Frequently asked

How does budget control work?

Set a monthly USD limit. When spending approaches the limit, TruthProbe can auto-degrade to cheaper models or pause requests entirely. You choose the strategy.

Will my response quality suffer?

Only simple tasks (translation, classification, extraction) get optimized. Complex tasks always use your requested model at full power. You control the threshold.

Is my API key safe?

Your upstream API key is encrypted at rest. For maximum security, Enterprise plan offers private deployment where keys never leave your infrastructure.

Does it add latency?

Typical overhead is <50ms for complexity detection and routing. No caching layer means no staleness issues. The latency tradeoff pays for itself in cost savings.
