You will definitely want to use the 0.15.00 Version of Adamant Mod (as of yet unreleased), as it fixes some of the more glaring issues with the AIs (as well as having 74 items in the changelog!

). I am implementing Machine and Energy races, but they are still a ways off from being completed... I can release 0.15.00 in the next day or so for you now, with those race types unavailable of course. Note that all empire files created prior to 0.15.00 will _not_ be usable in 0.15.00.
I am not sure that the AI for Adamant can be classified as "devious" though... It is probably about the same level as stock SE4 AI, albiet rather uniform... If you decide to create some better AIs, I would be more than happy to include them in the mod.
Have you been playing Adamant in single player mode?
Edit:
I have attached the current 0.15.00 history file to this post.
