# Abegi-Llama3

## Model Card Summary

**Abegi-Llama3** is a Bangla-focused large language model fine-tuned from **Meta LLaMA‑3.1‑8B‑Instruct**. The model is optimized for Bangla (bn) conversational text generation and instruction-following tasks, while retaining general-purpose reasoning and generation capabilities inherited from the base model.

---

## Model Details

### Model Description

Abegi-Llama3 is a decoder-only Transformer-based causal language model fine-tuned to improve naturalness, fluency, and instruction-following behavior in Bangla. It is suitable for chat-style interactions, content generation, and educational or research use cases involving the Bangla language.

* **Developed by:** Promit123546
* **Model type:** Causal Language Model (Decoder-only Transformer)
* **Base model:** meta-llama/Llama-3.1-8B-Instruct
* **Language(s):** Bangla (bn), with partial English support inherited from the base model
* **License:** LLaMA 3 License (inherited from base model)
* **Fine-tuned from:** meta-llama/Llama-3.1-8B-Instruct

## Uses

### Direct Use

The model can be used directly for:

* Bangla conversational agents and chatbots
* Bangla text generation and rewriting
* Question answering in Bangla
* Educational and experimental NLP applications

### Downstream Use

With further fine-tuning, the model can be adapted for:

* Domain-specific Bangla assistants (education, customer support, documentation)
* Bangla instruction-following systems
* Research on low-resource or regional language modeling

### Out-of-Scope Use

The model is **not recommended** for:

* Medical, legal, or financial decision-making
* High-stakes or safety-critical systems
* Generating harmful, misleading, or malicious content

---

## Bias, Risks, and Limitations

* The model may reflect biases present in the training and fine-tuning data
* It can produce hallucinated or incorrect information
* Performance may degrade for tasks outside Bangla or conversational generation
* Cultural or linguistic nuances may not always be handled perfectly

### Recommendations

* Verify critical outputs using trusted external sources
* Apply moderation and safety filters in production environments
* Avoid use in sensitive or high-risk applications without human oversight

## How to Get Started with the Model

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

model_id = "Promit123546/Abegi-Llama3"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

prompt = "বাংলায় কৃত্রিম বুদ্ধিমত্তা কী?"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=150)

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