Validate activity before betting a new project on hallucination-index. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## Common questions ### What is the difference between LlamaFactory and hallucination-index? LlamaFactory: Unified Efficient Fine-Tuning of 100+ LLMs & VLMs. hallucination-index: Initiative to evaluate and rank the most popular LLMs across common task types based on their propensity to hallucinate.. See the comparison table for live GitHub stats and shared categories. ### When should I choose LlamaFactory over hallucination-index? Choose LlamaFactory over hallucination-index when 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; More GitHub stars (73k vs 116) - visibility, not fit. ### When should I choose hallucination-index over LlamaFactory? Choose hallucination-index over LlamaFactory when Tags unique to hallucination-index: hallucinations, llm, llm-evaluation, openai; Also covers Computer Vision; Leaner open-issue backlog (1). ### When should I avoid 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 ### When should I avoid hallucination-index? Last GitHub push was 348 days ago (slowing maintenance, Jul 28, 2025). Validate activity before betting a new project on hallucination-index. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### Is LlamaFactory or hallucination-index more popular on GitHub? LlamaFactory has more GitHub stars (73,157 vs 116). Stars measure visibility, not whether either tool fits your constraints. ### Are LlamaFactory and hallucination-index open source? Yes - both are open-source projects on GitHub. ### Where can I find alternatives to LlamaFactory or hallucination-index? GraphCanon lists graph-backed alternatives at [LlamaFactory alternatives](/tools/hiyouga-llamafactory/alternatives) and [hallucination-index alternatives](/tools/rungalileo-hallucination-index/alternatives) ([LlamaFactory markdown twin](/tools/hiyouga-llamafactory/alternatives.md), [hallucination-index markdown twin](/tools/rungalileo-hallucination-index/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/hiyouga-llamafactory-vs-rungalileo-hallucination-index.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, LlamaFactory or hallucination-index? LlamaFactory: Very active. hallucination-index: Slowing. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for LlamaFactory and hallucination-index?
