Valve is one of the many game developers that use generative AI effectively behind the scenes for many great titles. And now, Valve has used this amazing tool, ChatGPT, for matchmaking in the Valve Deadlock Game as admitted by Fletcher Dunn in a recent X post.
This is not surprising as a year-old survey found that 31% of game developers use generative AI in some way. It’s extremely likely that this percentage has definitely increased since then, as more developers are getting exposed to it and AI has evolved and become more prominent.
Fletcher Dunn Admits Using ChatGPT in Deadlock’s Matchmaking
An engineer who has been working with Valve for over a decade, Fletcher Dunn, admitted having used ChatGPT for the current matchmaking in the Valve Deadlock Game. He has been posting about his “ChatGPT wins” on X, saying that OpenAI’s large language model is an “amazing” tool. From the looks of it, Dunn is more or less using ChatGPT as an advanced search engine, and the results of using the AI amazed him.
He recently described a hypothetical kind of algorithm he wanted to use for Valve’s MOBA-shooter, Deadlock’s matchmaking and was stunned to receive an accurate recommendation from ChatGPT for a real algorithm meeting his requirements and specifications for the Valve Deadlock Game. According to the Valve Engineer Dunn, the algorithm recommended by ChatGPT is now being used in Deadlock’s matchmaking in the Valve Deadlock Game.
ChatGPT Wins
He wrote: “I’m gonna keep posting my ChatGPT wins, because this thing keeps blowing my mind, and I think there are some skeptics who don’t get how amazing this tool is.”
Despite the fact that he described it vaguely, ChatGPT immediately returned the matchmaking algorithm he was looking for for the Valve Deadlock Game. Although Dunn acknowledges the fact that he could have used the right Google search terms to get the same result, he points out the fact that he didn’t have to, as ChatGPT was hassle-free to use.
Dunn replied to another poster saying, “‘Find me this thing that I don’t really know the right search terms for, but I will attempt to describe’ is just a *killer* app,” and added, “A few days ago we switched Deadlock’s matchmaking hero selection to the Hungarian algorithm. I found it using ChatGPT.”
Valve Not Disclosing Generative AI on Steam
Most of the time, developers use generative AI in ways that wouldn’t be too obvious to gamers like using ChatGPT as a search engine, or as an administrative tool, or to write code, or by using image generators during the concept stages. This way, it reinforces the game’s design while perfecting it, using generative AI to create final videogame art or replace voice actors is the tip of the iceberg.
Steam added a new rule in January for game developers to disclose the use of generative AI, to be displayed to consumers on store pages, in any game submitted on the platform. With that said, not a single one of Valve’s games discloses any use of generative AI for the game’s content, not even the Valve Deadlock Game. Using ChatGPT as a natural language search engine for Deadlock’s matchmaking more or less doesn’t count as the sort of thing that requires disclosing. Valve’s rules call for developers to disclose “any kind of content (art/code/sound/etc) created with the help of AI tools during development” which this wasn’t.
“I am kind of conflicted because it is often replacing asking the question to another human IRL, or at least tweeting it out to the virtual braintrust,” Dunn says. “I guess this is good (the whole point?), but it’s just another way for computers to replace human interaction.”
Conclusion
OpenAI, the creator of ChatGPT, has recently announced a remarkable achievement of raising $6.6 billion in a new funding round. According to the Associated Press, the focus of the company is now directed toward generating profits. OpenAI asserts that its latest model, ChatGPT o1, has the ability to engage in “reasoning” when faced with challenges. This latest model would have done a better job at the matchmaking algorithm for the Valve Deadlock Game and who knows, this AI may be used later in the game.
