A survey conducted about a year ago found that 31% of game developers were already using generative AI in some way. I'd wager that the percentage has increased significantly since then.

We know Valve is using it: Fletcher Dunn, an engineer who's been with Valve for over a decade, has been posting his "ChatGPT wins" on X, saying today that OpenAI's large language model is an "amazing" tool.

Dunn is more or less using ChatGPT as an advanced search engine, and the interaction that amazed him recently saw him describe a hypothetical kind of algorithm he wanted to use for Valve's MOBA-shooter, Deadlock, and receive an accurate recommendation for a real algorithm matching his specifications. The algorithm ChatGPT recommended is in fact now being used in Deadlock matchmaking, according to Dunn.

"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," he wrote. "A few days ago we switched Deadlock's matchmaking hero selection to the Hungarian algorithm. I found it using ChatGPT."
