Typed relationship

train-llm-from-scratch alternative reasoning-from-scratchBoth repositories focus on training large language models from scratch, with similar goals and approaches to building reasoning LLMs.

Choose train-llm-from-scratch if…

  • train-llm-from-scratch is primarily Python; reasoning-from-scratch is Jupyter Notebook.
  • License: train-llm-from-scratch is MIT, reasoning-from-scratch is Apache-2.0.
  • Pricing: This repository is available under the MIT license, allowing free use for both personal and commercial purposes. The model training requires resources on your end with no additional licensing costs..
  • Requirements: A single GPU environment is necessary.; Basic understanding of PyTorch is recommended to leverage the full potential of this tool.; Familiarity with NLP and transformer-based models can be helpful but not mandatory..
  • Both repositories focus on training large language models from scratch, with similar goals and approaches to building reasoning LLMs.
  • Tags unique to train-llm-from-scratch: gemini, llm, openai, transformers.
  • Also covers Inference & Serving.
  • You're interested in building an LLM from the ground up without relying on prebuilt packages like transformers or peft.

When NOT to use train-llm-from-scratch

  • Your goal is to rapidly prototype and fine-tune an existing pre-trained LLM with minimal coding effort.
  • You prefer using established transformer libraries or frameworks like Hugging Face's transformers, which offer quicker setup but less control over the underlying code.
  • You are working in a multi-GPU environment and need distributed training capabilities that go beyond what is offered here.
  • You seek immediate access to state-of-the-art models without wanting to dive into the intricate workings of an LLM.

Choose reasoning-from-scratch if…

  • reasoning-from-scratch is primarily Jupyter Notebook; train-llm-from-scratch is Python.
  • License: reasoning-from-scratch is Apache-2.0, train-llm-from-scratch is MIT.
  • Requirements: Automatic GPU utilization where available, though not strictly necessary for the early chapters..
  • Both repositories focus on training large language models from scratch, with similar goals and approaches to building reasoning LLMs.
  • Tags unique to reasoning-from-scratch: ai, artificial-intelligence, chain-of-thought, deep-learning.
  • Also covers LLM Frameworks.
  • When you have intermediate knowledge of PyTorch and want detailed insights into the implementation process of reasoning LLMS.

When NOT to use reasoning-from-scratch

  • Avoid this tool if you are looking for rapid prototyping or quick model deployment; it focuses more on understanding and building the LLM from scratch rather than providing prebuilt components.
  • If specialized server hardware is available and preferred for the entire project, as chapters 5 and 6 recommend GPU use but earlier sections can be completed with just a CPU.
