Task-Aware LLM Routing with Multi-Level Task-Profile-Guided Data Synthesis for Cold-Start Scenarios (2026.acl-long)
Copied to clipboard
| Challenge: | Existing routers generalize poorly in cold-start scenarios where in-domain training data is unavailable. |
| Approach: | They propose a task-type–aware router approach that models query-conditioned cost and performance via latent task-like variables with prior regularization derived from the synthesized task taxonomy. |
| Outcome: | The proposed framework improves performance and cost under cold-start and in-domain settings and enables efficient routing. |
