## Choose when

### Choose AI-Infra-from-Zero-to-Hero if…

- License: AI-Infra-from-Zero-to-Hero is MIT, modelz-llm is Apache-2.0.
- Tags unique to AI-Infra-from-Zero-to-Hero: llmsys, model-training, mlsys, genai.
- Also covers Inference & Serving.
- When you require detailed resource curation on ML systems and LLM infrastructures, as AI-Infra-from-Zero-to-Hero offers comprehensive information.

### Choose modelz-llm if…

- License: modelz-llm is Apache-2.0, AI-Infra-from-Zero-to-Hero is MIT.
- Tags unique to modelz-llm: llm, nlp, python, openai-api.
- Also covers Vector Databases.

## When NOT to use AI-Infra-from-Zero-to-Hero

- If you seek real-time support or interactive forums, as AI-Infra-from-Zero-to-Hero is primarily a resource repository without live assistance.
- For hands-on coding exercises or practical projects as the tool focuses mostly on curating resources like tutorials and academic papers but does not provide step-by-step coding guides.

## When NOT to use modelz-llm

- Last GitHub push was 1005 days ago (dormant maintenance, Oct 11, 2023). Validate activity before betting a new project on modelz-llm.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
