Luma-base: A High-Performance Foundation Model for Haitian Creole (Kreyòl Ayisyen)

Luma-base is a state-of-the-art 4-billion parameter language model, specialized in Haitian Creole. Based on the Qwen3-4B architecture, it has undergone extensive domain-specific pre-training to capture the nuances, grammar, and cultural context of the Haitian language.

🚀 Project Overview

The Luma project aims to bridge the gap in high-quality AI tools for Haitian Creole. Luma-base is the core engine designed to serve as a backbone for STT (Speech-to-Text) correction, translation, and text generation.

• Developer: Frostie08
• Model Type: Causal Language Model

🛠️ Implementation & Usage

1. For Direct Inference (Text Completion)

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "Frostie08/Luma-base"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Example: Historical/Biblical context completion
text = "Nan konmansman, Bondye te kreye..."
inputs = tokenizer(text, return_tensors="pt").to("cuda")

with torch.no_grad():
    outputs = model.generate(**inputs, max_new_tokens=100, temperature=0.6)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
