What is it?

This is my further improvement of my previous gemma 3 4b it finetune, trained on way bigger amounts of unique data(17M tokens), which resulted in way better writing, bringing the model closer to how 8b and even 12b models write, at times.

Details:

Advantages:

Way better writing than the base model, less slop and enhanced creativity
keeps good track of the story
Small, runs fast
Better understanding of complex emotional topics

Disadvantages:

4b model has limited logic, this tune forces all of this logic to work in order to provide the best creative writing possible

A word on the quants for this model:

BF16- Mostly overkill, however, highest quality
Q8_0- Amazing quality, near lossless
Q6_K- High quality, fast
Q5_K_M- Mid to high quality, small and fast
Q4_K_M- Mid quality, very small and very fast

Quants are located in the repo, along with safetensors

What I will do next and is v3 possible?

Next I will probably turn my attention back to smaller models, like Qwen 3.5 2b and LFM 1.2b. I also may train a new version on an even bigger dataset, but it might result in overfitting, overall, this model is the peak performance for a 4b model, or at least the best I could do. working with it wasnt easy, but I did my best and feel satisfied with the results.

PS:(Honestly, I wasted too much time on that, there will soon be a WN9 in Limbus so I probably will finetune less)
