My guess is that octopodes are at least up to the bird (parrot) level and perhaps up to the dog/pig level. I don't think they have a large enough brain for primate/dolphin level however.
But you might consider giant squids such as Architeuthis dux or Taningia danae. The can run from 2 to 18 meters in length and weigh up to 900 kg (1,980 lbs). I'd have to believe that they have a relatively large brain as well.
Interestingly enough, these species would be relatively near the top of their food chain and live in fairly safe and unchanging environments and have good defensive systems -- a recipe for allowing genetic programs for very long lifespans.
