It supports PyTorch 2.4+ and Python 3 - **License detail:** Transformers is distributed under the Apache-2.0 license, ensuring wide permissions for use in both open-source and proprietary systems. ## Choose when ### Choose transformers if… - Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+. - Tags unique to transformers: audio, deep-learning, machine-learning, natural-language-processing. - Also covers Inference & Serving, Speech & Audio. - The library excels in scenarios where you need highly optimized and pre-trained models available for a wide range of data types including text, vision, audio, and multimodal inputs. ### Choose hallucination-index if… - Tags unique to hallucination-index: hallucinations, large-language-models, llm, llm-evaluation. - Leaner open-issue backlog (1). ## When NOT to use transformers - If the specific task or dataset size does not benefit from state-of-the-art models due to computational inefficiency or overfitting, alternatives may be more suitable. - It might not be the best choice for projects that strictly require compatibility with frameworks other than PyTorch and Python versions older than 3.10. ## When NOT to use 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. ## Common questions ### What is the difference between transformers and hallucination-index? transformers: Transformers: the model-definition framework for state-of-the-art machine learning models in text, vision, audio, and multimodal models. 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 transformers over hallucination-index?

Stars measure visibility, not whether either tool fits your constraints. ### Are transformers and hallucination-index open source? Yes - both are open-source projects on GitHub. ### Where can I find alternatives to transformers or hallucination-index? GraphCanon lists graph-backed alternatives at [transformers alternatives](/tools/huggingface-transformers/alternatives) and [hallucination-index alternatives](/tools/rungalileo-hallucination-index/alternatives) ([transformers markdown twin](/tools/huggingface-transformers/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/huggingface-transformers-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, transformers or hallucination-index? transformers: 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 transformers and hallucination-index? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [transformers trust report](/tools/huggingface-transformers/trust); [hallucination-index trust report](/tools/rungalileo-hallucination-index/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=huggingface-transformers`](/api/graphcanon/graph?tool=huggingface-transformers) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
