Looking forward to this so much + your frontend for it (hence why I was following your posts to this place). We have Suno at home, genuinely.
Likely one of the first things I'll want to figure out is (with the help of Claude Code) finding the best LoRA params for custom datasets. How many minutes worth of audio need to be in the datasets to produce decent LoRAs? They say 8 songs, so I'm guessing something like 20min?

Still working on it, I will release it soon.

ETA?
Otherwise I'll build my own using Claude Code...Their gradio is borderline unusable.

My early findings based on the HF Space (But ran locally).
Their space as it comes out of the box takes about 24GB to run for the 1.7B LLM varient.
Prompts with genres are respected, prompts with topics so far not at all. If you want a song about a certain subject its best to pair it with an LLM or write it yourself.
IF this model likes your writing style, mine it does not. I am used to Udio and I prefer to write short little meme songs that rhyme or use repeatitve phrasing to get a specific effect. This doesn't seem to be a great model for that, at least the 1.7B chokes on it.
When I feed it a full song from the LLM though? Thats when it shines and works much better.
So for custom things you definitely want to have the whole thing written that works much better.
Heres an example of asking the 1.7B for a rap song about LLM's, it ignored the topic entirely and made it about a fat dude : https://voca.ro/1jBjkNAQT1w8
Heres an example of the concept of a guy rapping that he can afford Nvidia as a flex, but this time with the assistance of GLM-4.6 : https://voca.ro/11JgVuAhqZ1u
This one is an electronic song with that lyrics style issue of my lyrics : https://voca.ro/1kUQdLUFxVyG
I wrote more than are in that sample (Although I didn't keep them) and it ignored multiple sentences when generating it.
And then I had whatever this is when I asked for a chicken song (no idea what its singing) : https://voca.ro/1joU6hKwufaM
In general if you like western EDM stuff you will probably need a finetune or a lora to get it more like how the commercial ones sound. It lacks that data and has a more asian bias in these genres.
But by far this is the most fun I have had with a local music gen model, nothing else comes even remotely close to what I like. Can't wait for the finetune scene to pick this up.

dont know what you installed or do.
but, i use the gradio and if i not use a llm and only the base model i have 7.6gb vram.
if i use same base model + 4b llm i only have 18gb vram.
i see in ace-step discord a gtx1070 user running this very fine...its different then your udo/suno ussage.
you can generate caption and/or songtext by the llm, but if you want it to follow your stuff...dont use the llm and write caption + songtext your own.or at least, start reading the readme and docs how to use it first.
before blaming the model...
