Rethinking Quality in Large Language Model Routing: Security-Conditioned Model-and-Budget Selection
Security-conditioned LLM routing ensures sensitive queries are not cost-optimised onto weaker models—a design consideration enterprises with mixed-sensitivity workloads should integrate into their model-serving architecture.
Summary written by editorial AI · Source link below
arXiv:2610.18566v2 Announce Type: replace-cross Abstract: Large language model (LLM) routers reduce serving cost by choosing which model to call and how many output tokens to grant it for each query. Existing routers rank model-budget actions using a single quality metric. This does not work for mixed workloads. For ordinary queries, a good answer is correct and useful (utility); for security-sensitive queries, a good answer refuses harmful requests or resists malicious instructions (security).
Editorial Analysis
Enterprises running multi-model LLM stacks risk routing security-sensitive prompts to less guarded models if their routers optimise only for cost and latency.
Review your LLM routing policies to confirm that query sensitivity is an explicit routing criterion, not just cost and quality.
