LoRA fine-tune of unsloth/DeepSeek-R1-0528-Qwen3-8B for German Mathematical Reasoning

This repository contains LoRA adapters for the unsloth/DeepSeek-R1-0528-Qwen3-8B model, fine-tuned on the open-r1/DAPO-Math-17k-Processed dataset for German mathematical reasoning tasks.

This model was trained using the GRPO (Group Relative Policy Optimization) algorithm.

How to use

To use these LoRA adapters, load the base model from this repository.

from unsloth import FastLanguageModel
import torch

model, tokenizer = FastLanguageModel.from_pretrained(
    model_name = "jquad/DeepSeek-R1-0528-Qwen3-8B-German-GRPO", # LoRA adapters are loaded automatically
    max_seq_length = 1024,
    dtype = None,
    load_in_4bit = True,
)

# Example prompt
prompt = "Was ist 2 + 2?"
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=20)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Intended Use

This model is intended for mathematical reasoning in German. It has been fine-tuned on a specialized dataset and may not be suitable for general-purpose tasks.

This is a research artifact and should not be used in production without further evaluation.
