Libraries

How to use smshahbaj/Rifa-Nano-0.5B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(

RIFA Nano (0.5B)

The smallest model in the RIFA series
Fine-tuned by SM Shahbaj

About

RIFA Nano is a carefully fine-tuned version of Qwen/Qwen2.5-0.5B-Instruct.
It is designed to be a lightweight, helpful assistant with strong Bangla support and reduced hallucination on unanswerable questions.

Property	Value
Name	RIFA Nano
Parameters	0.5B
Base Model	Qwen/Qwen2.5-0.5B-Instruct
Fine-tuned by	SM Shahbaj
Series	RIFA (Nano → Flash → Code → Edge → Pro)

What's new in v2

Improved skill mix (Bangla + English + coding + light math + general knowledge)
Dedicated anti-hallucination training ("I don't know" examples)
Full-precision LoRA (no 4-bit quantization)
Two-stage training: capability first → identity anchoring
Lower LoRA rank + conservative data volume to avoid capability degradation at 0.5B scale

Quick Start

Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

repo = "smshahbaj/Rifa-Nano-0.5B"
tokenizer = AutoTokenizer.from_pretrained(repo)
model = AutoModelForCausalLM.from_pretrained(repo, device_map="auto")

messages = [{"role": "user", "content": "তুমি কে?"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=128)
print(tokenizer.decode(out[0], skip_special_tokens=True))

GGUF (LM Studio / Ollama / llama.cpp)

Download any .gguf file from the table above and load it directly.

Limitations

This is a 0.5B model. It will still make mistakes on complex reasoning, very recent events, and obscure facts.
The anti-hallucination training reduces confident wrong answers on clearly unanswerable questions, but it does not add knowledge beyond the model's size.
Always double-check important information (code, numbers, facts).
