A non-trivial quantum field theory (QFT) in four dimensions is not in sight. We are working on a programme which formulates QFT on a noncommutative geometry and uses techniques from matrix models to rigorously construct these QFT models. The simplicity of the resulting models permits explicit and exact formulae for correlation functions. In this way we can study positivity properties which eventually decide whether the constructed models define a true quantum field theory.
