Choose LLMs-from-scratch if…
- LLMs-from-scratch is primarily Jupyter Notebook; OpenRath is Python.
- License: LLMs-from-scratch is Other, OpenRath is BSD-3-Clause.
- 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.
Choose OpenRath if…
- OpenRath is primarily Python; LLMs-from-scratch is Jupyter Notebook.
- License: OpenRath is BSD-3-Clause, LLMs-from-scratch is Other.
- Tags unique to OpenRath: memory, lllm-agent, llm, model-context-protocol.
- Also covers AI Agents.
When NOT to use OpenRath
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
