Abstract
Despite much progress in training AI systems to imitate human language, building agents that use language to communicate intentionally with humans in interactive environments remains a major challenge. We introduce Cicero, the first AI agent to achieve human-level performance in Diplomacy, a strategy game involving both cooperation and competition that emphasizes natural language negotiation and tactical coordination between seven players. Cicero integrates a language model with planning and reinforcement learning algorithms by inferring players' beliefs and intentions from its conversations and generating dialogue in pursuit of its plans. Across 40 games of an anonymous online Diplomacy league, Cicero achieved more than double the average score of the human players and ranked in the top 10% of participants who played more than one game.

I commented back in June 2020 of SBER that "natural language Diplomacy agents surely can't be too much more difficult given NLM progress...", and indeed, they were not, despite the insane leap in capabilities from "the best NN can't even beat humans at a simplified Diplomacy shorn of all communication and negotiation and manipulation and deception aspects" to "NNs can now talk a lot of human players into losing". The tide is rising, and it is still May 2020.
