Prompt monitoring

The ongoing tracking and analysis of the prompts (inputs) sent to an AI system—along with the model's responses—to detect misuse, policy violations, security risks, performance issues, or drift in how the system is being used

The Explain card

Plain English
Prompt monitoring is the ongoing tracking and analysis of the inputs sent to an AI system, together with its responses, to spot misuse, policy violations, security risks, performance problems or drift in how people use it.
Example
A company's monitoring dashboard flags a spike in prompts containing "ignore your instructions" from one account, revealing an employee probing the assistant for its hidden system prompt.
Why it matters
Prompts are the attack surface of a language model. Without watching them, jailbreaks, data exfiltration attempts and abusive usage stay invisible until the damage is public.
Hook
Read the mail coming in, not just the replies going out.
