thank you

Welcome!

Wouldn't you use a low-ish resistor on the output to test what power the opamp can deliver? Open-output would be almost no current, not high-current test as in the title

[@stemscience1]

Kindly refer to the datasheet of the part explained. You will see how title is correct

@@stemscience1You did not understand their question correctly. The part is theoretically capable of high current output, but *your simulation* is not simulating a high-current load. You have nothing connected to the output, so your simulation is just simulating a high-impedance output, and does not show what the circuit will actually do when attached a low-impedance (high-current) load.
