<p>The refactored system includes several cost optimizations:</p>
<ol>
<li class=""><strong>Hybrid Classification</strong>: Uses keyword matching before expensive LLM calls</li>
<li class=""><strong>Scale-to-Zero</strong>: Endpoints scale down when idle</li>
<li class=""><strong>Batch Processing</strong>: Supports bulk document classification</li>
<li class=""><strong>Caching</strong>: Frequently requested results can be cached</li>
<li class=""><strong>Small Workloads</strong>: Starts with small endpoints, scales on demand</li>
</ol>
<p>Estimated cost: <strong>~$0.10-0.50/hour for active endpoints</strong> (much less with scale-to-zero)</p>

<p>This refactoring transforms the Oral Health Policy Pulse from a standalone multi-agent system into a <strong>production-ready, enterprise-grade application</strong> that leverages Databricks' full stack for AI governance, deployment, and monitoring. The system now has:</p>
<ul>
<li class="">🏢 <strong>Enterprise deployment</strong> via Model Serving</li>
<li class="">📊 <strong>Automatic observability</strong> with MLflow tracing</li>
<li class="">🔐 <strong>Data governance</strong> through Unity Catalog</li>
<li class="">📈 <strong>Quality assurance</strong> with evaluation framework</li>
<li class="">💰 <strong>Cost optimization</strong> with scale-to-zero and hybrid approach</li>
<li class="">🚀 <strong>Production readiness</strong> out of the box</li>
</ul>
<p>All while maintaining backward compatibility with the standalone mode! 🎉</div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="row margin-top--sm theme-doc-footer-edit-meta-row"><div
