Ask a teammate for help in PUBG and the game keeps moving while they decide what you mean. The team behind PUBG Ally describes an AI partner built to handle that difference in speed. A language model interprets speech, keeps track of context and chooses actions at a high level. A faster controller carries out movement, combat and recovery.
The language model receives game information through a controlled interface. It can act on information it gets from the game and from the player, while its decisions steer the controller. The authors say this interaction also shapes what training data they need. A line of dialogue can change how the match unfolds, so they trained with examples drawn from actual gameplay.
This is the developers' account of the system. The architecture gives players a concrete reason a partner can react quickly to combat while taking longer to answer a question.
