## Decision facts: LLMs-from-scratch

- **Adopt for:** LLMs-from-scratch is a project-oriented repository aimed at building PyTorch-based language models from the ground up, with detailed step-by-step instructions.

## Choose when

### Choose LLMs-from-scratch if…

- LLMs-from-scratch is primarily Jupyter Notebook; llm-pruning-collection is Python.
- License: LLMs-from-scratch is Other, llm-pruning-collection is Apache-2.0.
- Tags unique to LLMs-from-scratch: ai, artificial-intelligence, attention-mechanism, deep-learning.
- - You are an advanced practitioner aiming to fully understand the underpinnings of LLMs using PyTorch as your primary framework.

### Choose llm-pruning-collection if…

- llm-pruning-collection is primarily Python; LLMs-from-scratch is Jupyter Notebook.
- License: llm-pruning-collection is Apache-2.0, LLMs-from-scratch is Other.
- Tags unique to llm-pruning-collection: jax, llm-evaluation, llm-training, pruning.
- Also covers Developer Tools.

## When NOT to use LLMs-from-scratch

- - If you are looking for a rapid deployment of an LLM without understanding its intricate structure - this tool requires extensive manual and conceptual work.
- - You prefer frameworks with automatic model generation or other high-level abstractions that simplify the process. This repository emphasizes manual creation, which is more time-consuming but offers
- a deeper learning experience.

## When NOT to use llm-pruning-collection

- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- 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.
