Uses AI agents to conduct structured evaluations of content, leveraging customisable prompts and system instructions for comprehensive assessment. Unlike rule-based compliance checks, this approach enables nuanced analysis by allowing agents to interpret content contextually based on predefined criteria.

​
a. Using Interface

Configuration Parameters
  • Model: Specifies the LLM model used for evaluation.
  • Eval Prompt: The main evaluation prompt that defines how the AI should judge the response.
  • System Prompt: A higher-level instruction that guides the AI’s evaluation behaviour.
