Dynamic Model Routing: Cutting LLM Spend Without Cutting Capability
Most enterprise LLM spend isn't a model-selection problem; it's a routing problem. A reference architecture for AI gateways and the four places they break.

FinOps & Routing Questions Answered
How does dynamic semantic model routing reduce enterprise LLM spend by 60–80%?
Empirical enterprise telemetry shows 70–80% of production prompts involve routine classification, summarization, or structured extraction. A sub-10ms pre-generation classifier routes routine tasks to quantized open-weight models (such as Qwen 3.8-27B or GLM-5.3-Flash) while reserving expensive frontier reasoning APIs strictly for complex multi-step synthesis.
What is the VRAM parking tax in enterprise GPU clusters?
Dedicated GPU instances provisioned for peak daytime concurrency often sit at <15% utilization overnight and across fragmented departmental clusters—creating a 60% idle VRAM tax. Multi-Instance GPU (MIG) partitioning, prefix-aware continuous batching, and shared sovereign inference gateways maximize HBM3e utilization.
How do you attribute LLM token costs per tenant and business unit?
By injecting OpenTelemetry baggage headers (tenant_id, cost_center, workflow_id) at the deterministic model gateway, every prompt token, completion token, and cached prefix hit is metered in real time and exported to FinOps chargeback ledgers.
