I built a low-latency AI companion that plays Skyrim with me

I must say absolutely hilarious video. The "persona" of the dog is great. As someone who is generally pretty "keep your AI out of my art" this looks very fun to play. I can imagine this being cleverly integrated as a primary feature of a game (this must already be in the works). Ideally as a small model able to run locally alongside the game.

The moment where the dog is going on about "something foul in the air" as the player is attacked by a wolf ("F--- dude you could have warned me!") was great comedy.

I get it is fun to play for an hour or so then you inexorably encounter behaviors that are too complex to handle, e.g. you try to sneak in on an enemy but get spotted because the dog started talking or barking randomly, then suddenly wonder how much "it" actually gets it. You then start with less and less complex plans... until you realize that direct commands or shortcuts are more reliable.

I do think it is an interesting exploration but the jagged frontier makes it really challenging to know what will consistently work and what will not, to the point that I bet (maybe pessimistically) one will be gradually less daring with creative plan with their "companion" simply because they can't trust it.

I feel like that's the benefit to the creator having made this a dog (even if a demon-possessed dog). As intelligent as a dog can be, can we ever truly understand why they do the things they do?

The Uncanny Valley effect would be too big if a human companion randomly started talking to you while you were sneaking up on an enemy. But a dog? You'd be pissed off at it for a bit, and then forgive it because it's a dog.

"But a dog? You'd be pissed off at it for a bit, and then forgive it because it's a dog."

Some grumpy old school hunters (in less civilized areas) would literally shoot such a dog though for barking in the wrong moment.

Except it is not a dog. It is an AI. It’s a character in the game.

People often love to fus ro dah Skyrim companions off of cliffs because they can be incompetent annoying little dumb things that won’t shut up.

The character taking on canine form won’t suddenly make gamers more likely to put up with it messing about their gameplay. Thats just not how things work.

by kdkdjfjejd

So, this is what I have been thinking (and part of the reason why I want to "cook" it more before shipping). Since I have been building it for so long, I am not sure how much "overfit" it is on my data, the way I speak and the phrases I 'm using.

And of course the opposite too, how much the dog trained me to speak to it a certain way to maximize outcome success.

But then I thought, when people play games they are not using highly sophisticated vocabulary and there is probably lots of repetition since they are always under some form of multi-tasking stress (playing and replying/speaking). So maybe... maybe, the system can adjust itself. Use a big LLM offline to say "user said X, we did Y - was that good?" - then retrain itself.

The decomposer is basically a bunch of old-school embeddings/classifiers stitched together, it can train super fast and doesn't need tons of data. Could the thing calibrate itself to the user? Does it even need to? (because as I said I 'm a datapoint of 1 and I am not ready for the potentially huge stream of bug reports when I ship (add some perfectionism to the mix and you get the idea)).

That's absolutely my thought too.

When watching the vids, I remembered talking (mostly text chat) in MMORPG's 20 years ago. Even when we started using Skype, etc., chatting was frequently short, slang, and quick info. Like, "pulling", "OTM", "BRB", "OOM". Or even just "let's go", and so on.

But with some practice sessions, I suspect this system would pretty quickly gravitate to using any players slang speech. Am I wrong?

Kinda in the same vein, been reading/listening to Dungeon Crawler Carl lately. One of the main characters is a tortoise shell cat that gains sentience. One of the more fun aspects in the early books is the main character Carl dealing with that cat being loud, not aware of her surroundings, and making it difficult to sneak around an RPG style dungeon.

Also the author really gets the "tortitude" right.

Indeed. Can’t wait until they sell me a subscription to a game that I will just look at while an AI plays and has fun for me. Whee! Awesome times ahead indeed.

Or maybe it won’t play the game for me but will do whatever it wants, mess up about my gameplay because it inferred it should do something I did not order it to do.

Either way, awesome! Lovely gaming experience. I remember being a kid and thinking “wouldn’t it be so much more fun it if I didn’t have to actually play the game?”.

by kdkdjfjejd

8/24/2026 at 7:39:05 PM

you lack imagination. AI will not play the game for you.

It will construct the game around you as you play. It will customize the game according to you and the situation dynamically.

The first step is AI npcs and AI generated quest lines.

The next step is the entire world, the entire story, the entire game will be dynamically constructed as soon as you start it up.

by threethirtytwo

8/24/2026 at 8:06:47 PM

I've noticed that the main (socially acceptable) use for AI in entertainment seems to be laughing at how bad it is. When it fucks up something obvious that any human would know not to do. When it does something so insane and out of left field that it takes you by surprise and makes you laugh. This seems to fall under that category.

I've noticed this too as a DougDoug fan. He seemed to be genuinely confused by general strong opposition to AI from his audience despite a lot of his content, including some of the most well-received videos, being AI-focused. I think the secret is exactly what you describe - his AI characters tend to be extremely deranged and incompetent which is what makes them hilarious.

