Abstract
We summarize and discuss various constraints on the IMF at very low or zero metallicity. Taken together the indications from stars, high-z galaxies, and indirect constraints show some possible deviations (favoring massive stars) from a Salpeter like IMF. However, the empirical evidence remains presently arguably weak.
