Spontaneous creation of radiation?

In (cold) inflation, the rapid exponential expansion of the universe quickly reduces the density of any matter or radiation present to a negligible amount. How is that radiation replaced or supplemented within the warm inflation model? Are you creating something from nothing? Or from fluctuations in the inflaton field?
