Choose litgpt if…
- Tags unique to litgpt: large-language-models, llm, llm-inference, llms.
- Also covers LLM Frameworks.
- When you need a comprehensive set of over 20 high-performance LLMs for pretraining, finetuning, and deployment.
When NOT to use litgpt
- If you are looking for a tool that supports languages other than Python, as litgpt is exclusively Python-based.
- When you need a tool that offers fewer model options, as litgpt provides over 20 models which might be overwhelming for specific use cases.
- If you require proprietary licensing, as litgpt is open-source under the Apache-2.0 license.
Choose pytorch-lightning if…
- Tags unique to pytorch-lightning: data-science, machine-learning, python, pytorch.
- Scalable ML model training with consistent API across single to multiple GPUs
- More GitHub stars (31k vs 14k) - visibility, not fit.
When NOT to use pytorch-lightning
- For lightweight models requiring minimal configuration or manual control over model distribution
- Projects that target environments without access to multi-GPU setups and do not require scalability features
