The developer behind Teach My Little Sister How to Drive, a driving instruction sim in which players issue commands to a generative-AI-powered dynamic NPC, says it has been spending roughly $1,000 a day to keep the demo running.
“Over the past month, the number of demo players has grown more than twentyfold,” the developer said via FRVR, according to a report by Kirk McKeand for IGN. “This growth has also increased our operating costs considerably.”
According to the blog post, developer Easy Fox had to take out a bank loan to support the game, which is powered by AI models. The cost of such models can soar dramatically as user requests increase—each request consuming what the industry calls “tokens.” Teach My Little Sister constantly queries its AI as players interact with the NPC to progress.

The developer plans to factor these costs into pricing for the game’s full release. “For the paid release, we plan to account for expected AI usage in the game’s price,” they said. “Players will not be charged separately for their individual AI token usage after purchasing the game.”
This isn’t because each player is particularly expensive to support. The total cost has increased because so many people are playing, and we have taken out a bank loan to help keep the demo running.

The studio also warned that financial pressure could force it to shut down the demo early. “We want to continue operating the demo and would love for more people to enjoy it. However, we are a small team of four, and financial pressure may mean we have to close the demo earlier than expected before the full release. We have not made that decision at this time.”
The game originally launched its demo in February, but interest from streamers such as thinknoodles gave it a popularity bump. The developer also noted the game’s popularity in Asia, where there is less stigma around generative AI than in the West.
Teach My Little Sister How to Drive relies on Google Gemini and ChatGPT to power its dynamic NPC, which follows instructions, reacts, and can disobey. The developers are looking into ways of allowing local AI models to step in for players “with sufficiently capable PCs.”

The studio’s experience comes as companies using generative AI begin confronting costs. In a recent Axios report, one mystery company spent $500 million on AI tokens in a single month after failing to put usage limits on its account. Elsewhere, OpenClaw’s creator burned through $1.3 million in OpenAI API tokens in a single month.
The news also arrives amid ongoing friction between the games industry and generative AI. Recently, Capcom had to clarify comments about its proprietary RE Engine being “AI powered.”. The publisher behind Arc Raiders, per this report, came out in defense of AI use in Embark’s extraction shooter, but the team has since been making progress on replacing those stilted performances with human ones. Even games industry giant Activision has come under fire for AI usage in Call of Duty and its marketing materials.
