Choose LlamaFactory if…
- License: LlamaFactory is Apache-2.0, mergoo is LGPL-3.0.
- Tags unique to LlamaFactory: gemma, deepseek, ai, instruction-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 mergoo if…
- License: mergoo is LGPL-3.0, LlamaFactory is Apache-2.0.
- Tags unique to mergoo: merge, lora, llm, artificial-intelligence.
- Leaner open-issue backlog (11).
When NOT to use mergoo
- Last GitHub push was 685 days ago (dormant maintenance, Aug 26, 2024). Validate activity before betting a new project on mergoo.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
