Zumik vs LiteLLM
A widely used proxy and SDK that normalizes 100+ model APIs behind one interface.
Breadth and ubiquity. If you want a thin, self-hosted translation layer in front of many providers with minimal opinions, LiteLLM is hard to beat and free.
Zumik is not a translation layer. It treats reuse as a first-class measurable quantity, models agent state explicitly, and records reproducible routing and purge evidence. LiteLLM hands you a unified call; Zumik tells you what that call actually reused and what it cost to recompute.

| Purge receipts | Profile-specific evidence | No |
| Self-host | BYOC profile | Yes, core model |
Use LiteLLM when you want a free, self-hosted unifier across many providers. Use Zumik when repeated agent context is a real cost and you need to measure, reuse, and audit it.
