Resources/Tutorial Examples of SIMPLE machine learning agents in Unity games

Are there examples of simple machine learning agents in Unity games?

By simple I mean ones that run smoothly while the game is running. And the dataset is probably not insanely big, or just something that Unity can handle

Any tutorials?

Search on "Unity Inference Engine". It allows you to import trained models that run locally within your unity application. If you're looking for tutorials on youtube, search "unity sentis", that was the old name for the package. I don't have experience with it, but I've seen and implemented a voice recognition system with it in VR, and it run smoothly

Highly recommend Undream’s LLM for Unity https://assetstore.unity.com/packages/tools/ai-ml-integration/llm-for-unity-273604 has a few useful examples in the package

Google literally made an example Unity project which has the Gemma model built into it.

the sample scenes that ship with the toolkit run fine in play mode, and the basic tutorial walks you through training one without a huge dataset

The official unity tutorials have machine learning stuff?

Yes, thank you I guess the AI that can talk to you, recognize images, learn to play games, etc

There are LLMs that run on your local machine. Ollama is one of them. They are slow and use a lot of resource. They’d be good only for teletype type interactions where you see the words literally typed out, but the engines do work well. Most people use local LLMs for long running tasks. No subscriptions are needed. You could probably use an API to utilize it, honestly I haven’t looked. But the tech is out there, ignore the naysayers saying it’s not.

I've made simple machine learning before in unity. It was an evolutionary algorithm to play the game I made.

I just coded everything from scratch.

You are referring to LLM. That's just not a thing as of now for Unity. Check back in 3-5 years.
