Building the Mixture-of-Models for the next era of computing.

Research Frame

The next era of computing will not be organized around one model. It will be a changing pool of large and small, open and closed, local and cloud intelligence.

My work is about making that diversity usable as one system. A user should choose an objective—speed, cost, balance, or accuracy—while semantic routing decides the capability path across models, tools, memory, verifiers, hardware, and locations.

  • Preference-aligned Mixture-of-Models gives applications one stable model contract while the system handles execution.
  • Semantic routing turns workload signals and policy into inspectable decisions across a changing model pool.
  • Workload–Router–Pool co-design connects semantic demand with live serving state, cache, placement, and heterogeneous hardware.

I pursue this work in the open through vLLM Semantic Router, research, and collaboration across the inference ecosystem.
