Omar Sanseviero

Hi there! I’m Omar, the Chief Llama Officer at Hugging Face. πŸ¦™

I work at the intersection of Open Source, Product, Research, and technical communities, leading multidisciplinary teams and open source and science collaborations.

Previously, I was a Software Engineer at Google building ML models and infrastructure that power multiple features in Google Assistant. I also had a short stint as a 20% Product Manager in the TensorFlow Graphics team.

In this website, I write about Machine Learning and Open Source. πŸ€— Check out the Blog section!

About my work at Hugging Face

One of the funnest things about my role is that no day looks the same. One day might be a rush to get Llama 2 ready for releasing, while another day might involve learning and writing about Mixture of Experts. Given my role, I get to work with a bunch of folks all across the company and ecosystem, from research to product. I try to do most of my work in the open, so you can check my social media accounts or GitHub to see some of my work. Some of the things I’m proud to have shipped:

  • We launched Hugging Face Spaces at the end of 2022; it enables the community to build, share, and collaborate in ML demos. With consistent growth for 2 years, we went from 500 Spaces to over 400k demos built by the community!
  • Created and grew up the Developer Advocacy Engineering and Moonshot teams; the teams work in ML topics such as on-device, Audio, Healthcare, Artists Ecosystems, Reinforcement Learning, 3D Computer Vision, Gaming, and more!
  • Built key collaborations and partnerships with OS communities and libraries.
  • Implemented technical integrations with OS libraries such as spaCy and Sentence Transformers.
