Declaring war on big models and bloated RL. Im training autonomous robots/vehicles by building tiny world models that are trained in 5-30 mins on a single GPU, with less than 50M params.

World model for AI agents. Doing process mining of missions, operations and logistics to transform them into digital twins. AI agents can then leverage these digital twins as world models for control or prediction.

I develop simulators for digital twins and games. Currently working on a simulator for LLMs to use as world models.

It could be the language. Almost 100% of my code is written by AI, I do supervise as it creates and steer in the right direction. I configure the code agents with examples of all frameworks Im using. My choice of Rust might be disproportionately providing better results, because cargo, the expected code structure, examples, docs, and error messages, are so well thought out in Rust, that the coding agents can really get very far. I work on 2-3 projects at once, cycling through them supervising their work. Most of my work is simulation, physics and complex robotics frameworks. It works for me.

Working on "context engineering" for coding agents. Specifically for complex dev environments and targets, like robotics, digital twins and games. Been able to witness agents go from 100% failure rate to contributing nearly 90% of the plumbing code. I'm helping agents understand how to use simulators and game engines; configure, build and deploy DevOps/MLOps pipelines.

panoc, fast, efficient, good for real-time, embedded, and adaptive control.

I’ll check what I can dig up for Rust examples.

Yang, this is really well done. I work with Rust and robotics all day, and would have never imagine seeing all this in one file. It is a great learning tool. If you complete the MPC controller it can also be a great learning tool for training AI pilots.

We ask it to predict, and in doing so it sometimes creates a model of the world it can use to "think" what comes next. In forward pass.

That’s exactly right. We, just another games and simulation studio, are implementing LLMs in several games and engines. For dialog systems, hero journeys, behavior trees and techart pipelines. Most do not even expose a chatbot to the player, LLMs are also used for game systems to chatter among themselves.

6mo+ is spot on. This is true for most dev work that deviates from the CRUD path. Like gaming, simulation, robotics. We might as well use the time to train them in Rust too.

In startups and projects where Rust is a premature optimization this makes sense. But, some startups and projects are all about the competitive advantage created by optimizing from day one. In these cases, choosing Rust and other early optimizations is the main enabler of a unique product.

This works well. Starting with bigger models allows us to explore whats possible. I find it easier to scale down from here.

Built in Rust tells me a certain bar has been reached. Tells me the team went through a lot of effort to do their best. And the mature tooling makes it easy for me to evaluate and confirm my assumptions. So yes, positive marketing in my case.

In our game studio, engineers are creating lots of developer art on their own. But the real productivity booster is coming from artists using language models to generate entire art pipeline scripts. Several Python scripts to automate Blender3D and offline asset post-processing. Many artists are also changing shaders by asking language models to modify existing code.

Would it be possible to integrate something like bevy_engine as a plugin? For live or low-coding experience and tools.

You should consider surrounding yourself with people that can tell the story. It's common to not be able or willing to tell your own story. Others can carry or lift this weight for you, and take it where it needs to go.
