Question 1

Does Overrule add latency to LLM calls?

Accepted Answer

Policy evaluation runs locally in under 1ms — no network hop, no cold start. Your LLM call takes 200-500ms. Overrule adds less than 0.5% overhead. Unlike proxy-based solutions, we never sit between you and your provider.

Question 2

Will SDK failure break my application?

Accepted Answer

Never. Fail-open architecture means if Overrule has an issue, your AI keeps running. Governance errors log silently — they never throw, never block, never crash your production.

Question 3

How is Overrule different from Lakera, Guardrails AI, and NeMo Guardrails?

Accepted Answer

Most alternatives are either expensive SaaS proxies that route your data through their servers ($50K+/yr), or open-source libraries with no audit trail. Overrule is the first to combine an open-source SDK (runs in your infra) with a cloud audit dashboard (proves compliance to regulators). You get enterprise-grade governance at startup-friendly pricing.

Question 4

Can I self-host Overrule?

Accepted Answer

The SDK is MIT-licensed and runs entirely in your environment. Policy evaluation is 100% local. The cloud dashboard is optional — it stores your audit trail and gives you visibility.

Question 5

Does Overrule support streaming LLM responses?

Accepted Answer

Yes. Overrule is the first AI governance SDK to offer token-by-token policy evaluation on streaming responses via guard.stream(). Violations are caught mid-stream, not after the full response completes.

Question 6

Does Overrule integrate with LangChain?

Accepted Answer

Yes. Overrule provides OverruleCallback — a drop-in LangChain callback handler that governs every LLM call in any chain, agent, or tool with one line of code. No other governance SDK integrates at the framework level.
