Zilliz Cloud offers several cost control mechanisms for production agentic RAG, including autoscaling, query quotas, and tiered storage — all of which matter more for agentic workloads because autonomous retrieval loops can generate unpredictable query volumes.
The primary concern with agentic RAG costs is unbounded retrieval loops. If an agent iterates without a hard stop limit, it can issue dozens of Milvus queries per user request, multiplying your vector search costs by 10-20x compared to a simple single-pass RAG setup. The application-level mitigation is enforcing a maximum retrieval step count in your agent logic. On the infrastructure side, Zilliz Cloud's query metering gives you per-collection usage visibility so you can identify which agent workflows are generating disproportionate search volume.
Zilliz Cloud's tiered storage lets you move infrequently accessed collections to lower-cost object storage while keeping hot collections on fast NVMe-backed nodes. For agentic systems with large document archives — where the agent rarely retrieves documents older than 6 months — this can reduce storage costs by 60-80% without affecting retrieval quality for recent content.
Autoscaling ensures you don't overprovision for peak agent concurrency. Zilliz Cloud scales query throughput up during high-demand periods (batch agent runs, business hours) and scales down during off-peak times, paying only for the capacity you actually use.
