Choose trainer if…
- trainer is primarily Go; litgpt is Python.
- Requirements: Min 8 GB RAM.
- Tags unique to trainer: distributed, fine-tuning, gpu, huggingface.
- You need to fine-tune large language models or orchestrate complex training workflows across multiple nodes on a Kubernetes cluster.
When NOT to use trainer
- If your setup does not have a Kubernetes environment configured, as this could require significant changes in infrastructure to start using trainer efficiently.
- When you plan to implement your model training within another container orchestration system, such as Docker Swarm or Amazon ECS, since Trainer is optimized for operation with Kubernetes.
Choose litgpt if…
- litgpt is primarily Python; trainer is Go.
- Pricing: The core LitGPT framework is free to use under an open source license, but users might encounter costs when deploying at scale or using high-performance models..
- Requirements: Min 16 GB RAM.
- Tags unique to litgpt: artificial-intelligence, deep-learning, large language models, llm-inference.
- Also covers Inference & Serving.
- If you are focusing on a project that requires rapid prototyping or experimentation with over 20 different LLMs to find the best fit for your application.
When NOT to use litgpt
- If you need a tool specifically optimized for resource-constrained devices, as LitGPT focuses on high-performance LLMs and may require more resources.
- When your project is strictly limited to only one or two types of specific LLMs; in this case, another specialized framework that caters narrowly might be preferable.
