Trust report

Choose LlamaFactory if…

  • License: LlamaFactory is Apache-2.0, rellm is MIT.
  • Tags unique to LlamaFactory: agent, ai, deepseek, fine-tuning.
  • When you need to fine-tune over 100 different LLMs or VLMs with efficient methods like LoRA or QLoRA.

When NOT to use LlamaFactory

  • When you are looking to fine-tune less popular or niche models that are not supported within the 100+ models covered by LlamaFactory.
  • If your project specifically requires custom fine-tuning methods not available in this repository, such as certain versions of PEFT (Parameter Efficient Fine-Tuning) techniques excluding LoRA and QLoa

Choose rellm if…

  • License: rellm is MIT, LlamaFactory is Apache-2.0.
  • Tags unique to rellm: huggingface-transformers, llm, transformers.
  • - When you require precise and exact structure in output data generated from any language model, utilizing rellm can ensure consistency.

When NOT to use rellm

  • - Avoid using rellm if you are not working with the Hugging Face Transformers library or do not need structured output formats.
  • - If your project can tolerate some level of unstructured or less rigidly formatted outputs from language models, other solutions might be more appropriate.
