Eventually but probably not for many years.

AI will need to be coupled with robotics and bio manufacturing and probably some sort of energy breakthrough before we get massive deflation. While we are still pulling stuff out of the earth to get the materials and minerals we need to make the goods AI can only have so much impact. Even if labour costs went down drastically due to AI replacing jobs governments will be forced to print the difference and hand out money because a fiat debt based system cannot sustain on even a small amount of persistent deflation.
