inZOI’s Smart Zoi feature represents an ambitious leap in gameplay mechanics, powered by experimental AI technology designed to enhance immersion. This system transforms NPCs into more interactive, semi-autonomous co-playable characters by allowing players to do unique customizations to their action flow without directly playing with them.

By giving them their own “inner thoughts” and
logic-driven behavior
, the Smart Zoi feature promises to elevate gameplay in a meaningful way. Here’s all that players need to know about Smart Zoi feature, and its limits.
Since Smart Zoi is an experimental addition during game’s early release, it may not always function as expected. Bugs, performance issues, or inconsistencies are expected to arise, particularly given the complexity of AI integration. Furthermore, it requires players to have high PC specs to run smoothly. Still, for those with capable systems and a tolerance for occasional hiccups, this feature can be quite worth trying out.
How to Enable Smart Zoi in InZOI
In order to enable the Smart Zoi function requires players to
access Gameplay tab in the Settings Menu
– accessible through ESC button. This feature will be visible below the Freewill section. Activating this feature by default impacts the entire city, meaning it applies citywide and influences most of the Zoi within the simulation.
However, players will be able to adjust specific settings related to Smart Zoi, including its application range in the city, screen as well as queue limit. This means that players who want to try out this feature despite having performance issues can limit it to reduce resource usage if necessary.
Players can also disable the Smart Zoi through the same section in the settings.
Recommended Graphics Settings for Smart Zoi in InZOI
InZOI already comes with
relatively high PC requirements
, and Smart Zoi pushes this even further. When activating Smart Zoi, players will encounter a pop-up prompt recommending adjustments to their graphical settings. This system automatically lowers all settings by one level—for example, High becomes Medium, Medium becomes Low, and so on. While this is intended to optimize performance, it’s worth noting that these changes will impact the visual fidelity. It is strongly advised to disable Smart Zoi on systems that struggle with performance, as the feature can be resource-intensive.
For those with lower-end processors or GPUs, such as the NVIDIA 10 series or older, the Smart Zoi feature will not be available.
What Does the Smart Zoi Feature Do in InZOI?
The Smart Zoi feature intends to change the action pattern of NPCs, through the integration of AI-driven behavior instead of traditional NPC programming. This allows them to autonomously make decisions, engage in activities, and interact with the world based on their “inner thoughts.” These thoughts guide their actions.

For example, a Smart Zoi might decide to take up a hobby, build relationships, or even tackle specific tasks based on its personality traits and the situations it encounters. The feature also ties into the in-game Thought System, ensuring that decisions feel purposeful and logical. While players cannot directly control these CPCs, they can influence their actions by interacting with them or observing their thought processes. However, since this is an experimental feature, players may not notice too much change in their actions, especially if their prompt is relatively vague. Additionally, since their needs should still take over, it may take a while until their new actions are processed.
How to Customize Smart Zoi in InZOI?
The customization options
for Smart Zoi can be considered in two separate ways, one through Gameplay Settings menu as previously mentioned, customizing the NPCs that will have the Smart Zoi integration. Additionally however, players can also assign unique personality traits or actions via Smart Zoi by clicking any Zoi, tailoring their thought patterns and decision-making processes.
For instance, instead of leaving the blank description, players can choose to write a prompt for the Zoi to always be kind and friendly to others, while another Zoi could be prompted the entirely opposite way. However, especially due to the experimental aspect of this function, some prompts or preferences might need more tailoring, since some non-specific prompts may simply not show the desired result. In short, there is quite some trial and error as well as patience, as the system requires time to show meaningful changes in character dynamics.
