## Choose when

### Choose train-llm-from-scratch if…

- License: train-llm-from-scratch is MIT, Megatron-LM is Other.
- 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 are focused on training large transformer models but `train-llm-from-scratch` is more of a standalone tutorial, whereas NVIDIA’s Megatron-LM scales up the process for massive models.
- Tags unique to train-llm-from-scratch: training, llm, gemini, openai.
- You're interested in building an LLM from the ground up without relying on prebuilt packages like transformers or peft.

### Choose Megatron-LM if…

- License: Megatron-LM is Other, train-llm-from-scratch is MIT.
- Both are focused on training large transformer models but `train-llm-from-scratch` is more of a standalone tutorial, whereas NVIDIA’s Megatron-LM scales up the process for massive models.
- Tags unique to Megatron-LM: model-para.
- - When you are working with large-scale transformer models that require efficient use of GPUs

## 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.

## When NOT to use Megatron-LM

- - If your team is working with small-scale models where the overhead of complex GPU optimizations is not necessary
- - When the research focus does not require or benefit from distributed training, as Megatron-LM's strength lies in its scalable training capabilities
- - For scenarios where minimal code complexity and ease-of-use are more important than customization or fine-tuned performance, considering alternatives might be better
