## Choose when

### Choose AutoDefense if…

- Tags unique to AutoDefense: python.
- Also covers AI Agents, Inference & Serving.
- More GitHub stars (68 vs 25) - visibility, not fit.

### Choose IB4LLMs if…

- Tags unique to IB4LLMs: adversarial prompts defense, information bottleneck, jailbreak defense, llms protection.
- Also covers Evaluation & Observability.

## When NOT to use AutoDefense

- Last GitHub push was 177 days ago (slowing maintenance, Jan 15, 2026). Validate activity before betting a new project on AutoDefense.
- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use IB4LLMs

- Last GitHub push was 612 days ago (dormant maintenance, Nov 7, 2024). Validate activity before betting a new project on IB4LLMs.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
