Choose pmetal if…
- pmetal is primarily Rust; LLMs-from-scratch is Jupyter Notebook.
- Tags unique to pmetal: ane, apple-silicon, distillation, fine-tuning.
- Also covers Inference & Serving.
When NOT to use pmetal
- 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.
Choose LLMs-from-scratch if…
- LLMs-from-scratch is primarily Jupyter Notebook; pmetal is Rust.
- Tags unique to LLMs-from-scratch: artificial-intelligence, attention-mechanism, finetuning, from-scratch.
- - You are an advanced practitioner aiming to fully understand the underpinnings of LLMs using PyTorch as your primary framework.
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.
