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 SimpleTuner if… - License: SimpleTuner is AGPL-3.0, transformers is Apache-2.0. - Tags unique to SimpleTuner: flux-dev, fine-tuning, stable-diffusion, diffusion-models. - Leaner open-issue backlog (21). ### Choose transformers if… - License: transformers is Apache-2.0, SimpleTuner is AGPL-3.0. - Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+. - Tags unique to transformers: pretrained models, deep-learning, natural-language-processing, audio. - Also covers LLM Frameworks, Model Training, Inference & Serving. - 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. ## 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. ## Common questions ### What is the difference between SimpleTuner and transformers? SimpleTuner: A general fine-tuning kit geared toward image/video/audio diffusion models.. transformers: Transformers: the model-definition framework for state-of-the-art machine learning models in text, vision, audio, and multimodal models. See the comparison table for live GitHub stats and shared categories. ### When should I choose SimpleTuner over transformers? Choose SimpleTuner over transformers when License: SimpleTuner is AGPL-3.0, transformers is Apache-2.0; Tags unique to SimpleTuner: flux-dev, fine-tuning, stable-diffusion, diffusion-models; Leaner open-issue backlog (21). ### When should I choose transformers over SimpleTuner? Choose transformers over SimpleTuner when License: transformers is Apache-2.0, SimpleTuner is AGPL-3.0; Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+; Tags unique to transformers: pretrained models, deep-learning, natural-language-processing, audio; Also covers LLM Frameworks, Model Training, Inference & Serving; 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. ### When should I avoid 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. ### Is SimpleTuner or transformers more popular on GitHub? transformers has more GitHub stars (162,482 vs 2,878). Stars measure visibility, not whether either tool fits your constraints. ### Are SimpleTuner and transformers open source? Yes - both are open-source projects on GitHub (SimpleTuner: AGPL-3.0, transformers: Apache-2.0). ### Where can I find alternatives to SimpleTuner or transformers? GraphCanon lists graph-backed alternatives at [SimpleTuner alternatives](/tools/bghira-simpletuner/alternatives) and [transformers alternatives](/tools/huggingface-transformers/alternatives) ([SimpleTuner markdown twin](/tools/bghira-simpletuner/alternatives.md), [transformers markdown twin](/tools/huggingface-transformers/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/bghira-simpletuner-vs-huggingface-transformers.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, SimpleTuner or transformers? SimpleTuner: Very active. transformers: Very active. 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 SimpleTuner and transformers?
