## Choose when

### Choose latent-jailbreak if…

- Tags unique to latent-jailbreak: large language models, latent jailbreak, output robustness, text safety.
- When conducting detailed safety assessments of text generation from LLMs like BELLE, ChatGLM2, and ChatGPT

### Choose fast-llm-security-guardrails if…

- Tags unique to fast-llm-security-guardrails: agentic-ai, ai-agent, ai-agents, ai-runtime.
- Also covers AI Agents.
- Fast integration of privacy and security guardrails in environments where real-time evaluation and observability are critical.

## When NOT to use latent-jailbreak

- If quick performance testing without in-depth safety analysis is the priority
- When working exclusively with smaller or less complex models that do not exhibit latent jailbreak behavior

## When NOT to use fast-llm-security-guardrails

- If your project requires a more customizable solution than what fast-llm-security-guardrails offers in its out-of-the-box configurations.
- For teams that operate without established runtime environments like LangChain or LlamaIndex, as this may necessitate significant adaptation of ZenGuard.
