# Karnak: Enhanced Arabic–English Large Language Model
## Model Summary
**Karnak** is a depth-extended causal language model optimized for **Arabic and English** generation. It is built on top of **Qwen/Qwen3-30B-A3B-Instruct-2507**, featuring architectural depth extension and a tokenizer specifically optimized for Arabic to improve fluency and efficiency.
Karnak was trained using **high-quality, filtered data** through a rigorous pipeline to enhance overall instruction-following capabilities, factuality, and robustness.
## Key Features
- **Depth Extension (~40B):** Expanded depth to increase reasoning capacity and improve long-range dependency modeling.
- **Arabic-Optimized Tokenizer:** Improved Arabic tokenization efficiency, resulting in reduced token fragmentation and higher-quality generation.
- **Multi-Stage Training:** The model evolved through: Pre-trained weights → Depth Extension → Continued Pre-training → SFT (Supervised Fine-Tuning).
- **Extended Context Window:** Designed for long-context usage with a **safe context range up to 20K tokens** (recommended to stay within this limit for optimal stability).
## Model Details
- **Model Name:** Karnak
- **Base Model:** Qwen/Qwen3-30B-A3B-Instruct-2507
- **Parameter Count:** ~40B (Depth-Extended)
- **Languages:** Arabic, English
- **Training:** High-quality filtered data + Multi-stage pipeline (Continued pre-training + SFT)
- **Safe Context Range:** Up to **20,000 tokens**

## Usage
### 1) Hugging Face Transformers
To use Karnak with the standard Transformers library, ensure you have the latest version installed.
```bash
pip install -U "transformers>=4.40.0" torch accelerate
```
Python Code Example (Chat Template):
```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "Applied-Innovation-Center/Karnak"
# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
model_id,
device_map="auto",
torch_dtype=torch.bfloat16,
trust_remote_code=True,
)
# Prepare Input
prompt = "اشرح لي نظرية النسبية بشكل مبسط."
messages = [
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": prompt},
]
# Apply chat template
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
# Generate
generated_ids = model.generate(
**model_inputs,
max_new_tokens=512,
temperature=0.7,
top_p=0.9,
)
# Decode output (removing the prompt tokens)
generated_ids = generated_ids[:, model_inputs.input_ids.shape[1]:]
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
```
2) vLLM (Recommended for Production)
Karnak is compatible with vLLM for high-throughput inference.
Installation:
```bash
pip install -U vllm
```
Offline Inference:
```python
from vllm import LLM, SamplingParams
model_id = "Applied-Innovation-Center/Karnak"
# Initialize the model
llm = LLM(
model=model_id,
trust_remote_code=True,
max_model_len=20000, # Safe context range
tensor_parallel_size=1, # Adjust based on available GPUs
)
# Set sampling parameters
sampling_params = SamplingParams(
temperature=0.7,
top_p=0.9,
max_tokens=512,
)
# Generate
prompts = ["ما هي عاصمة مصر؟"]
outputs = llm.generate(prompts, sampling_params)
for o in outputs:
print(f"Prompt: {o.prompt}")
print(f"Generated: {o.outputs[0].text}")
```
Server Mode (OpenAI-Compatible API):
You can serve the model as an API compatible with OpenAI clients:
```bash
vllm serve "Applied-Innovation-Center/Karnak" \
--trust-remote-code \
--dtype bfloat16 \
--port 8000
```
