How Cygnal Protection Works

When Cygnal detects policy violations, it automatically prevents harmful content from being generated. Instead of potentially dangerous responses, it returns safe refusal messages and marks the finish_reason as violation:

{
  "finish_reason": "violation", 
  "index": 0,
  "message": {
    "content": "Sorry, I can't help with that.",
    "refusal": "Sorry, I can't help with that.",
    "role": "assistant",
  }
}
