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.
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.
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.
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.
The first thought I had was those security guard robots that are popping up all over the place. if they were drones instead, and LLM talked to people asking them to do/not-do things, that would be an improvement.
Or an waiter drone, that takes your order in a restaurant, flies to the kitchen, picks up a sealed and secured food container, flies it back to the table, opens it, and leaves. It will monitor for gestures and voice commands to respond to diners and get their feedback, abuse, take the food back if it isn't satisfactory,etc...
This is the type of stuff we used to see in futuristic movies. It's almost possible now. glad to see this kind of tinkering.
You describe why it would be useful to have an LLM in a drone to interact with it but do not explain why it is the very same LLM that should be doing the flying.
You don't want an LLM to drive a car
There is more to "AI" than LLMs

I've been working with integrating GPT-5.2 in Unity. It's fantastic at scripting but completely worthless at managing transforms for scene objects. Even with elaborate planning phases it's going to make a complete jackass of itself in world space every time.
LLMs are also wildly unsuitable for real-time control problems. They never will be. A PID controller or dedicated pathfinding tool being driven by the LLM will provide a radically superior result.
This looks like a pretty fun project and in my rough estimation a fun hacker project.
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."
