Latest news

2024: LLM - Hugging Face - New Horizons

As 2024 began, I embarked on a new chapter of self-discovery and growth, dedicating my free time outside of my role at Snowpack to contributing to open-source projects as a means of continuous learning. One project that particularly captured my interest was llama.cpp, an innovative initiative enabling the deployment of large language models locally, without relying on external servers.

As I began contributing to llama.cpp, I was thrilled to see the project grow and gain momentum. My efforts did not go unnoticed, and I was approached by Julien Chaumond, CTO of Hugging Face, who expressed interest in collaborating with me on on-device LLM technologies such as ggml, ONNX, and more.

I was honored to accept the offer and joined Hugging Face in August 2024. I was eager to leverage this opportunity to expand my knowledge in LLM and AI, and I was not disappointed. Working alongside a talented team, I was immersed in a dynamic and innovative environment that fostered growth and exploration.

One of the highlights of my tenure at Hugging Face was the launch of the Ollama compatibility layer in October 2024. In collaboration with my colleagues, we successfully bridged the gap between two prominent LLM platforms, enabling users to utilize GGUF models from Hugging Face directly on Ollama. In the 24 hours following the release, we received over 20,000 requests from users to download a wide variety of models. This achievement was a testament to the power of collaboration and innovation, and I was proud to have played a part in it.

As I reflect on my time at Hugging Face thus far, I am filled with a sense of accomplishment and gratitude. I am excited to continue contributing to the domain of LLM and AI, and I look forward to the opportunities and challenges that lie ahead.
