Turkish-LLM-32B-Instruct

The largest open-source Turkish-enhanced language model. Fine-tuned from Qwen2.5-32B-Instruct with QLoRA on a carefully curated 173K Turkish instruction dataset.

Part of the Turkish LLM Family - a complete suite of Turkish language models from 7B to 32B.

Highlights

32B parameters - largest openly available Turkish fine-tuned model
Outperforms base model on MMLU-TR (+2.71) and XCOPA-TR (+1.00)
67.89% MMLU-TR - significant improvement through iterative dataset engineering
GGUF available - Q4/Q5/Q8 quantizations for local inference

Benchmark Results

Benchmark	Base (Qwen2.5-32B)	v1 (Mar 21)	v2 (Current)	Delta vs Base
MMLU-TR (57 categories)	0.6518	0.6564	0.6789	+2.71
XCOPA-TR (Causal Reasoning)	0.6800	0.6740	0.6900	+1.00
XNLI-TR (NLI)	0.4578	0.4610	0.4514	-0.64

Iterative Improvement

This model is the result of systematic dataset engineering across multiple iterations:

v1 (Mar 21): Initial fine-tune with 242K examples. Improved MMLU-TR and XNLI-TR but regressed on XCOPA-TR.
v2 (Mar 29): Rebalanced dataset (173K examples) with XCOPA augmentation and evaluation-aligned NLI formatting. Achieved improvements on both MMLU-TR and XCOPA-TR.

Key insight: reducing dataset size from 242K to 173K while improving data quality led to better results — quality over quantity.

Quick Start

With Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "ogulcanaydogan/Turkish-LLM-32B-Instruct",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("ogulcanaydogan/Turkish-LLM-32B-Instruct")

messages = [
    {"role": "system", "content": "Sen yardimci bir Turkce asistansin."},
    {"role": "user", "content": "Yapay zekanin saglik sektorundeki uygulamalarini acikla."}
]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer([text], return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
