Easy Fox Faces $1000 Daily AI Costs for Driving Sim Demo

Easy Fox is struggling to maintain the free Steam demo for Teach My Little Sister How To Drive after the AI-powered driving simulator attracted a surge of players and pushed operating costs above $1000 per day, according to the developer on October 10.

The four-person studio said demo users increased more than twentyfold over the previous month, creating unexpected expenses from AI conversations that power the game’s interactive sister character.

According to Easy Fox’s Steam update, the team originally connected players to Google’s Gemini service, but rising usage caused limit errors. The studio later relied more on OpenAI Realtime models while seeking a longer-term solution.

"Over the past month, the number of demo players has grown more than twentyfold. Thank you so much for giving our game far more attention than we ever expected. This growth has also increased our operating costs considerably." said Easy Fox, the developer.

The studio said it took out a bank loan to keep the demo available after deciding the expenses had become too difficult to cover. Easy Fox has not announced a shutdown date but warned financial pressure could end the demo before the full release.

Easy Fox said the game’s AI behavior has also faced technical issues, including responses and actions that do not always match player instructions. Some unpredictable behavior is intended because the character is designed as an inexperienced driver, while other problems are linked to service limitations.

"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." said Easy Fox, the developer.

The studio is exploring ways to reduce cloud AI expenses, including local processing options. Easy Fox estimated that a suitable local model could require about 8GB of VRAM or more, with additional capacity needed for local voice generation.

Easy Fox plans to account for AI expenses in the purchase price of the full game rather than charging players separately for usage. Teach My Little Sister How To Drive is currently targeted for release in January 2027.
