# Oolel: A High-Performing Open LLM for Wolof

<video controls autoplay src="https://cdn-uploads.huggingface.co/production/uploads/62e335bbf15e7fce909fe5d4/liiZ1rAkiIgGpgN_jqwq6.mp4"></video>


Despite numerous open-source innovations in large language models, African languages have remained underrepresented.

**Soynade Research** is transforming this landscape with Oolel, the first open-source language model for Wolof.

Built on the **Qwen 2.5** architecture, Oolel combines state-of-the-art AI technology with deep Wolof linguistic expertise. With careful high-quality curated data, we trained and optimized Oolel for the following tasks:

- **RAG** supporting Wolof queries with English, French, or Wolof context.
- **Bidirectional translation between English and Wolof**
- **Natural text generation in Wolof**
- **Math in Wolof**
- **And many other standard NLP tasks**:
    - Summarization
    - Text edition
    - etc

## 3. Usage

**!!! It's important to add your system prompt !!!**

Here provides a code snippet with apply_chat_template to show you how to load the tokenizer and model and how to generate contents.
```python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

device = "cuda" 

model = AutoModelForCausalLM.from_pretrained(
    "soynade-research/Oolel-v0.1",
    torch_dtype = torch.bfloat16,
    device_map="auto")

tokenizer = AutoTokenizer.from_pretrained("soynade-research/Oolel-v0.1")

def generate_response(messages, max_new_tokens=1024, temperature=0.1):
    text = tokenizer.apply_chat_template(
          messages,
          tokenize=False,
          add_generation_prompt=True
)
    model_inputs = tokenizer([text], return_tensors="pt").to(device)
    generated_ids = model.generate(model_inputs.input_ids, max_new_tokens=max_new_tokens, temperature=temperature)
    
    generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)]
    response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
    return response

```


**Some tasks examples:**

1. **Translation Tasks**

```python
system_prompt = "You're a Wolof AI assistant. Please always provide detailed and useful answers to the user queries."
messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": "Translate to Wolof: Bassirou Diomaye Faye is the new Senegalese president. He is 44 years old"}
]
print(generate_response(messages))
```

2. **Code generation**

```python
system_prompt = "You're a Wolof AI assistant. Please always provide detailed and useful answers to the user queries"
messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": "Bindal ab klaas Python buy wone ni ñuy jëfandikoo dataframe yi ci Pandas"}
]
print(generate_response(messages))
```

3. **Problem Solving**

```python
system_prompt = "You're a Wolof AI assistant. Please always provide detailed and useful answers to the user queries."
messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": "Ndax nga mën ma won ni ñuy resolver problème bii: Fatou dafa jënd 3 kilo ceeb, 2 kilo diw ak 5 kilo sukër. Ceeb gi wenn kilo 500 CFA la, diw gi 1200 CFA kilo bi, sukër gi 750 CFA kilo bi. Ñaata la wara fay?"}
]
from pprint import pprint
pprint(generate_response(messages))
```

  
4.  **Text Generation** (e.g. story generation)

```python
system_prompt = "You are a skilled Wolof storyteller (Gewël) with deep knowledge of African folktales and traditions. Write engaging stories in Wolof that reflect African cultural values and wisdom."
messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": "Bindal ab léeb ci gaynde gi lekk muus mi"}
]
print(generate_response(messages, temperature=0.9))
```

5. **Multi-turn conversations**
Oolel is not optimized for multi-turn conversations, but you can try it!
```bash
messages = [
   {"role": "user", "content": "Wax ma clan mooy CEDEAO ? Ci lan la liggeey?"},
   {"role": "assistant", "content": "CEDEAO mooy 'organisation' gu boole reew yi nekk ci pennc Afrika bi. Mu ngi sukkandiku ci wàll économie, politig, ak déggoo diggante reew yi"},
   {"role": "user", "content": "ñaata reew ñoo ci bokk?"}
]
print(generate_response(messages))
```
