AI governance has transformed trust and security while human oversight remains focused and minimal
In a recent project and task, I showcase how we use Fiddler AI's key features like AI observability and monitoring, which track hundreds of metrics across traditional machine learning models and large language models to monitor performance, data drift, and accuracy. We use it as security and guardrails that implement real-time safety measures to block harmful outputs and protect against jailbreak and prompt injection attempts. We also utilize it for explainability, helping teams understand why an AI model made a specific prediction or decision, providing deep root cause analysis when problems occur. Lastly, we employ it for governance and compliance, creating centralized audit trails and model cards to help companies meet strict regulatory standards and risk management requirements. Fiddler AI has significantly impacted my organization positively, particularly in security and guardrails. As we use many tools, we previously had humans monitoring all of them. Human errors created loopholes, but now with Fiddler AI, which is trained using our company policies and playbooks, human intervention has become minimal. We have reduced human intervention by 70% and human mistakes by around 90%, which are the points I wanted to mention. Reducing human intervention by 70% directly affects our productivity and day-to-day work. A person who worked with one policy or guardrail for a week now hardly takes one day, saving us six days of effort for each cycle. Moreover, the reduction in human mistakes has significantly improved product quality, with great feedback from vendors and other businesses using the product, increasing confidence levels and scores when using Fiddler AI.

Monitoring multi-agent LLM workflows has become reliable and protects PII in real time
WhyLabs's best features are real-time guardrails, PII personal information data detection, hallucination mitigation, and monitoring. It has a centralized dashboard so I can create a project and see an overall summary of the dashboards, and I can check the health metric on specific dates or specific times for WhyLabs or for the application. Additionally, it provides an alerting system. If there is an error or the system is down, it generates an alert via email. Out of all those features, I find the PII detection and the monitoring most valuable in my day-to-day work because it is very hard to monitor an LLM application. As I mentioned earlier, it was a multi-agent system and a query can go from one agent to another agent very easily, which created problems in debugging how the request was progressing and how the data flow was happening. The monitoring and the PII detection of the guardrails are the three features most useful to me. Regarding the guardrails or the PII detection, if I do not want my PII data given to the agents or any LLM, this feature is particularly useful in that scenario. WhyLabs has positively impacted my organization by reducing the error time and debugging time. It has increased and enhanced the user experience. When the application is down, I receive alerts, which has reduced a significant amount of time for my team.
