The Vile Offspring from the book Accelerando.

Vile Offspring: Derogatory term for the posthuman “weakly godlike intelligences” that inhabit the inner Solar System by the novel’s end.

Also Aineko

Aineko, is not a talking cat: it’s a vastly superintelligent AI, coolly calculating, that has worked out that human beings are more easily manipulated if they think they’re dealing with a furry toy. The cat body is a sock puppet wielded by an abusive monster.
