## Choose when

### Choose 12-factor-agents if…

- 12-factor-agents is primarily TypeScript; IB4LLMs is Python.
- Pricing: Free to use with open-source licenses.
- Requirements: Min 4 GB RAM; Requires Docker; Requires a solid understanding of TypeScript and familiarity with concepts like prompt engineering and context window management..
- Tags unique to 12-factor-agents: 12-factor, agents, ai, context-window.
- Also covers AI Agents.
- You are specifically developing AI agents or LLM-powered applications in TypeScript and need a structured guideline grounded in the 12-factor app principles.

### Choose IB4LLMs if…

- IB4LLMs is primarily Python; 12-factor-agents is TypeScript.
- Tags unique to IB4LLMs: adversarial prompts defense, information bottleneck, jailbreak defense, llms protection.
- Also covers Evaluation & Observability.

## When NOT to use 12-factor-agents

- If your project requires languages other than TypeScript or if your application already has a strong foundation not necessarily aligning with the 12-factor app principles.
- When you’re looking for comprehensive deployment automation tools rather than guidance on building LLM-powered agents and ensuring their reliability in production environments.

## 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.
