Model Overview

RefinedNeuro/RN_TR_R2 is a Turkish‐language reasoning model fine-tuned from ytu-ce-cosmos/Turkish-Llama-8b-DPO-v0.1 using the GRPO method on distilled Q&A data of Qwen3 model. It excels at open-ended reasoning tasks in Turkish, particularly STEM, history, and cultural questions.

Evaluation

Benchmark: RN_TR_R2_Benchmark_Results (Open-ended Turkish culture & reasoning questions)

Model Name	Score (%)	Description
RefinedNeuro/RN_TR_R2	82.4	Upgraded from RN_TR_R1 via GRPO on distilled Qwen3 data
Qwen3-8B	76.8	Off-the-shelf Qwen3-8B
RefinedNeuro/RN_TR_R1	64.8	Baseline Turkish-fine-tuned model
ytu-ce-cosmos/Turkish-Llama-8b-DPO-v0.1	63.2	Turkish-adapted Llama-8B via direct preference optimization
Meta-Llama-3.1-8B-Instruct	63.2	Meta’s Llama-3.1-8B with instruct tuning

RN_TR_R2 achieves a 17.6 pp improvement over the RN_TR_R1 baseline.

Intended Use

Primary use cases: Question answering, step-by-step reasoning, educational tools in Turkish (math, physics, chemistry, biology, geometry, trigonometry, statistics, history, culture).
Not recommended: Generating creative fiction or tasks requiring memorized facts outside its training scope.
Known limitations: While no systematic failure modes are identified, RN_TR_R2 may hallucinate like all LLMs.

Sample Q&A

> **Q:** f(x) = 3x⁴ - 2x³ + 5x - 7 fonksiyonunun x = 1 noktasındaki türevini bulunuz.
>
> **A:** <think>

1. Adım: f(x) = 3x⁴ - 2x³ + 5x - 7 fonksiyonunun türevini bulmak için, önce f(x)'nin türevini bulmamız gerekmektedir.

2. Adım: Türevi bulmak için fonksiyonu parçalara ayırarak analiz edeceğiz.

f(x) = 3x⁴ - 2x³ + 5x - 7

3. Adım: Türevi bulmak için her terimi ayrı ayrı türevini buluyoruz.

- 3x⁴: Türevi 12x³'dür.
- -2x³: Türevi -6x²'dir.
- 5x: Türevi 5'dir.
- -7: Türevi 0'dır (çünkü sabit bir sayıdır).

4. Adım: Türevi bulmak için elde edilen türevleri birleştiriyoruz.

f'(x) = 12x³ - 6x² + 5

5. Adım: Şimdi x = 1 yerine koyarak f'(x)'nin türevini hesaplayacağız.

f'(1) = 12(1)³ - 6(1)² + 5

f'(1) = 12(1) - 6(1) + 5

f'(1) = 12 - 6 + 5

f'(1) = 11

6. Adım: x = 1 noktasındaki türevi 11 olarak bulduk.

\boxed{11}

</think>

\boxed{11}
