## Decision facts: rellm

- **Adopt for:** rellm is a Python tool that guarantees structured outputs from language model completions by leveraging the Hugging Face Transformers library.

## Choose when

### Choose generative-ai-for-beginners if…

- generative-ai-for-beginners is primarily Jupyter Notebook; rellm is Python.
- Tags unique to generative-ai-for-beginners: generativeai, dall-e, ai, generative-ai.
- More GitHub stars (113k vs 513) - visibility, not fit.

### Choose rellm if…

- rellm is primarily Python; generative-ai-for-beginners is Jupyter Notebook.
- Tags unique to rellm: llm, huggingface-transformers, transformers.
- - When you require precise and exact structure in output data generated from any language model, utilizing rellm can ensure consistency.

## When NOT to use generative-ai-for-beginners

- 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.

## When NOT to use rellm

- - Avoid using rellm if you are not working with the Hugging Face Transformers library or do not need structured output formats.
- - If your project can tolerate some level of unstructured or less rigidly formatted outputs from language models, other solutions might be more appropriate.
