Qwen3-4B-TL-JSON

Let me start by saying this is a test, not an attempt to make the best LLM ever at 4B, as much as i'd like to.

This is V0.2 of finetuning Qwen3-4B with line by line translations in json format with variable line amounts per example. With the goal of improving its ability to handle this format.

Finetuned for 5168 examples, plan to expand to 30000 examples and a larger rank, while reducing the learning rate, and I also plan on using examples of the shisa v2 dataset to finetune its japanese understanding at some point,

In personal testing with this particular build.

I recommend using temperature 0.3, and then the normal sampler params for this model

When benchmarking how 'accurate' it is to maintaining this format, i got greater than 95% success when json parsing 512 samples generated from this model.
