☕ Brewing Intelligence in Turkish: Introducing Kumru LLM

 At AIBrewLab, we believe every great innovation starts with a slow, mindful brew — and Kumru LLM is the freshest cup in the Turkish AI scene.

Developed entirely in Turkish from the ground up, Kumru marks a milestone for local AI development — a 7.4-billion-parameter language model trained with a native Turkish tokenizer, delivering up to 90% higher efficiency than multilingual counterparts.

Kumru isn’t just trained to know Turkish — it’s trained to feel the language’s rhythm, idioms, and subtle emotional undertones. With its lightweight architecture, it runs even on consumer-grade GPUs, opening the door for secure, compliant, and cost-efficient on-premise AI deployments across Türkiye.

🔬 Technical Excellence, Locally Engineered

Kumru is a decoder-only LLM trained from scratch for Turkish, though it also understands English and code. Built on Mistral-v3 architecture (equivalent to LLaMA-0.3 with the sliding window disabled), it inherits design choices from the LLaMA-3 technical paper, including optimizer and learning rate configurations.

Training lasted 45 days on H100/H200 GPUs, covering 500 GB of curated and deduplicated datasets and 300 billion tokens.

After pretraining, the model underwent fine-tuning on ~1 million mixed examples, enhancing its zero-shot capability across document summarization, question answering, and general instruction-following.

With a context window of 8,192 tokens (up to 20 A4 pages of text), Kumru is built to handle complex enterprise documents with remarkable efficiency.

⚙️ Light Yet Powerful

Thanks to its compact 7B design, Kumru runs comfortably on a 16 GB VRAM GPU (e.g., RTX A4000 or RTX 3090), making it ideal for on-premise deployment in sectors like finance and healthcare, where data sovereignty and Turkish compliance are essential.

Even compared to global giants like Gemma-3 27B (which requires a $30 000 GPU), Kumru achieves comparable performance for just a fraction of the cost (~$2 000 setup).

📊 Benchmark Results That Speak Turkish

In the Cetvel Benchmark — covering 26 NLP tasks including grammar correction, summarization, NLI, and text classification — both Kumru-7B and its smaller sibling Kumru-2B outperform significantly larger models such as LLaMA-3.3 70B, Gemma-3 27B, Qwen-2 72B, and Aya 32B.

Notably, Kumru excels in tasks requiring deep linguistic understanding of Turkish nuances, like grammar correction and abstractive summarization.

Internal evaluations further reveal that Kumru holds richer knowledge about Turkish culture, terminology, and geography compared to multilingual LLMs.

💡 Modern Turkish Tokenizer: Precision Meets Efficiency

Tokenizer design matters — and Kumru’s tokenizer is built natively for Turkish.

It integrates a custom RegEx pre-tokenizer that accurately handles newlines, punctuation, numerals, and tabs, while supporting multi-turn chat roles (system, user, assistant).

Compared with multilingual models, others use 38–98% more tokens to encode the same Turkish text — proving that Kumru’s tokenizer achieves higher semantic density, faster inference, and lower cost per token.

While its native context window is 8 192 tokens, its effective contextual representation rivals models with >16 k windows due to compact token efficiency.

🔧 Open-Source & Hugging Face Integration

Alongside Kumru-7B, the open-source Kumru-2B model is now available for experimentation on Hugging Face.

Despite its smaller size, it retains identical features — 8 192 token context, 300 B-token pretraining — and requires only 4.8 GB VRAM, making mobile or edge deployment feasible even without quantization.

During pretraining, the VNGRS team contributed upstream improvements to Hugging Face Transformers, resolving a batch-size bug in the FlashAttention packer implementation.

Their pull request is now merged into Transformers v4.47.0, marking Kumru’s technical footprint in the global open-source AI community.

☕ The AIBrew Take: A Fine Turkish Brew in the AI World

In the ever-expanding world of AI, Kumru stands as a symbol of local precision, linguistic authenticity, and accessible innovation.

For Turkey’s growing AI ecosystem, it’s not just a model — it’s a freshly brewed statement: that excellence can be local, open, and world-class.

A new blend of intelligence is brewing in Türkiye — and its name is Kumru LLM.
