Updated through the day. Every headline links straight to the source. The two lines underneath are ours.
Token-level routing beats query-level routing on cost-quality, but only if you can actually implement it without tanking throughput. TokenRouter solves the hard part: the systems engineering. If you're running a multi-model serving infrastructure or building one, this moves from research idea to viable production pattern. The architecture choices matter more than the algorithm.
This is the kind of work that changes agent economics in production. Routing every step to Claude or GPT-4 wastes 60-80% of compute budget on subtasks that 7B models handle fine. AgentRouter's approach is practical: a 12M-parameter classifier with <5ms overhead that learns which steps need frontier reasoning and which don't. For builders running multi-step agents, this is immediately actionable. For cost-conscious teams, this flips the economics of when agents become viable. Implementation matters less than the insight: heterogeneous routing is now table stakes.
