AI Chatbot in Minecraft!

[tranquil bay]

I’ve been working on a Fabric mod called NotchNet. It lets you ask questions in chat and get AI-powered answers while you play! Just type:

/notchnet <question>
The AI responds asynchronously, so it won’t interrupt your game. It’s lightweight and meant to be fun—a little tool to make your world more interactive.

I’d love for you to try it and tell me what you think. Any feedback, suggestions, or funny AI responses are welcome!

Coming soon:

Mod compatibility—ask NotchNet about mods installed in your client.

Server version

P.S. I’m looking for someone experienced to help host a Discord server for the mod. Full access and control provided—DM me if interested!

@late haven why 7A?

[late haven]

7 is the no advertisement rule (looking for people to run your discord) and that's AI

[tranquil bay]

wdym thats ai

[pure kayak]

It’s an ai chatbot mod so yeah ig it’s ai

[tranquil bay]

so is it not allowed here or smthn?

[pure kayak]

it should be okay

[reef sable]

so is this local ai or nah?

and is it rate limited?

[tranquil bay]

no its hosted and its my own custom ai

[tranquil bay]

yes, but you probably won't be able to make that many requests inside minecraft that quickly anyway

[reef sable]

cool, how are you running it

[tranquil bay]

cloud hosting

[reef sable]

well obviously, but like from where? aws?

[tranquil bay]

cant share that for security reasons sorry

[reef sable]

does it cost money for me to use the mod?

[scarlet condor]

dont think so

[reef sable]

well cloud hosting isn’t free, so gotta ask

[tranquil bay]

no its free

[tranquil bay]

i want to bring it servers too, so hopefully i can monetise it through servers

[slow inlet]

your mod is hella insecure (coming from a cyber security guy)

💀

[slow inlet]

google cloud (probably using the 300$ credits)

[tranquil bay]

im still working on security, im quite new to minecraft modding, so security wise its harder to implement

at least harder for me

[slow inlet]

it's not really related to modded minecraft when we are talking about security

but you can do what i told you in dms and obfuscate your code to hide the decryption logic

💀

[silent zealot]

🔺

[reef sable]

ain’t nothing gonna save you from droppin the api key in the jar tho, obfuscation or not

[slow inlet]

he can actually hide it in a way where nobody would find it lmao

[reef sable]

i doubt that would prevent a competent attacker tho

obfuscation is not really designed for secrets

[slow inlet]

yeah

i'm pretty experienced and whatever he does is crackable

but most people are stupid

[reef sable]

fair, but it’s the competent people you need to worry about

[slow inlet]

true

what's the point of the api key anyways

keep it open and check the origin server side

but same issue

as long as we have some client side validation there's no way of protecting it

[reef sable]

there isnt, i just assume he might use one if he is cloud hosting with a platform that requires one

but i dont know why you would want to willingly let other people use your cloud hosting service for free

[slow inlet]

i swear

he's on google cloud

using the 300 dollar credits

[reef sable]

yeah, but its still not free for more than those given credits to host

and with other people using the mod, it will run out pretty fast

[slow inlet]

indeed

i burned that 300$ in a week of using Gemini

[tranquil bay]

im using my own custom ai so its different

[tranquil bay]

for the people downvoting it, i'm doing major reworks to the backend, so it wont work for a few days

[slow inlet]

i figured that

[reef sable]

just curious

why did you use your own custom llm?

[tranquil bay]

its not exactly custom

but it uses text embeddings, based on the entire minecraft wiki

thats really the custom part

the llm's job is to just produce the answer

the text embedding is essentially the brains

[reef sable]

oh so does it vector search the minecraft wiki and feed the result to the llm?

[tranquil bay]

its a little bit more complicated

so first you use a text embedding model to compile the model into a faiis index, which is somethiing the llm can understand

then you give the faiss index to the llm, with will use it as the brains, and will output the rest as an llm generated message, just the thought process has gone through the faiss index

[coral ivy]

Long story short: you're giving your copy of the LLM new information that it can use.

[reef sable]

so yes

[tranquil bay]

and its complicated for some reason

[reef sable]

thats just a pretty typical rag system with a vector search, not really that complicated

only way it would get simpler is if you loaded all the vectors into a matrix and did a matrix multiplication with an argmax to find the best match, but that's never really done (unless the vector database is quite small)

[tranquil bay]

do you mean more complicated?

because ive never seen that methods before so im just curious

[reef sable]

no, that method is DEFINITELY simpler

faiss indices are a big step up from having no index

the faiss indexing is just abstracted because you (probably) use a library for it, so you dont know whats going on behind the scenes

[tranquil bay]

so your talking about faiss index

thats what i use

[tranquil bay]

..

[reef sable]

with faiss indexing, you dont compute cos sims for every vector entry, with that other method, you do

[reef sable]

yeah, but theres a lot that goes into that (like generating the index to begin with)

[tranquil bay]

ohh i see what you're talking about now

[reef sable]

yeah
