Frequently asked questions

How does the Prompt Injection Guardrail work?
The engine evaluates input text against known semantic jailbreak patterns, instruction override markers, and role manipulation tactics before passing to upstream LLMs.
Can we configure custom blocked words or prohibited topics?
Yes. You can supply custom keyword lists and sensitive topic rules alongside standard safety models.
What is the latency overhead of running moderation on every user input?
Moderation is a single API call that usually completes in 1 to 2 seconds, so it fits into synchronous comment and chat flows.
Does the API provide category-specific breakdown scores?
Yes. The response breaks down probability scores across toxicity, hate speech, sexual content, violence, and prompt injection.
Can we customize the strictness threshold for different user tiers?
Yes. You can pass sensitivity parameters ("low", "medium", "strict") depending on whether your platform is gaming, general SaaS, or child-safe.
