{"slug": "what-is-weight", "title": "What is weight?", "summary": "Model weights are the adjustable numerical parameters inside a machine learning model that are fine-tuned during training to improve performance, analogous to ingredient amounts in a recipe. Downloading model weights from platforms like Hugging Face provides the learned settings rather than an untrained model.", "body_md": "I think you probably mean **model weights**… :\n\nA simple way to picture it might be a huge recipe.\n\nA model has an enormous number of numerical “amounts” inside it. During [training](https://docs.pytorch.org/tutorials/beginner/basics/optimization_tutorial.html), those amounts are adjusted little by little depending on how well the model is doing. Those adjustable numbers are its **parameters**, and many of them are **weights**.\n\nSo when you see something like “[download/load the model weights](https://huggingface.co/docs/transformers/models)” on Hugging Face, it basically means getting those learned numerical settings instead of starting with an untrained model.", "url": "https://wpnews.pro/news/what-is-weight", "canonical_source": "https://discuss.huggingface.co/t/what-is-weight/179676#post_2", "published_at": "2026-09-01 21:14:29+00:00", "updated_at": "2026-09-01 21:24:52.346105+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": ["Hugging Face", "PyTorch"], "alternates": {"html": "https://wpnews.pro/news/what-is-weight", "markdown": "https://wpnews.pro/news/what-is-weight.md", "text": "https://wpnews.pro/news/what-is-weight.txt", "jsonld": "https://wpnews.pro/news/what-is-weight.jsonld"}}
