Fiddler Trust Service for LLM Observability and Security
AI Observability and Security is the foundation which gives enterprises the confidence to ship more predictive and generative models and LLM applications into production safely and responsibly.
Integral to the platform, the Fiddler Trust Service includes a series of purpose-built, fine-tuned Fiddler Trust Models that enable high quality LLM monitoring, scoring in live environments with the fastest guardrails in the industry. For added security, the Fiddler Trust Service can be deployed in cloud or VPC environments, ensuring enterprises maintain strict data control and safeguard LLM applications.

Fiddler Trust Models Deliver
Why Enterprise Leaders Choose the Fiddler Trust Service for LLM Monitoring
- Fastest: With a <100ms latency, the models are optimized for rapid scoring, monitoring, and guardrails, ensuring enterprises can quickly detect and resolve LLM issues.
- Cost-Effective: Trust Models are task-specific, optimized for efficiency and accuracy, while minimizing computational overhead.
- Secure: Fiddler can be deployed in cloud or VPC environments, maintaining compliance and protecting sensitive data.
- Scalable: Built to support high-volume enterprise workloads, Fiddler Trust Service handles over 5 million requests per day out-of-the-box.
Fiddler Trust Service: Quality and Moderation Controls for LLM Applications
The Fiddler Trust Service is an enterprise-grade solution that enables efficient use of computational resources and helps control costs compared to other LLM-as-a-judge offerings.
It combines two main scoring approaches: Fiddler Trust Models and LLM-as-a-judge. Together, they deliver 50 LLM metrics out-of-the box and custom metrics, powering guardrails, LLM monitoring, and agentic monitoring for secure enterprise deployments.
Fiddler Trust Models
In-house built models that provide fast, cost-effective, accurate and secure LLM scoring and metrics.
The Fiddler Trust Models are a series of proprietary, task specific models that score LLM prompts and responses based on hallucination, and toxicity, and jailbreak metrics. Compared to closed source foundational models, they provide highly accurate, cost effective, low latency scoring for a broad range of LLM metrics.
Enterprises can also create their own metrics by submitting prompts to the Fiddler-hosted Llama 3.1 8B model to address domain-specific use cases and specialized requirements. This fully-managed solution handles 300K+ daily events without the burden of infrastructure management.
Fast, Cost-Effective, and Secure Monitoring of 50 LLM Metrics
Fiddler Guardrails
LLM safety mechanism that moderates risky prompts and responses in real-time before they cause damage.
At <100ms latency, Fiddler Guardrails is the fastest in the industry. It leverages the scoring of the Fiddler Trust 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.
