*Equal contribution

In Arabic, حلا (Hala) conveys sweetness and beauty—qualities long associated with the language itself. In this spirit, we call our models Hala.

Example

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

model_id = "hammh0a/Hala-9B"  # pick a released Hala model

tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id, torch_dtype="auto", device_map="auto"
)

# Use chat template
messages = [
    {"role": "system", "content": "أنت مساعد خبير في الفيزياء."},
    {"role": "user", "content": "اشرح بإيجاز مبدأ الانحفاظ في الفيزياء، وأعطني مثالاً يومياً."},
]

prompt = tok.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)

pipe = pipeline("text-generation", model=model, tokenizer=tok)
out = pipe(prompt, max_new_tokens=256, do_sample=False)

print(out[0]["generated_text"])
