Ubisoft NEO NPC: What We Know, What Ubisoft Said and What Happened Next

NEO NPC is a prototype from Ubisoft’s Paris studio, shown at GDC in March 2024, that lets a player talk to a game character in their own words and get a reply that stays in character. Ubisoft built it with Inworld and NVIDIA. It was widely covered at the time, and more than two years later it is still a prototype, not a feature of any game you can buy.

This page separates what Ubisoft actually said from what was said about it. If you are looking for games you can play today with AI characters, our games with AI NPCs guide lists the ones we could verify, and NVIDIA ACE explains one of the tools behind the demo.

This page is built from Ubisoft’s own article about NEO NPC and from press coverage of GDC 2024 and of Ubisoft’s later work. We have not played NEO NPC, which was shown in demonstrations, and nothing here is scored. It is read, not played. Ubisoft’s article gives no release date.

The Short Answers

What is it? A prototype that explores open-ended conversation with game characters.
Who made it? A small R&D team at Ubisoft’s Paris studio, with Inworld’s language model technology and NVIDIA’s Audio2Face facial animation.
When? Presented at GDC in March 2024. Ubisoft’s article is dated 19 March 2024.
Can I play it? No. It is a prototype, with no stated plan for a specific game.
What happened next? In November 2025 Ubisoft revealed a related prototype called Teammates, according to press coverage. We found no NEO NPC release.

What Ubisoft Says It Is

Ubisoft’s article describes NEO NPC as a project to find out whether players can have open, spontaneous conversations with characters instead of picking from fixed dialogue lines, while the characters stay believable and in character inside their setting. The partners are named plainly: Inworld’s large language model technology, and NVIDIA’s Audio2Face application, which turns speech into facial animation as it is produced.

Press coverage at the time called it Ubisoft’s first player-facing generative AI prototype, and said Ubisoft showed three demonstration scenarios at GDC. We did not find a primary source for the scenario details, so we do not describe them here.

How the Characters Were Written

The most interesting part of Ubisoft’s article is that the characters were not generated. People wrote them.

The writing. The article says narrative director Virginie Mosser spent more than a year creating the characters: their backstories, hopes, personalities and ways of speaking.
The training. Data expert Mélanie Lopez Malet works on getting the model to behave like those characters, using guardrails, analysis of the choices players make, 3D environments and text instructions. The team repeatedly checks whether the model’s answers fit the character, and corrects it when they do not.
Why this is needed. The article says a basic language model gives flat, robotic answers. Conditioning it on a writer’s story, personality and voice helps it stay consistent.

That is the same split that our Inworld AI guide describes from the vendor’s side: humans write who the character is, and the model improvises what they say.

How Ubisoft Says It Stops Them Going Off the Rails

Open conversation is easy to break. The article describes four controls.

Control	What Ubisoft says
Filters	They catch toxic or inappropriate player input
Character reactions	The team separates a player who is merely contrary from one who is insulting, and the character becomes uncooperative toward toxic input
Scenario limits	Characters are designed to stay within the scenario’s story and ending
Human checking	The team keeps testing the replies and correcting the model

The Problems Ubisoft Admitted

Ubisoft’s article is unusually frank about what went wrong.

Stereotypes. The model showed stereotyped tendencies. The article gives the example of an attractive female character whose replies leaned toward charm and seduction, so the team had to reprogram her.
Absurd input. Nonsensical answers from a player can derail a scene, so the team plans for them.
Delivery. The team believes expressive human acting is essential to convincing characters. A model’s words alone are not enough.
Not ready. The article says much work is needed before the technology could be used in a game. Its stated goal is a flexible tool that could serve both small and AAA Ubisoft projects.

Why There Is Still No NEO NPC Game

The article gives no release date and names no game. We found no Ubisoft release that credits NEO NPC. We cannot say why, because Ubisoft has not said, but the problems above are the likely ones to be hard: authoring a character takes a year of a writer’s work, and the failures are the kind that appear in front of players.

What Happened Next: Teammates

In late November 2025, press coverage reported that Ubisoft had revealed Teammates, a first-person shooter prototype in which AI squad members respond to a player’s voice commands, adapt to each situation and have distinct personalities. Ubisoft is said to describe it as building on NEO NPC, which had conversation and reasoning but a static environment, and to have tested it with a limited number of players in a closed beta. One outlet’s report says it is described as an experiment in new ways to create interactive stories, not a commercial product.

