Kona2-12B-Base

Kona2-12B-Base is a 12-billion parameter base language model optimized for Georgian language understanding and generation. It is built by continue-pretraining Mistral-Nemo-Base-2407 on approximately 30 billion tokens of Georgian/English data with expanded Georgian vocabulary.

Model Summary

Property	Value
Parameters	12B
Architecture	Mistral (Transformer)
Context Length	8K tokens
Vocabulary	Extended (~20K Georgian tokens)
Languages	Georgian (ka), English (en), other (limited)
Training Tokens	~30B
Training	Continue pre-training (embeddings + high-rank LoRA)
Base Model	mistralai/Mistral-Nemo-Base-2407

Intended Uses

Primary Use Cases

Base model for Georgian language fine-tuning
Georgian text generation and completion
Multilingual text understanding (KA/EN primary, others limited)
Foundation for instruction-tuned models
Translation capabilities (enhanced in fine-tuned versions)

Training

Training Data (~30B Tokens)

Open source corpora
Web content (custom crawlers/scrapers)
Translated texts

Vocabulary Expansion

Added ~20K Georgian tokens to improve tokenization efficiency:

Tokenizer fertility: 1.9 tokens/word on Georgian text
New embeddings initialized as mean of subtoken embeddings

Training Procedure

Method: Continue pre-training
Embeddings: Full training (unfrozen)
LoRA: High-rank adaptation on transformer layers
Training Context: 8K tokens
Precision: BF16
Infrastructure: NVIDIA H100 GPUs

Usage

Installation

pip install transformers torch accelerate

Basic Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "tbilisi-ai-lab/kona2-12B-Base",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("tbilisi-ai-lab/kona2-12B-Base")

# Text completion
text = "საქართველო არის"
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
