Choose long-context-attention if…

  • long-context-attention is primarily Python; LLMs-from-scratch is Jupyter Notebook.
  • License: long-context-attention is Apache-2.0, LLMs-from-scratch is Other.
  • Tags unique to long-context-attention: ring-attention, python, llm-inference, pytorch.
  • Also covers Inference & Serving.

When NOT to use long-context-attention

  • 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.
  • Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.

Choose LLMs-from-scratch if…

  • LLMs-from-scratch is primarily Jupyter Notebook; long-context-attention is Python.
  • License: LLMs-from-scratch is Other, long-context-attention is Apache-2.0.
  • Tags unique to LLMs-from-scratch: deep-learning, ai, artificial-intelligence, attention-mechanism.
  • - 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丰
  • a deeper learning experience.