We read this from press coverage, not from Ubisoft’s own announcement, and reports differ on the technology behind it. We found nothing about Teammates dated 2026.

What NEO NPC Tells You About AI Characters

Conversation is the easy part. Writing a character who stays interesting and safe is the work, and it took a year of a narrative director’s time.
Guardrails are a design job. Ubisoft did not rely on one filter. It combined filters, character design and constant testing.
A talking character needs a story to stand in. Ubisoft says its characters stay within the scenario. That is a very different promise from the open worlds in our AI RPG platform reviews.
Studios are cautious. More than two years after the demo, the big-studio version is still in prototype.

A Short Timeline

19 March 2024	Ubisoft publishes its article on NEO NPC and presents the prototype at GDC	Ubisoft News
March to September 2025	Inworld stops presenting itself as a character engine for games and retires Character Studio	Our Inworld AI guide, from Inworld’s own website

The middle rows matter. The company that supplied the language model technology for NEO NPC changed what it sells while the prototype was still a prototype. That does not mean the prototype’s technology disappeared, and Ubisoft’s article does not say which model runs it today. It does mean the 2024 line-up of partners should not be read as a current one.

How to Judge a Talking-NPC Demo

NEO NPC is a useful yardstick because Ubisoft listed its own problems. When a studio or a platform shows you an AI character, ask the same questions.

Who wrote the character? A year of a narrative director’s work is a different thing from a paragraph of backstory.
What is the character allowed to talk about? A character fixed to one scenario is easier than one in an open world.
What happens when you are rude, or silly? Ubisoft says the character turns uncooperative. Not every demo shows this.
What does the model get wrong? Ubisoft named stereotypes. A vendor that names no failures has probably not looked for them.
Is it a live demo, or a recording? The demo floor at GDC is a controlled setting.
Can you play it at home? If not, you are judging a pitch.

The same questions work on the games in our games with AI NPCs guide, where each entry is checked against its own store disclosure.

What We Could Not Confirm

The scenarios shown at GDC. We did not find a primary source for the details.
The model behind the characters now. Ubisoft’s article names Inworld in 2024. Inworld has since changed its business, as our Inworld AI guide explains.
Teammates’ technology and test. Our information is from press coverage and differs between outlets.
Any 2026 status. We found no update.

Frequently Asked Questions

What is Ubisoft NEO NPC?

NEO NPC is a prototype from a small research and development team at Ubisoft’s Paris studio, shown at GDC in March 2024. It lets a player have open-ended, spontaneous conversations with a game character, instead of choosing lines from a dialogue tree, while the character stays in character and in the story.

Can I play NEO NPC?

No. Ubisoft describes it as a prototype and its own article gives no release date or plan to put it in a specific game. It was shown in demonstrations.

Who made NEO NPC?

Ubisoft’s Paris R&D team made it, working with Inworld, whose language model technology drives the characters’ conversation, and NVIDIA, whose Audio2Face tool animates their faces in real time. Ubisoft’s writers created the characters.

How does Ubisoft stop NEO NPCs saying anything?

According to Ubisoft’s article, the team uses guardrails, text instructions, and analysis of player choices. Filters catch toxic or inappropriate input, and a character can turn uncooperative toward it. Characters are also written to stay within the scenario’s story and ending.

What problems did the NEO NPC team report?

Ubisoft’s article names three: a basic language model gives flat, robotic answers; the model showed stereotyped behaviour, for example one attractive female character leaned toward charm and seduction until the team reprogrammed her; and nonsensical player answers can derail a scene.

Is Ubisoft Teammates the same as NEO NPC?

No, but it builds on it. Press coverage from November 2025 describes Teammates as a first-person shooter prototype where AI teammates respond to voice commands, and says it extends NEO NPC, which had conversation and reasoning but a static environment. It was in a closed test, not on sale.

Does any released game use NEO NPC?

We found none. Ubisoft’s article says much work is needed before the technology could be used in a game, and we found no Ubisoft release that credits it.
