Question 1

What is Lemma?

Accepted Answer

Lemma is an intelligent self-hosted AI gateway that intercepts LLM calls to provide semantic caching, complex query routing, and an automated privacy firewall. It helps developer teams scale AI applications efficiently.

Question 2

How does Lemma reduce LLM API costs?

Accepted Answer

Lemma routes simple requests to smaller, highly cost-effective models (like Gemini Flash or GPT-4o-mini) and serves up to 65% of repeated or semantically equivalent questions directly from a local 50ms vector semantic cache, dramatically slashing outbound API fees.

Question 3

What is an LLM Privacy Firewall?

Accepted Answer

An AI privacy firewall intercepts outbound prompt payloads to detect, mask, or scrub sensitive customer PII (Personally Identifiable Information) and API keys before they reach external LLM endpoints, ensuring corporate compliance with GDPR and HIPAA.

Question 4

Is Lemma open-source?

Accepted Answer

Yes, Lemma has a fully open-source, MIT-licensed core available via npm. Professional and cloud sync features are available in Lemma Pro.

Question 5

Who built Lemma?

Accepted Answer

Lemma is developed and maintained by Nxus Studio, a premium software engineering and AI consultancy boutique based in Guadalajara, Jalisco, Mexico.
