- Ce qui s'est passé
- TRACE-Router routes agentic AI tasks to different LLMs once at admission, then pins all calls to that model, updating routing policy using final task outcome.
- Pourquoi ça compte
- Enterprise engineers deploying multi-model AI systems where task-level accuracy and latency matter more than optimizing individual LLM calls independently.
- Vigilance
- Paper is recent preprint with limited real-world deployment data; effectiveness depends on having meaningful delayed task-level feedback signals available.

Abstract: Routing to select large language models (LLMs) with different cost-quality trade-offs has become a fundamental deployment feature of enterprise AI. Existing routers, primarily make independent routing decisions for each LLM call. However, agentic applications execute as long-horizon workflows whose quality is determined only by a delayed, task-level outcome. This mismatch prevents per-call routers from correctly attributing feedback to individual routing decisions. Towards mitigating this, we present TRACE-Router, a task-level routing framework that aligns routing with the unit of supervision. TRACE-Router assigns each task to a model once at admission using a contextual bandit, pins all subsequent LLM calls to the selected backend, and updates its policy using the task's terminal reward, jointly accounting for accuracy and latency. By leveraging delayed task feedback,
