Choose LLMs-from-scratch if…

  • LLMs-from-scratch is primarily Jupyter Notebook; PROMPTPurify is TypeScript.
  • License: LLMs-from-scratch is Other, PROMPTPurify is MIT.
  • 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 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.

Choose PROMPTPurify if…

  • PROMPTPurify is primarily TypeScript; LLMs-from-scratch is Jupyter Notebook.
  • License: PROMPTPurify is MIT, LLMs-from-scratch is Other.
  • Tags unique to PROMPTPurify: ai-firewall, ai-safety, ai-security, application-security.
  • Also covers Computer Vision.

When NOT to use PROMPTPurify

  • 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.
