Easy Fox says it is spending about $1,000 a day to run the demo of Teach My Little Sister How to Drive, whose player numbers have grown more than twentyfold over the past month. The four-person studio says it took out a bank loan to help cover costs and may close the demo before the full game is released, though it has not decided to do so.
Developer Easy Fox says it is spending about $1,000 a day to keep the demo of Teach My Little Sister How to Drive running, after a surge in players increased the cost of its AI-powered interactions. The four-person studio says it has taken out a bank loan to support the demo and may have to close it earlier than planned, but has not made that decision.
Easy Fox said, in a statement reported by FRVR, that the number of people playing the demo had grown more than twentyfold over the past month. The studio said the increase had raised operating costs considerably. The report puts the demo’s running costs at about $1,000 per day; it does not specify the precise accounting period or provide a breakdown of expenses.
The game uses Google Gemini and ChatGPT to power a character who responds dynamically to players’ driving instructions. Each exchange can prompt additional AI requests, which use tokens and can add to operating costs as activity rises. Easy Fox said the overall bill has increased because so many people are playing, not because any one player is particularly expensive to support.
The studio said it plans to include anticipated AI costs in the price of the paid release. Players who buy that version will not be billed separately for individual token use, according to Easy Fox. The team is also investigating support for local AI models for players with sufficiently capable computers, which could change how some interactions are run.
A Popular Demo With Rising AI Bills
The situation shows how a successful demo can create a cost problem when its central feature relies on repeated calls to paid AI services. More players mean more conversations with the in-game character, and those requests can make the service bill rise alongside the audience. For a small studio, that makes popularity itself a potential financial strain rather than an unqualified benefit.
It also puts a practical question behind AI features in games: who pays for continued model use after launch? Easy Fox says its planned approach is to account for expected usage in the purchase price rather than charge players for each interaction. The studio has not shared that price or explained how it would handle usage that exceeds its forecasts, so the long-term economics remain unknown.

How the Game Uses AI
Teach My Little Sister How to Drive is a driving-instruction simulation in which players coach a generative-AI-powered character. The character can react to instructions and, according to the report, sometimes disobey them. The demo launched in February 2026; the report says attention from streamers, including thinknoodles, helped bring it a larger audience.
AI model services commonly charge based on use, including the amount of text processed in requests and responses. In this game, interaction with the character requires AI requests, so increased play can translate into greater usage. Easy Fox has said it is exploring local models for players with capable PCs, but has not announced that this option is ready or provided a timeline.
“Over the past month, the number of demo players has grown more than twentyfold.”

Demo Closure Remains Undecided
Easy Fox has not said when the demo might close, how much it has borrowed, or how long its current finances can support operations at the reported cost. The studio says closure before the full release is possible, not settled. It has also not announced a release date or price for the paid game.
The reported twentyfold player growth is attributed to Easy Fox, and the report does not supply a starting player count or clarify the exact dates used for the comparison. Nor does it detail how much of the daily cost comes from AI requests versus other operating expenses. The studio’s proposed local-model option remains under investigation, with no confirmed launch plan.

Pricing and Demo Plans Ahead
Easy Fox says it wants to keep the demo available and hopes more people will play, but its next decision will depend in part on the financial pressure. The studio has not given a date for deciding whether to end access early. Until it announces a change, the demo remains available, according to the report.
Further details to watch for include the full release’s timing and price, how the studio estimates AI use when setting that price, and whether local models become an option. Those details would help show whether Easy Fox can keep the game’s responsive AI feature in the paid version without exposing players or the studio to unpredictable per-use costs.
