The critical amplitude A0 of the free energy density of the Baxter model is studied numerically on strips with widths L=2-12 as a function of the four-spin interaction K4. It remains almost constant, near to double the exactly known Ising result (A0=2A0Ising= pi /6) in the range of K4 values for which an extrapolation to infinite width is possible.
