The AI will be able to use them as well as other spells it uses - randomly. Keep in mind we are greatly going to increase the strength a summoner brings to the table. As such, we are also going to boost the "AI priorities" so that the AI value them higher. We will put higher priorities on strong summons.
The AI will never be able to analyze and optimize each summon's efficiency. It will not be able to match what you summon with its own summons to exploit your weakness. But it will summon a variety of units based on their overall strength and the AI's own dedication to the summoning method.
