI agent architectures.
