Valve's upcoming MOBA-hero shooter, Deadlock, recently overhauled its matchmaking system, thanks to a surprising source: the AI chatbot ChatGPT. A Valve engineer revealed this innovative approach on Twitter (X).
ChatGPT's Role in Deadlock's Matchmaking Overhaul
Valve engineer Fletcher Dunn shared his experience using ChatGPT to find a suitable algorithm for Deadlock's matchmaking. The AI chatbot recommended the Hungarian algorithm, which the team subsequently implemented. Dunn’s Twitter posts included screenshots of his conversation with ChatGPT, showcasing the AI's helpful role in this process.
Deadlock's previous MMR matchmaking system had faced considerable criticism from players. Reddit threads highlighted complaints about unevenly matched teams, with skilled players often paired against less experienced teammates. Players expressed frustration with the perceived imbalance and the lack of consideration for player experience levels.

The implementation of the Hungarian algorithm, facilitated by ChatGPT, represents a significant step in addressing these issues.
Dunn's reliance on ChatGPT is noteworthy. He highlighted the AI's growing utility, stating that he keeps a dedicated browser tab open for it. He even expressed his intention to continue sharing his successes with ChatGPT, aiming to counter skepticism about the AI's capabilities.
While acknowledging the benefits of speed and efficiency offered by generative AI, Dunn also raised concerns about its potential impact on human interaction. He noted that using ChatGPT often replaces the need to consult with other human developers, either in person or online.
The algorithm's function in a gaming context is to optimize matches, considering player preferences to create balanced and engaging gameplay. Dunn specifically sought an algorithm that prioritized one side's preferences (e.g., a player's preferred teammates), a challenge effectively solved by the Hungarian algorithm's bipartite matching capabilities.
Despite the improvements, some players remain critical of Deadlock's matchmaking, expressing their dissatisfaction on social media. These negative reactions highlight the ongoing challenge of satisfying all players in online gaming, even with advanced algorithmic solutions.
