You can use Fiddler AI to monitor, evaluate, and protect enterprise artificial intelligence agents and machine learning models in production. It checks incoming prompts and outgoing responses in real time to catch jailbreaks, sensitive data leaks, and toxic content before they reach users or internal networks. The system tracks accuracy, latency, and token consumption across your entire fleet of agents. You can run automated evaluations locally without calling external language models, maintain full compliance audit trails, and debug problematic behaviors across testing and deployment stages.
