## Fiddler Guardrails: Frequently Asked Questions

### Deployment & Latency

**Q: Why am I getting much higher latencies than advertised?**

**A:** Fiddler Guardrails achieves its lowest latencies when requests are made to a Fiddler environment within the same network boundaries as your application. Network distance between your application and the Fiddler environment adds round-trip time.

Latency spikes can also occur due to temporary usage surges, even though we provision for peak capacity. If you’re consistently experiencing higher latencies, please contact us on the #fiddler-guardrails-support channel.

**Q: What does this error code mean? How do I fix it?**

**A:** Please visit the [Guardrails tutorials](/developers/tutorials/guardrails) for detailed information about error codes and their solutions.

### Service Features

**Q: What's included in Fiddler Guardrails?**

**A:** Fiddler Guardrails includes:

* Real-time safety moderation across 11 dimensions
* Faithfulness (hallucination) detection for RAG applications
* PII/PHI detection and redaction
* Integration options with NVIDIA NeMo Guardrails and LangChain

### General Information & Future Plans

**Q: What are Fiddler Centor Models?**

**A:** Integral to the Fiddler AI Observability and Security platform, Fiddler Centor Models are a series of proprietary, fine-tuned small language models (SLMs) that enable high-quality LLM monitoring and scoring in live environments with the fastest guardrails in the industry. For added security, Centor Models can be deployed in VPC or air-gapped environments, ensuring enterprises maintain strict data control and safeguard LLM applications.

**Q: How does Fiddler Guardrails use Fiddler Centor Models?**

**A:** At \<100ms latency, Fiddler Guardrails is the fastest in the industry. It leverages the scoring of Fiddler Centor Models to evaluate prompts and responses and moderate harmful outputs for hallucination, toxicity, and jailbreaks. Simply specify your desired metric thresholds and let Fiddler Guardrails handle the enforcement.

**Q: What languages are supported?**

**A:** Fiddler Guardrails currently only supports English. Based on user feedback, we're evaluating support for additional languages.
