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… - License: transformers is Apache-2.0, Confucius4-TTS is Other. - Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+. - Tags unique to transformers: pretrained models, machine-learning, natural-language-processing, speech-recognition. - Also covers LLM Frameworks, Inference & Serving, Computer Vision. - 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 Confucius4-TTS if… - License: Confucius4-TTS is Other, transformers is Apache-2.0. - Tags unique to Confucius4-TTS: multi-lingual, fine-tuning, cross-lingual, speech-synthesis. - Leaner open-issue backlog (10). ## 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 Confucius4-TTS - 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 Confucius4-TTS? transformers: Transformers: the model-definition framework for state-of-the-art machine learning models in text, vision, audio, and multimodal models. Confucius4-TTS: Confucius4-TTS: a Multilingual and Cross-Lingual Zero-Shot TTS Engine. See the comparison table for live GitHub stats and shared categories. ### When should I choose transformers over Confucius4-TTS? Choose transformers over Confucius4-TTS when License: transformers is Apache-2.0, Confucius4-TTS is Other; Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+; Tags unique to transformers: pretrained models, machine-learning, natural-language-processing, speech-recognition; Also covers LLM Frameworks, Inference & Serving, Computer Vision; 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 choose Confucius4-TTS over transformers?
