At CEDEC 2016 in Japan, Square Enix hosted a panel (livestreamed on Nico Nico) showcasing the advanced AI systems used in Final Fantasy XV. 

The panel featured several clips showcasing characters and monsters in action, and you can check them out below.

Please keep in mind that all the videos below are recorded from Nico Nico, so the quality is quite bad, especially since they were showcased in a smaller window of an already low-resolution screen.

To kick things off, a trailer featuring the whole spectrum of the AI systems used in the game was showcased. And yes, Prompto sings the classic Final Fantasy victory fanfare while attacking.

Secondly, we get a few clips showcasing party AI, gathered in the video below. The first clip shows party characters avoiding Noctis, compared with the same situation with the feature turned off.

The second clip shows how the AI will select the best candidate to heal Noctis, compared with the same circumstances with the feature disabled, causing all party members to crowd the protagonist to heal him. In the third clip, the same feature sends Gladio to rescue Noctis.

The fourth clip shows how the dialogue changes from an easy battle to one in which the situation is more dire.

In the fifth clip, characters will turn their head depending on the position of the one they're talking to, both while stationary and in motion.

Last, but not least, in the sixth clip, the AI will behave differently when it's cold or when it rains.

The following video features the "Face 2 Face" system, showcasing dialogue options triggered in real time in various situations, also responding dynamically to the envrionment to reach the target of the conversation.

The clips below showcase the different AI modes: normal mode, lead mode, route mode and follow mode.

In the following video you can see examples of AI for the player character. The first and the second clips are a comparisons between what happens when the AI system that reacts to rain is on or off.

The third clip shows how the character is conscious of his surrounding, and adapts to dialogue even while in motion. The fourth video shows how the set route changes depending on user input.

In the video below we can see Ignis' "mark" player command in action. It's one of the player commands available in the game, and allows us to order Ignis to mark our enemies.

The last video showcases monster AI.

As a funny note of color, the audience was forbidden to film or post on social media one of the clips (you can see the slide below), and it was also removed from the livestream. It showcased the monster AI during pre-production, when things were still very early in development.. Evidently Square Enix did not want to show it publicly, as it isn't representative of the game anymore.