>The game runs on Windows, the audio processing and brain runs on my M4 MacBook. It could all run on Windows (provided there is dedicated ~12gb or more gpu ram for it)

I do wonder if this is an avenue for console gaming that might be practical in a few years; AI-centric hardware that might be too beefy or expensive for regular users, but can extend new or existing games. Kinda like the expansion paks of old.

unfortunate that the "ALE" design wasn't opensourced (couldn't find a link in their post) but I would be interested in learning more about the design, in particular what sort of data pipeline was necessary from skyrim to give this sort of action flexibility?

by usernomdeguerre

8/24/2026 at 5:02:03 AM

I will be open sourcing it soon :) my code is a bit dirty (the whole system is 3 pieces. The game adapter / a websocket bridge between game and brain / the brain itself) and it runs on 2 different (local) machines currently.

Ale is what makes this work locally, I felt a little conscious about it as I am not sure if it is a novel approach or somebody comes out and claims I rediscovered BERT or something (though ale runs at 1/10 the cost of BERT).

by pantelisk

8/24/2026 at 10:33:18 AM

As soon as the AI progress 'slows down' a little bit and its a little bit more clear what makes sense of converting into a hardware model, there will be for sure something.

It either might be some neural engine like what Apple is doing and tensor units like what high end android phones already have or something dedicated.

Based on the current capacity issues around the globe, perhaps 1-5 years?

But we have for sure crossed a price point were you just might buy 10 ai credits and will be able to just play 100h without running ot of your ai credits. basic conversations etc. finetuned for a game, doesn't need a frontier model.

If the AI Bubble bursts a little and the inflated prices for tech dwindle down to normal maybe, otherwise, it will be too expensive.

Or some other advancement that challenges the giants financially but incentivizes companies to build for local AI usage.

I get how you utilize embeddings, but most interesting part for me is how you decompose multiple commands? You decompose sentences before embedding?

by Xx_crazy420_xX

8/24/2026 at 3:55:20 AM

I like the approach here. It’s cleverer than just “dump context to LLM”. I couldn’t quite figure out if it genuinely runs purely locally though.

If nothing else - this is how NPCs should work in games moving forward!

by rao-v

8/24/2026 at 4:35:35 AM

Hello, author here. I was intentionally a little vague about this because this is kind of the thing that makes the whole approach work.

An LLM predicts the next token. If you're trying to predict the next token in a mathematics competition, or while playing a deep strategy game, being a much larger and more capable model helps enormously. To predict that next token correctly, the model effectively needs to model a bunch of possible future states - even if that is a second order (unintended) effect, it is what is seems to be happening.

This is basically the Ilya (and Dario) argument that prediction, understanding, and compression are the same thing (deep rabbit hole) from a few years ago.

----

In my opinion; this is a beautiful idea, but videogames do not need most of that. Videogames (and games in general) shine when character behavior is predictable, and when NPCs are a little dumb (just a little).

We already have very good small roleplaying models — Qwen 3.5 4B/9B/30B-A3B. Nowhere near frontier models at general reasoning. But they can act and write in a very engaging way. Good at roleplaying but very weak at reasoning. They just need a little nudge at reasoning...

And that's the key. The player has already expressed their intent: attack that guy, go look over there, cover me, find the key that shines and is golden, etc. A constrained world, with a constrained set of actions. Instead of asking the model to reason over an enormous space of possible futures, we're mostly asking it to map: player intent + current world state → a small sequence of plausible actions.

As for the "dump context to an LLM". It's basically. "You are roleplaying as X - you experienced Y - you like/dislike (dispositions) Z, you remember Alpha, your journal says Delta. Player orders you to do Gamma. - "What do you respond and do?"

It kind of works (as you can see in the videos I posted). I am not going against the grain, big models are better, but do we need those models for everything?

by pantelisk

8/24/2026 at 8:16:24 AM

What I don't understand is how are you passing the world state to the model?

Say for instance when you ask the dog to do an action when you launch an arrow upwards how is the LLM continuously tracking the state of the game to be able to respond?

by alwaysanoobie

8/24/2026 at 8:43:24 AM

At that point it's deterministic and doesn't need the LLM. Once a plan has been decomposed and evaluated, it becomes a sequence of actions. Actions can either wait on a trigger or flow from one to another.

For the arrow example: wait here -> bind: arrow event -> pick_up $target -> goto player -> drop $target.

A plan can bind to multiple steps and actions. eg you can tell the dog, "when I say apple you say banana" this creates a short lived "player has said %apple%" -> say "banana" rule. Hide and seek does "say: count to 10" (this then gets fed to llm that converts it to "one, two, three"). So, the plan decomposition is fuzzy, but it gets decomposed to concrete steps, these steps might invoke the LLM back if needed so, but mostly for color, not logic.

