Llama 3 8 billion model was finetuned using unsloth package on a cleaned Bangla alpaca dataset. After that the model was quantized in 4-bit. The model is finetuned for 2 epoch on a single T4 GPU.

Pros & Cons of the Model

Pros

The model can comprehend the Bangla language, including its semantic nuances
Given context model can answer the question based on the context

Cons

Model is unable to do creative or complex work. i.e: creating a poem or solving a math problem in Bangla
Since the size of the dataset was small, the model lacks lot of general knowledge in Bangla

Run The Model

FastLanguageModel from unsloth for 2x faster inference

python

from unsloth import FastLanguageModel
model, tokenizer = FastLanguageModel.from_pretrained(
    model_name = "KillerShoaib/llama-3-8b-bangla-4bit",
    max_seq_length = 2048,
    dtype = None,
    load_in_4bit = True,
)
FastLanguageModel.for_inference(model)

# alpaca_prompt for the model
alpaca_prompt = """Below is an instruction in bangla that describes a task, paired with an input also in bangla that provides further context. Write a response in bangla that appropriately completes the request.

### Instruction:
{}

### Input:
{}

### Response:
{}"""

# input with instruction and input
inputs = tokenizer(
[
    alpaca_prompt.format(
        "সুস্থ থাকার তিনটি উপায় বলুন", # instruction
        "", # input
        "", # output - leave this blank for generation!
    )
], return_tensors = "pt").to("cuda")

# generating the output and decoding it
outputs = model.generate(**inputs, max_new_tokens = 2048, use_cache = True)
tokenizer.batch_decode(outputs)

AutoModelForCausalLM from Hugginface
