Field-level inference has emerged as a powerful tool for extracting maximal information from cosmic fields, enabling the constraints on physics and inference of the early universe's initial conditions. In this colloquium, I will present my pioneering application of field-level inference to infer the physics of the primordial universe, explicitly focusing on primordial non-Gaussianity. My method offers the potential to address several open challenges in this field, such as effectively handling observational effects and breaking degeneracies within the physics model. Additionally, I will touch upon other relevant applications, including weak lensing at the field level and ongoing reconstructions. Finally, I will provide an exciting outlook on future projects that field-level inference can unlock, expanding our possibilities in the field of cosmology and beyond.
