The next InZOI update, planned for this month in August 2026, is likely to continue with the core system changes teased in previous developer diaries. With changes being made to InZOI's Create-A-Zoi mode, mod-friendliness, and customization features, the next InZOI Update is looking to be a huge upgrade for players' quality of life.

More updates on previously teased systems have come out, like voice customization and true family creation in Create-A-Zoi, so let's dive in!
The Next InZOI Update: Coming August 2026




○ The Zoi card, the user interface menu that shows all of a certain Zoi's information, can now be used to enter Create-A-Zoi and create family members for an existing Zoi.





○ The voice customizer teased previously now has a working model, having approximately six preset voices and a slider underneath, likely for pitch. There seems to be no restrictions as to which Zois can use which voices based on gender, and there only seems to be age differences.





○ There is now a family picture generator in Create-A-Zoi that will automatically pose Zois for a family portrait.


○ A feature is being worked on that lets you take photos in-game that can then be added to picture frames in-game.



○ Dragging items is now being updated so you can take any item out of a Zoi's inventory and place it anywhere in the world, or inside of any container.




○ Toggling icons on the mini-map will now change which icons are visible in the playing environment.


○ A new button is being added on the save files menu which will take you to the directory in your drive where the save file is stored, making it easy to share or back up save files.



○ The mod manager is now being updated so it as accessible directly from any play session, meaning you don't have to back out of a save file to the main menu to use the mod manager.



○ The modkit is being updated to allow modders to change aspects of the main menu/lobby.


○ More actions are being added that can be performed while swimming like splashing others or speaking to Zois standing outside of the pool while you swim.





○ As the developers were not able to get fully free-control surfing in the game, a mini-game is being created to allow you to directionally control a Zoi who is surfing to keep balance and avoid falling over.







○ Free control scuba diving was successfully implemented and has been updated and refined since.


Next InZOI Update Developer Diary - 7/31/26 Making Things Better
Hello everyone!
I hope you're having a fantastic Friday.
It's great to see you all again.
This week, I've continued focusing on improving autonomous behavior.
Our main goal this week has been to make it much clearer why a Zoi visits a particular location.
Until now, even when Zois visited places like cafés or bakeries, they often spent most of their time wandering around, chatting with others, checking their phones, or using the restroom instead of actually accomplishing the purpose of their visit. While these behaviors help make them feel more lifelike, they occurred so frequently that many players felt it became difficult to tell what they had come there to do.
To address this, we're changing the system so that Zois will prioritize fulfilling the purpose of their visit. For example, if a Zoi visits a bakery, they'll purchase bread, go through the necessary steps, sit down to eat it, and then return home. Of course, we still want them to feel like real people, so they'll occasionally have brief conversations or encounter unexpected situations along the way. The goal is to avoid making their behavior feel overly scripted or mechanical.
We're also rebalancing how Zois spend their time at each location. Most of their actions will now be directly related to their primary objective, while random behaviors—such as looking around or chatting—will occur much less frequently. At the moment, we're aiming for roughly 90% purpose-driven actions and 10% random behaviors.
That said, making the behavior sequence too rigid can introduce new problems. For example, if there are no available seats or a required condition isn't met, a Zoi could end up getting stuck. Because of this, we're also researching ways to strengthen purpose-driven behavior while still allowing Zois to adapt flexibly to changing situations.
Another important improvement we're currently working on is changing the logic that forces Zois to stay at a location for a fixed amount of time. Instead, once they have completed their intended objective, we want them to head back home naturally.
These improvements are currently being developed for standard lots such as cafés, bakeries, and parks. Business lots and schools already have their own development plans, so they are being worked on separately.
Since this feature is still under development, we're continuing to test and fine-tune it to ensure it feels natural during gameplay. Ultimately, our goal is for Zois to do more than simply wander around a location—we want players to clearly understand why each Zoi chose to visit a particular place.
That's all for this week. We hope you enjoy this week's development video from the inZOI team, and have a wonderful weekend!
