How to get free GPU for machine learning?

I'm curious to know, is there really a way to acquire free GPU resources for machine learning? I've been exploring various options to expand my computational capabilities but the costs associated with purchasing high-end GPUs are quite prohibitive. Are there any platforms or programs that offer free GPU access for researchers or enthusiasts in the field of machine learning? Additionally, if such resources exist, what are the eligibility criteria and how competitive is the process to acquire them? I'm keen to learn more about the feasibility of utilizing free GPU for my machine learning projects.
