Fiddler AI

As an AI monitoring tool, Fiddler AI stands out by covering both LLM applications and traditional ML models in one platform, and by pairing observability with security.

Fiddler AI is an AI observability and security platform that monitors, explains, analyzes and protects models once they run in production.

Its feature list includes LLM and ML monitoring, alerts, segmentation, root cause analysis, visualization, custom metrics and reports.

The security side rests on Fiddler Trust Models, which watch for hallucinations, PII leaks and prompt injection attacks.

The platform is built for enterprises that want to ship predictive and generative models responsibly.

Pricing is enterprise, so expect to talk to sales rather than sign up with a card.

That fits a product built for larger teams running models in production, less so for a solo developer testing a prototype.
