What is Los Santos Alive?
Los Santos Alive is a mod for Grand Theft Auto V (Legacy & Enhanced) which integrates generative AI into NPC interaction.
NPCs can be communicated with naturally using either text or microphone input, with conversations and responses occurring dynamically in real time.
When approached, NPCs are aware of contextual information such as:
their role in the world
nearby streets and locations
weather and time of day
whether they are indoors or outdoors
nearby activity and events
vehicles, music, and environmental details
As interactions continue, the system begins forming a broader understanding of who an NPC is within the world.
Depending on the interaction and context, NPCs may begin developing inferred routines and behaviors, such as:
work schedules
leisure habits
sleep routines
places they frequently visit
Over time, NPCs may dynamically appear throughout the world carrying out these routines naturally.
Los Santos Alive also aims to make the world reactive to player behavior.
Crimes and major events can persist within the world and spread organically depending on factors such as:
severity
distance
recency
and personal relevance to nearby NPCs
An event occurring in one part of Los Santos may later be discussed elsewhere by completely different NPCs, with reactions varying depending on who is being spoken to and how connected they are to what happened.
In addition to conversation, NPCs are capable of physically responding to the player through in-game actions and dynamic behavior.
The goal of Los Santos Alive is not simply to create smarter dialogue, but to make Los Santos feel inhabited by people who exist within the world around them.
