How do you control OpenAI API costs at scale?
Prompt caching, semantic caching of full responses, model routing (cheap model first, escalate on uncertainty), output length limits, batch API for non-real-time workloads, and per-tenant token budgets.
How is data handled when calling OpenAI from our app?
We use OpenAI's no-train enterprise endpoints, redact PII before egress, scope API keys per environment, and route through a gateway that gives you full audit logs for every prompt and response.
