## 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 Aquila2 if…

- Aquila2 is primarily Python; LLMs-from-scratch is Jupyter Notebook.
- Tags unique to Aquila2: llm, llm-inference, llm-training, python.
- Also covers Inference & Serving.

### Choose LLMs-from-scratch if…

- LLMs-from-scratch is primarily Jupyter Notebook; Aquila2 is Python.
- 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.

## When NOT to use Aquila2

- Last GitHub push was 639 days ago (dormant maintenance, Oct 11, 2024). Validate activity before betting a new project on Aquila2.
- 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.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

## 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丰
- a deeper learning experience.
