That's about the limit of my recommendations myself. I loved Revelation Space and enjoyed the others in the series but found that the more I checked out Reynolds beyond that series, the more hit and miss he got. It's been years since I finished a new fiction book.

Stone by Adam Roberts is an odd story that hints at an AI element as it goes on. Dreaming in Smoke by Tricia Sullivan is a bit 90s-woman-pretentious (a heroine called 'Kalypso Deed' who loves jazz - nuff said) but has some themes of communicating with a greater alien intelligence. I enjoyed both but read them absolutely yonks ago in my teens, when I was much less critical, so I can't promise either one is a recommendation that stands the test of time. Neither's really about the god-like sprawling entities that Vinge plays with, either.

Someone else here mentioned Blindsight by Peter Watts and I know that deals with post-singularity consciousness somehow, but I haven't read it.

EDIT - oh I forgot The Metamorphosis of Prime Intellect, as a classic depiction of a doomsday strong AI awakening scenario. Read it online many years ago so it inhabits a different part of my mind to paper novels. Some edgy degenerate shit in it on reflection, plus the ending was absurd to me, but it's a well known, well done technological singularity idea if you haven't already read it.

Way back in the mists of time I also started and never finished Lady of Mazes by Karl Schroeder, because I lost the book. I think I was drawn to it by some sci fi AI elements, but not having ever finished it, I can't say if my instincts were right.
