At Hugging Face, we’re on a journey to democratize good AI. We are building the fastest growing platform for AI builders with over 5 million users & 100k organizations who collectively shared over 1M models, 300k datasets & 300k apps. Our open-source libraries have more than 400k+ stars on Github.

About the Role

Post-training is an exciting and fast-moving field of research that is used to enhance the performance of large language models and enable them to follow human instructions. The post-training team at Hugging Face is pushing the frontier of model capabilities by developing recipes [1] that produce state-of-the-art models like Zephyr [2] and NuminaMath [3], which won the 1st Progress Prize of the AI Math Olympiad.

During this internship, you will work alongside the post-training team to implement cutting-edge research and make it accessible to the global AI community in the form of code, datasets, and models. Topics include training LLMs how to reason via test-time compute and how to navigate complex environments that require agentic behaviour. You will have access to a state-of-the-art training codebase, a large research cluster of H100s, and domain experts in Hugging Face's science team.

If you enjoy training LLMs and working across the whole deep learning stack, we’d love to hear from you!