Where the LLM is used afterwards, is for evaluating the result. The dog might ask for a treat if it got right or get frustrated is it misses a beat, etc (depending on emotional state, hunger levels, etc).

Basically trying to use the best of each system (fuzzy/vague/emotional for LLM, "hard" game actions for determinism). You can think of Ale's output as a small flowchart.

I am using a pretty dumb model. It's great for speaking, terrible for thinking, so there's a need for creativity

by pantelisk

8/24/2026 at 4:34:12 PM

I think what's still a bit unclear is how the action space gets linked to a plan. Did you create your own action prototypes, or are you using ones exposed via an existing Skyrim world state interface layer?

How often are you running the world JSON through the planner? When do you give up on fuzzy matching if an action doesn't fit?

Do you use any vision tools? such as the plugin from https://github.com/MinLL/SkyrimNet-GamePlugin

Super cool project btw, thanks for sharing!

by herpdyderp

8/24/2026 at 8:28:47 AM

This is the sort of thing that the GPT-Live model would excel at when it launches. I'm not sure you'd need the ALE model at all if they launch Live in the API with acceptable pricing as it solves the latency issues with voice entirely. It's an impressive piece of engineering that hasn't been discussed much yet, I guess because it's only a ChatGPT feature and not accessible to developers. The model can dispatch tools asynchronously while speaking which would be ideal for a game.

What you'd want is maybe some kind of Live model with voice warping so it can be given different Skyrim themed 'Nordic' voices, and then custom tools to interact with the game engine.

by mike_hearn

8/24/2026 at 3:39:05 PM

This is part of the reason I wanted to announce it even before I feel ready to ship... The frontier models have such crazy velocity (admirable) and moving so fast that I didn't want them to make an announcement and suddenly trivialize all the work I 've put into this, overnight.

The fun technical challenges (that can also act as any sort of weak moat) are being taken away one by one, on an almost weekly cadence now! :)

This is a fantastic application of an LLM. What’s great is that the LLMisms fold neatly into “dumb but lovable sidekick”.

So even when it chokes or stumbles on a command, the kind of frustration the user expresses when correcting it feels natural and part of the game even.

>It creates embeddings from the full text as well as its extracted structure, then semantically combines and compares it with action prototypes. A separate classifier estimates whether the turn is a command, question, chat, clarification or complex request. Everything gets merged together.

Does this mean the prototypes and classifications need to follow what you can actually do in the game? Were they all hand-coded or generated somehow?

Nice demo, I'm always impressed by making these things low latency enough to be actually interactive. Were you inspired at all by the autonomous vtuber Neuro-sama recently getting some in-game integrations to allow her to play Skyrim on her own?

by Jach

Some variant of this idea has played in the back of my mind over the last few years. I'd love to play Skyrim, but where each character builds their own context for their history, their personality, their goals, and their interactions with you. The world would feel incredibly alive.

Yes, the dog has a few levers including a "boredom" counter that will trigger it to do things on its own (like roam around, eat something, chase something (eg a rabbit) if there's one around etc). All connected with its current state (Eg hungry = will probably prioritize eating but not guaranteed). Other things are mapped to game events. Deterministic in nature but its underlying values can evolve over time (both its default "homeostasis value" but also the curve of which it increases). You can think of it as letting an llm design a behavior graph, and then playing that behavior graph until it changes again.

Talking to it alleviates pressure so that mechanism doesn't fire much, but in the void-mode video on the website, at the very end, it chooses to chase down an elk on its own much to my surprise.

After play testing it I had to tone it down quite a bit as it caused continuity issues...

In one scenario the dog was hungry so he went and ate something that was owned (counts as a crime attributed to the player) so we ended up in jail. Being transported to jail fired a new location event and a switch from "exterior->interior" which the dog responded to by having the llm author something along the lines of "It's nice to be finally indoors, it was getting cold outside". Which made for a very funny moment but a frustrating gaming experience.

One: do you really want that? There is such a thing as too much realism in a video game.

Who would want to have a non-deterministic, unreliable, out-of-your-control companion in a single player game?

What kind of game designer would find it acceptable to have no control over large swathes of their own game? Who would like to play a game that no one really created?

by snowram

I'm especially interested in how this can be applied to the world of the game. I think that creates much more interesting results than NPCs who can hold dynamic conversation.

by pphysch

8/24/2026 at 9:54:25 AM

One challenge I see is that to work well and stand above 'easy' implementations the game would need to provide a rich context for the AI to exist in and interact with. Skyrim is a richly detailed world with an engine that allows that level of interaction, especially as it builds upon earlier elder scrolls games. Then there's the factor of whether commercial studios with the capacity to make that world in the first place (which has been a major draw for players) will invest further budget into AI to add more value, and if they have options to see a return on that investment via the main purchase price or additional costs.
