Choose Megatron-LM if…
- License: Megatron-LM is Other, torchtitan is BSD-3-Clause.
- Requirements: Min 32 GB RAM; Requires NVIDIA GPUs for optimized performance. Non-GPU usage is not supported or recommended.; Installation from source can be resource-intensive and may require limiting parallel compilation jobs to avoid running out of memory..
- Tags unique to Megatron-LM: large language models, model-para, transformers.
- The tool is particularly beneficial when your project is GPU-centric and benefits from advanced parallelism techniques such as Tensor, Pipeline, Data, Expert, and Cluster Parallelisms (TP, PP, DP, EP,
When NOT to use Megatron-LM
- Avoid Megatron-LM if your computational setup does not include NVIDIA GPUs as it leverages GPU-specific features and parallelisms that may not be available or efficient on non-NVIDIA hardware.
- If you need portability across various hardware without depending on proprietary optimizations, other tools might better serve your needs.
Choose torchtitan if…
- License: torchtitan is BSD-3-Clause, Megatron-LM is Other.
- Requirements: Facilitates training processes for generative AI models using PyTorch..
- Tags unique to torchtitan: generative models, pytorch, training platform.

When NOT to use torchtitan
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
