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 custom-diffusion if… - License: custom-diffusion is Other, transformers is Apache-2.0. - Tags unique to custom-diffusion: text-to-image-generation, customization, fine-tuning, few-shot. - Leaner open-issue backlog (52). ### Choose transformers if… - License: transformers is Apache-2.0, custom-diffusion is Other. - Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+. - Tags unique to transformers: pretrained models, deep-learning, machine-learning, natural-language-processing. - Also covers LLM Frameworks, 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. ## When NOT to use custom-diffusion - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## 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 custom-diffusion and transformers? custom-diffusion: Custom Diffusion: Multi-Concept Customization of Text-to-Image Diffusion (CVPR 2023). 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 custom-diffusion over transformers? Choose custom-diffusion over transformers when License: custom-diffusion is Other, transformers is Apache-2.0; Tags unique to custom-diffusion: text-to-image-generation, customization, fine-tuning, few-shot; Leaner open-issue backlog (52). ### When should I choose transformers over custom-diffusion? Choose transformers over custom-diffusion when License: transformers is Apache-2.0, custom-diffusion is Other; Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+; Tags unique to transformers: pretrained models, deep-learning, machine-learning, natural-language-processing; Also covers LLM Frameworks, 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. ### When should I avoid custom-diffusion? Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### 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 custom-diffusion or transformers more popular on GitHub? transformers has more GitHub stars (162,482 vs 1,975). Stars measure visibility, not whether either tool fits your constraints. ### Are custom-diffusion and transformers open source? Yes - both are open-source projects on GitHub (custom-diffusion: Other, transformers: Apache-2.0). ### Where can I find alternatives to custom-diffusion or transformers? GraphCanon lists graph-backed alternatives at [custom-diffusion alternatives](/tools/adobe-research-custom-diffusion/alternatives) and [transformers alternatives](/tools/huggingface-transformers/alternatives) ([custom-diffusion markdown twin](/tools/adobe-research-custom-diffusion/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/adobe-research-custom-diffusion-vs-huggingface-transformers.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, custom-diffusion or transformers? custom-diffusion: Steady. 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 custom-diffusion and transformers? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [custom-diffusion trust report](/tools/adobe-research-custom-diffusion/trust); [transformers trust report](/tools/huggingface-transformers/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=adobe-research-custom-diffusion`](/api/graphcanon/graph?tool=adobe-research-custom-diffusion) - 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/_
