Deploy it to production with 30 different SaaS integrations and suddenly your costs are 10x higher and latency is unbearable. Here’s why, and what Semantic Routing fixes. There’s a moment every team building production AI agents hits at exactly the same place. Your agent works great locally. You have Claude orchestrating tasks, calling tools, reasoning through problems. Perfect performance. Then you deploy to production where it needs to work with Salesforce, Jira, Workday, Slack, GitHub, and 25 other SaaS systems your customer uses. Suddenly everything breaks.

Half the time the agent picks the wrong API endpoint because it hallucinated which one to call. The other half it’s calling endpoints that don’t exist.
