Abstract
A short review of some of the most relevant contributions to non-perturbative QED is done. Since a Gaussian behaviour of QED \`a la has been ruled out by the numerical data, I analyse the other two most reliable scenarios, i.e. triviality \`a la Nambu-Jona Lasinio and non-Gaussian critical behaviour. I give a suggestive theoretical argument against a Gaussian behaviour of QED \`a la Nambu-Jona Lasinio, and show how the numerical data for the susceptibility at the critical point of QED support this result.
