Does OSL use GPU on new MacBook Pros?

Disclaimer: I’m pretty new to most of this stuff. But looking through the splash page for Blender 3.5, I see that Blender uses Metal for the viewport on MacOS, and that OSL now supports OptiX GPU communication… But what does this mean for the M1 chip in the new MacBooks? Will OSL communicate with them or continue to use the CPU because it’s not an Nvidia processor?
