Decision brief

litgpt offers a suite of over 20 high-performance large language models, with tools for pretraining, finetuning, and deployment at scale, all under the Apache-2.0 license.

Good fit when

  • When you need a comprehensive set of over 20 high-performance LLMs for pretraining, finetuning, and deployment.
  • If you are working with Python and prefer a framework that supports large-scale deployment of LLMs.

Avoid when

  • 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.
