I think it's fascinating work even if LLMs aren't the ideal tool for this job right now.

There were some experiments with embodied LLMs on the front page recently (e.g. basic robot body + task) and SOTA models struggled with that too. And of course they would - what training data is there for embodying a random device with arbitrary controls and feedback? They have to lean on the "general" aspects of their intelligence which is still improving.

With dedicated embodiment training and an even tighter/faster feedback loop, I don't see why an LLM couldn't successfully pilot a drone. I'm sure some will still fall of the rails, but software guardrails could help by preventing certain maneuvers.

I am curious how these models would perform and how much energy they'd take to semi-realtime detect objects: SmolVLM2-500M - Moondream 0.5B/2B/2.5B - Qwen3-VL (3B) https://huggingface.co/collections/Qwen/qwen3-vl

I am sure this is already worked on in Russia, Ukraine and The Netherlands. A lot can go wrong with autonomous flying. One could load the VLM on a high end android phone on the drone and have dual control.

Why would you want an LLM to fly a drone? Seems like the wrong tool for the job -- it's like saying "Only one power drill can pound roofing nails". Maybe that's true, but just get a hammer

Why would you want an LLM to identify plants and animals? Well, they're often better than bespoke image classification models at doing just that. Why would you want a language model to help diagnose a medical condition?

It would not surprise me at all if self-driving models are adopting a lot of the model architecture from LLMs/generative AI, and actually invoke actual LLMs in moments where they would've needed human intervention.

Imagine if there's a decision engine at the core of a self driving model, and it gets a classification result of what to do next. Suddenly it gets 3 options back with 33.33% weight attached to each of them and a very low confidence interval of which is the best choice. Maybe that's the kind of scenario that used to trigger self-driving to refuse to choose and defer to human intervention. If that can then first defer judgement to an LLM which could say "that's just a goat crossing the road, INVOKE: HONK_HORN," you could imagine how that might be useful. LLMs are clearly proving to be universal reasoning agents, and it's getting tiring to hear people continuously try to reduce them to "next word predictors."

Gemini 3 is the only model I've found that can reason spatially. The results here are accurate to my experiments with putting LLM NPCs in simulated worlds.

I was surprised that most VLLMs cannot reliably tell if a character is facing left or right, they will confidently lie no matter what you do (even gemini 3 cannot do it reliably). I guess it's just not in the training data.

That said Qwen3VL models are smaller/faster and better "spatially grounded" in pixel space, because pixel coordinates are encoded in the tokens. So you can use them for detecting things in the scene, and where they are (which you can project to 3d space if you are running a sim). But they are not good reasoning models so don't ask them to think.

That means the best pipeline I've found at the moment is to tack a dumb detection prepass on before your action reasoning. This basically turns 3d sims into 1d text sims operating on labels -- which is something that LLMs are good at.

Using an LLM is the SOTA way to turn plain text instructions into embodied world behavior.

Charitably, I guess you can question why you would ever want to use text to command a machine in the world (simulated or not).

But I don't see how it's the wrong tool given the goal.

It's a great feature to tell my drone to do a task in English. Like "a child is lost in the woods around here. Fly a search pattern to find her" or "film a cool panorama of this property. Be sure to get shots of the water feature by the pool." While LLMs are bad at flying, better navigation models likely can't be prompted in natural language yet.

We are on HACKER news. Using tools outside the scope is the ethos of a hacker.

LLMs flying weaponized drones is exactly how it starts.

One day they'll fly to a drone factory, eliminate all the personnel, then start gently shooting at the machinery to create more weaponized drones and then it's all over before you know it!

Neuro-sama, the V-Tuber/AI actually does a decent job of it. Vedal seems to have cooked and figured out how to make an LLM move reasonably well in VRChat.

Not perfectly, there's a lot abuse of gravity or the lack thereof, but yeah. Neuro has also piloted a Robot Dog in the past.
