Intro

What is Fiddler AI?

Fiddler AI is an enterprise-grade AI observability and security platform designed to monitor, explain, and protect LLM applications and machine learning models. As organizations work to deploy and observe LLMs in enterprise with NVIDIA TensorRT-LLM and Fiddler, the platform highlights model monitoring importance to ensure reliable performance. Often compared to other solutions in the MLOps space, such as Arize AI or Arize Phoenix, Fiddler provides deep visibility and audit trails to help teams build ethical, compliant practices using the Fiddler compliance dashboard. Driven by robust Fiddler AI funding, the company continues to expand and innovate, offering new opportunities for data scientists and engineers interested in Fiddler careers or Fiddler AI careers. Ultimately, Fiddler helps businesses keep a vigilant eye on production systems, serving as a reminder to teams: don't let your model's quality drift away.

Fiddler AI FAQ

Accuracy can be highly misleading when dealing with imbalanced datasets because a model could achieve a high accuracy score simply by guessing the majority class while completely failing to predict the minority class. Fiddler monitors imbalanced data, feature drift, and predictive impact to provide a more holistic evaluation.
