Hugging Face
Hugging Face, Inc. is a French-American company and open-source community that develops tools and resources  to build, deploy, and train  machine learning models. Based in New York City, the company is most notable for its Transformers library built for natural language processing and emphasis on community collaboration and accessibility. Its platform allows users to share machine learning models and datasets and showcase their work. History 
The company was founded in 2016 by French entrepreneurs Clément Delangue, Julien Chaumond, and Thomas Wolf in New York City, originally as a company that developed a chatbot app targeted at teenagers. After open-sourcing the model behind the chatbot, the company pivoted to focus on being a platform for machine learning. In March 2021, Hugging Face raised US$40 million in a Series B funding round. On April 28, 2021, the company launched the BigScience Research Workshop in collaboration with several other research groups to release an open large language model. In 2022, the workshop concluded with the announcement of BLOOM, a multilingual large language model with 176 billion parameters. On December 21, 2021, the company announced its acquisition of Gradio, a software library used to make interactive browser demos of machine learning models. On May 5, 2022, the company announced its Series C funding round led by Coatue and Sequoia. The company received a $2 billion valuation. On May 13, 2022, the company introduced its Student Ambassador Program to help fulfill its mission to teach machine learning to 5 million people by 2023. On May 26, 2022, the company announced a partnership with Graphcore to optimize its Transformers library for the Graphcore IPU. On August 3, 2022, the company announced the Private Hub, an enterprise version of its public Hugging Face Hub that supports SaaS or on-premises deployment. In February 2023, the company announced partnership with Amazon Web Services (AWS) which would allow Hugging Face's products available to AWS customers to use them as the building blocks for their custom applications. The company also said the next generation of BLOOM will be run on Trainium, a proprietary machine learning chip created by AWS. In August 2023, the company announced that it raised $235 million in a Series D funding, at a $4.5 billion valuation. The funding was led by Salesforce,  and notable participation came from Google, Amazon, Nvidia, AMD, Intel, IBM, and Qualcomm. Services and technologies

Transformers Library 
The Transformers library is a Python package that contains open-source implementations of transformer models for text, image, and audio tasks. It is compatible with the PyTorch, TensorFlow and JAX deep learning libraries and includes implementations of notable models like BERT and GPT-2. The library was originally called "pytorch-pretrained-bert" which was then renamed to "pytorch-transformers" and finally "transformers." Hugging Face Hub 
The Hugging Face Hub is a platform (centralized web service) for hosting:

 Git-based code repositories, including discussions and pull requests for projects. models, also with Git-based version control;
 datasets, mainly in text, images, and audio;
 web applications ("spaces" and "widgets"), intended for small-scale demos of machine learning applications. Other libraries 
In addition to Transformers and the Hugging Face Hub, the Hugging Face ecosystem contains libraries for other tasks, such as dataset processing ("Datasets"), model evaluation ("Evaluate"), simulation ("Simulate"), machine learning demos ("Gradio"). References
