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, whisper-ctranslate2 is MIT. - 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, LLM Frameworks, Model Training. - 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 whisper-ctranslate2 if… - License: whisper-ctranslate2 is MIT, transformers is Apache-2.0. - Tags unique to whisper-ctranslate2: openai, openai-whisper, speech-to-text, whisper. - Also covers Developer Tools. - whisper-ctranslate2 ships Docker support for self-hosted deployment. ## 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 whisper-ctranslate2 - Last GitHub push was 147 days ago (slowing maintenance, Feb 14, 2026). Validate activity before betting a new project on whisper-ctranslate2. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## Common questions ### What is the difference between transformers and whisper-ctranslate2? transformers: Transformers: the model-definition framework for state-of-the-art machine learning models in text, vision, audio, and multimodal models. whisper-ctranslate2: Whisper command line client compatible with original OpenAI client based on CTranslate2..
