Easy Fox borrowed to keep the free Steam demo of Teach My Little Sister How To Drive running after a surge in players drove its AI service bill above $1,000 a day. The studio reported that demo players had grown more than twentyfold in a month; the loan addressed the immediate operating shortfall, not the separate access limits affecting its primary AI model.

Why the demo became expensive to run
In the game, players sit in the passenger seat and guide a driving student with voice instructions. External AI models handle real-time conversations, making AI services part of the ongoing demo experience rather than a one-time development expense.

The studio’s October update said it was spending more than $1,000 daily on AI services and had borrowed to keep the demo available. SteamDB recorded an all-time concurrent-player peak of 431 on October 1, 2026.

37 The studio linked the rising operating bill to the increase in players; the available reporting does not disclose the loan amount or its terms.
More players also meant model access problems
The financial pressure was not the only issue. Easy Fox said its primary model, Gemini, began frequently returning usage-limit errors after the player increase. The studio said it contacted Google Cloud about raising its usage tier, but was told a manual increase was not available.

The developer’s AI information identifies Gemini 2.5 Flash as the primary model, while interview coverage describes OpenAI Realtime as an alternative. That coverage also reports problems with in-game responses amid model limits.

How Easy Fox says it plans to handle AI costs
For the paid game, Easy Fox has said it intends to account for expected AI-token use in the purchase price rather than charge players separately.
8 That is a proposed pricing approach; it does not establish that the game’s ongoing service costs are already sustainable.
The studio also indicated that it might end the demo earlier than planned because of the financial burden. The reports describe this as a possibility, not a confirmed shutdown.

What the reporting does not establish
The available sources explain the immediate reason for the loan: rising AI operating costs tied to the demo’s growing audience. They do not verify the studio’s alleged original no-borrowing policy, the loan’s amount or repayment terms, or the specific local-AI hardware requirements raised in the question. Those details should not be treated as confirmed.
