# Kona2-12B-Instruct

**Kona2-12B-Instruct** is a 12-billion parameter instruction-tuned language model for Georgian and English. Built on [Kona2-12B-Base](https://huggingface.co/tbilisi-ai-lab/kona2-12B-Base) through supervised fine-tuning (SFT), it excels at chat, question answering, and function calling.

## Model Summary

| Property | Value |
|----------|-------|
| Parameters | 12B |
| Architecture | Mistral (Transformer) |
| Context Length | 32K tokens |
| Languages | Georgian (ka), English (en), other (limited) |
| Training | Supervised Fine-Tuning (SFT) |
| Training Examples | ~2.8M instructions |
| Function Calling | Yes (Hermes format) |
| Base Model | [kona2-12B-Base](https://huggingface.co/tbilisi-ai-lab/kona2-12B-Base) |

## Intended Uses

### Primary Use Cases
- Conversational AI assistants (Georgian/English)
- Question answering and information retrieval
- Function/tool calling applications
- **Translation between Georgian and English** (especially strong)
- Code generation and explanation
- Educational and tutoring applications

## Training

## Usage

### Installation

```bash
pip install transformers torch accelerate
```

### Chat Completion

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

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

messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "რა არის საქართველოს დედაქალაქი?"}
]

inputs = tokenizer.apply_chat_template(
    messages, 
    return_tensors="pt",
    add_generation_prompt=True
).to(model.device)

outputs = model.generate(inputs, max_new_tokens=256, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

### Function Calling (Hermes Format)

See the tokenizer's jinja template (`tokenizer_config.json`) for details on how function calling is formatted.

```python
tools = [
    {
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Get current weather for a location",
            "parameters": {
                "type": "object",
                "properties": {
                    "location": {"type": "string", "description": "City name"}
                },
                "required": ["location"]
            }
        }
    }
]

messages = [
    {"role": "system", "content": "You are a helpful assistant with access to tools."},
    {"role": "user", "content": "What's the weather in Tbilisi?"}
]

inputs = tokenizer.apply_chat_template(
    messages,
    tools=tools,
    return_tensors="pt",
    add_generation_prompt=True
).to(model.device)

outputs = model.generate(inputs, max_new_tokens=256)
# Output will include <tool_call>{"name": "get_weather", "arguments": {"location": "Tbilisi"}}</tool_call>
```
