Characters that flinch before they think.

Everyone else is wiring a chatbot to a voice. Genesis is the nervous system: reflexes, perception, memory and action, modelled on how real minds work. Live today in Los Santos Alive.

The problem

Most AI NPCs are chatbots in a costume.

An LLM with a voice can chat. It doesn't know it's raining, that a gun is pointed at it, or that you robbed it last week.

What a nervous system adds

  • Flinch, duck and surrender before the model has said a word
  • Notice their own reactions, so what they say matches what they did
  • Play an authored scene exactly as written, until the player breaks it
  • Know it is raining, who is nearby and what you are holding
  • Remember people, places and promises
  • Take real actions in the game, not just talk
  • Keep talking when an AI provider goes down

Genesis Runtime · the core

You head for the car. She's already at the passenger door.

Runtime is the mind around the model. It perceives, remembers, reacts and acts. Your game just executes.

Research

Brains don't wait for a thought to pull your hand off a stove. Neither do our characters.

Every part of Genesis Runtime starts with how real minds work. A bigger model doesn't give you this. Structure around the model does.

For studios

AI characters that pay for themselves.

We've shipped AI to paying players, so we know why studios hesitate. Genesis answers all four reasons.

  1. “Who pays for every line?”

    Players do, in your store.

    Credits styled as your own currency, sold in your menus. Live AI becomes revenue, not a server bill.

  2. “Will it stay in character?”

    AAA-depth scenes, written at scale.

    Batch-generate scenes for your world, review them, ship them pre-baked. Characters improvise only off-script.

  3. “Will it say something it shouldn't?”

    Your rules hold.

    Low-latency safeguards keep conversations inside your world rules and rating, without breaking character.

  4. “Who keeps it running?”

    We do. No API keys.

    No provider accounts for players. Gateway routes around outages; model changes never need a patch.

Genesis for studios

Genesis Gateway

And they never go quiet. Every turn is routed across several speech, language and voice providers, with failover before the player notices.

How Gateway works

In production · Los Santos Alive

We're building Genesis inside the hardest test we could find: open-world GTA V.

Players speak into a microphone. Pedestrians, suspects, partners and dispatchers answer in their own voices, and act. Every Genesis system was hardened here first.

Read the case study

Police procedures

ID checks, breathalyzers, searches and arrests, all by voice.

Conversational dispatch

Talk on the radio; dispatch and units answer live, not from clips.

Autonomous partners

AI officers ride along, place cones and search suspects on their own.

Living crowds

NPCs talk to each other and react to gunfire, crashes and threats.

In players' own words

Nobody scripted any of this.

We asked Los Santos Alive players for a moment that made the world feel genuinely alive. These are their answers, word for word.

I wrote that I was crying, the lady went to other NPCs, they calmed me down.
tubinator 2.0· player for 1–3 months
Not being main character anymore but just simply a person that's interfering with what NPC's are doing.
Superkas11· player for 1–3 months
…had a conversation with a lady standing outside. We talked for awhile and she decided to ride with me to get food. Learned she was from Liberty City.

Questions

What studios and investors ask us first.

Isn't this just a GTA V mod?

Los Santos Alive is where we test. Genesis is the product. GTA V is the hardest open world we could find: police procedures, vehicles, weapons and crowds, with real players who notice every mistake. Genesis itself is designed to be engine-neutral; a game describes its world and the actions it supports, and the same characters run on top.

How is this different from wiring an LLM to a voice?

An LLM with a voice can chat. It doesn't know what is happening around it, can't react faster than it can generate text, forgets you between sessions and can't act in the world. Genesis Runtime adds the perception, reflexes, memory and actions around the model. That is the hard part, and it's what we've spent our time on.

What engines do you support?

Genesis is running in production in GTA V today. We are working with a small number of teams on integrations beyond it. Tell us your engine and we'll tell you honestly where we are.

How fast is it?

On fast routes, characters start speaking about half a second after the player stops talking. Reflexes don't wait for a model at all.

What about player data and payments?

Payments run through Stripe, so card details never touch our servers. Accounts are isolated from each other, provider keys never reach the game client, and analytics use coarse, city-level location rather than stored IP addresses.
