arXiv:2606.13241v1 Announce Type: new Abstract: Defining query difficulty is one of the hardest problems in deployment engineering. Existing LLM routers rely on surface features such as domain labels, keywords, and token count, ignoring the within-domain variance that actually determines model success. Frontier models cost ten to one hundred times more than local open-weight models, so at production scale even small per-request savings become a direct cloud-bill lever. We present Brick, a multimodal router that scores each model on six capability dimensions, combines this with a per-query diff
The increasing cost and sophistication of LLMs in production environments necessitate more efficient routing solutions, driving innovation in model selection and deployment.
Sophisticated LLM routing directly impacts operational efficiency and cloud expenditures for businesses relying on AI, offering significant cost savings and performance gains.
Deployment strategies for large-scale AI applications will evolve towards more dynamic, capability-based model selection rather than static or surface-feature-based routing.
