It had:

  • An AI that got its own planet
  • An interplanetary train system, with portals on every planet
  • An elf-like species that could travel through weird portals called "the paths" or something like it
  • no ships, towards the end of the story
  • an invader species that has smart immobile units and dumber mobile units
  • the artificial intelligence made "restricted intelligence" as a gift to humans
  • A nova bomb is made and used towards the end
  • People have many implants that make them better at things

Does anyone know the title and author of the book?

    The train bit along with the implants immediately makes me thing of Peter F Hamilton's Commonwealth Saga, but I haven't read most of the series and the plot points aren't ringing any bells. – Harabeck Dec 13 '19 at 21:25

    (Wow, the new automatic text for dupe closures looks weird and almost confrontational and doesn't really suggest that you're just notifying of a duplicate) – starpilotsix Dec 14 '19 at 1:17

The is Pandora's Star and Judas Unchained, the first and second halves of a 2000-page novel by Peter Hamilton set in his Commonwealth saga. It's a match to your specs in every respect.

    Isn't Pandora's Star the first and Judas Unchained the second? – user22484 Dec 14 '19 at 7:02
  • @user22484 Yes. You can edit the answer. – Faheem Mitha Dec 14 '19 at 7:33
