Huggingface is a popular platform for natural language processing (NLP) tasks. It offers a wide range of pre-trained models that can be easily downloaded and used for various applications.
To download pre-trained models from the Huggingface website, you can use the transformers library, which is a Python library developed by Huggingface. This library allows you to easily download and load pre-trained models.
The Huggingface website has a vast collection of pre-trained models that can be browsed and downloaded. You can search for models by name, model type, or task, and download them with a simple click.
The pre-trained models on Huggingface are trained on massive datasets and can achieve state-of-the-art results on various NLP tasks.

Getting Started
To get started, you'll need to install the Hugging Face Transformers Library, which allows you to download and use pre-trained models.
The library can be installed using a one-line installer that works on Linux, Mac, and Windows WSL2.
This script downloads the correct version based on your OS and architecture and saves the binary as "hfdownloader" in the current folder.
If required, it will automatically request higher 'sudo' privileges, so be prepared to grant access if prompted.
You can specify the install destination with the -p option if you want to install the library somewhere other than the default location.
Install Libraries:
To install the necessary libraries, you'll need to start by installing the HuggingFace libraries. This can be done by running a command in your terminal or command prompt.
The command to install the core Hugging Face library along with its dependencies is straightforward. It's: "Open a terminal or command prompt and run the following command..."
Installing the datasets and tokenizers library is also a good idea for full capability. This will give you access to a wider range of features and functionality.
The Transformers library is a crucial part of the Hugging Face ecosystem, and it's the first library you should install. This library allows you to download and use pre-trained models.
Using Pre-Trained Models
Using pre-trained models is a game-changer for developers, as it allows them to leverage the power of state-of-the-art models without having to train them from scratch. These models have already been trained on large datasets and are optimized for specific tasks, saving both time and computational resources.
Hugging Face has two main libraries that provide access to pre-trained models: Transformers and Diffusers. The Transformers library handles text-based tasks, such as translation, summarization, and text generation.
To find the right pre-trained model, you can browse the models on the Hugging Face website, filter them by task, language, framework, and more, or search for models and datasets by keyword. Each model has a model card that contains important information, such as model details, inference example, training procedure, community interaction features, and a link to the files.
You can also check the list of spaces that are using that particular model and further explore the spaces by clicking on the space link.

Use Pre-Trained
Using Pre-Trained Models is a game-changer for developers, as it allows you to leverage the power of state-of-the-art models without having to train them from scratch. These models have already been trained on large datasets and are optimized for specific tasks, saving both time and computational resources.
Hugging Face models are highly customizable and can be fine-tuned for specific tasks, making them incredibly versatile. You can use the Transformers library to handle text-based tasks, such as translation, summarization, and text generation, while the Diffusers library can handle image-based tasks, like image synthesis, image editing, and image captioning.
To find the right pre-trained model, you can browse the models on the Hugging Face website and filter them by task, language, framework, and more. You can also search for models and datasets by keyword and sort them by trending, most likes, most downloads, or by recent updates.
Some popular pre-trained models include the T0_3B model, which is a large-scale language model that can be used for text generation and translation. You can download this model and its tokenizer using the AutoTokenizer and AutoModelForSeq2SeqLM classes from the transformers library.

Here are the steps to download and manage your models:
- Download the Model and Tokenizer: Use the AutoTokenizer and AutoModelForSeq2SeqLM classes to download your model and tokenizer.
- Save the Model and Tokenizer Locally: After downloading, save the files to a specified directory.
- Load the Model and Tokenizer Offline: When you are offline, you can load your model and tokenizer from the local directory.
You can also use the WebUI to download Hugging Face models, but this requires placing them in a specific directory on your computer.
Deep Link
Deep Link is a feature in Jan Hub that allows you to download specific models from Hugging Face with a single click. This is a game-changer for anyone who uses pre-trained models regularly.
To use the deep link feature, you'll need to know the model's ID. You can find this by going to the Hugging Face website, selecting the desired model, and copying the Model's ID or URL. For example, TheBloke/Magicoder-S-DS-6.7B-GGUF.
Once you have the model's ID, you can enter the deep link URL in your browser, formatted as jan://models/huggingface/TheBloke/Magicoder-S-DS-6.7B-GGUF. This will launch the Jan app and show you all available versions of the model.
To download the model, simply click Download. That's it! You'll have the model downloaded in no time.
Note that the deep link feature is not available for models that require an API Token or acceptance of a usage agreement. These models must be downloaded manually.

Finding and Using Models
You can find the right pre-trained model on the Hugging Face website by browsing and filtering models by task, language, framework, and more. You can also search for models and datasets by keyword and sort them by trending, most likes, most downloads, or by recent updates.
Each model has a model card that contains important information, such as model details, inference example, training procedure, community interaction features, and link to the files. You can try the model on the model card page by using the Inference API section.
To download a model, you can use the WebUI by navigating to the Model tab, entering the model's Hugging Face ID, and clicking Download. Alternatively, you can use the PreTrainedModel.from_pretrained and PreTrainedModel.save_pretrained methods to download and save the model locally.
Here are the steps to download a model using the PreTrainedModel methods:
- Download the Model and Tokenizer: Use the following code to download your model and tokenizer: `tokenizer = AutoTokenizer.from_pretrained("bigscience/T0_3B") model = AutoModelForSeq2SeqLM.from_pretrained("bigscience/T0_3B")`
- Save the Model and Tokenizer Locally: After downloading, save the files to a specified directory: `tokenizer.save_pretrained("./your/path/bigscience_t0") model.save_pretrained("./your/path/bigscience_t0")`
- Load the Model and Tokenizer Offline: When you are offline, you can load your model and tokenizer from the local directory: `tokenizer = AutoTokenizer.from_pretrained("./your/path/bigscience_t0") model = AutoModelForSeq2SeqLM.from_pretrained("./your/path/bigscience_t0")`
You can also download models directly from the Model Hub by clicking the download icon next to the model you wish to use.
