Nemotron-4-Mini-Hindi-4B-Instruct is a model for generating responses to questions grounded in the Indian context. It supports queries in Hindi, English, and Hinglish. It is a small language model (SLM) which is fine-tuned/aligned version of nvidia/Nemotron-4-Mini-Hindi-4B-Base, which was continuously pre-trained on top of Nemotron-Mini-4B-Base (Minitron-4B-Base). The alignment stage uses a mix of real and synthetically generated alignment corpus. It supports a context length of 4,096 tokens. This model is ready for commercial use.
Please refer to our arXiv paper for more details.
Nemotron-4-Mini-Hindi-4B-Instruct uses a model embedding size of 3072, 32 attention heads, and an MLP intermediate dimension of 9216. It also uses Grouped-Query Attention (GQA) and Rotary Position Embeddings (RoPE).
Architecture Type: Transformer Decoder (auto-regressive language model)
Network Architecture: Nemotron-4
Prompt Format:
We recommend using the following prompt template, which was used to fine-tune the model. The model may not perform optimally without it.
Note that a newline character \n should be added at the end of the prompt.
We recommend using <extra_id_1> as a stop token.
Usage
from transformers import AutoTokenizer, AutoModelForCausalLM
# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("nvidia/Nemotron-4-Mini-Hindi-4B-Instruct")
model = AutoModelForCausalLM.from_pretrained("nvidia/Nemotron-4-Mini-Hindi-4B-Instruct")
# Use the prompt template
messages = [
{"role": "user", "content": "भारत की संस्कृति के बारे में बताएं।"},
]
tokenized_chat = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt")
outputs = model.generate(tokenized_chat, max_new_tokens=128)
print(tokenizer.decode(outputs[0]))
You can also use pipeline but you need to create a tokenizer object and assign it to the pipeline manually.
from transformers import AutoTokenizer
from transformers import pipeline
tokenizer = AutoTokenizer.from_pretrained("nvidia/Nemotron-4-Mini-Hindi-4B-Instruct")
messages = [
{"role": "user", "content": "भारत की संस्कृति के बारे में बताएं।"},
]
pipe = pipeline("text-generation", model="nvidia/Nemotron-4-Mini-Hindi-4B-Instruct", max_new_tokens=128)
pipe.tokenizer = tokenizer # You need to assign tokenizer manually
pipe(messages)

DType: Float16/BFloat16
AI Safety Efforts
The Nemotron-4-Mini-Hindi-4B-Instruct model underwent AI safety evaluation including adversarial testing via three distinct methods:
Garak, is an automated LLM vulnerability scanner that probes for common weaknesses, including prompt injection and data leakage.
AEGIS, is a content safety evaluation dataset and LLM based content safety classifier model, that adheres to a broad taxonomy of 13 categories of critical risks in human-LLM interactions.
Human Content Red Teaming leveraging human interaction and evaluation of the models' responses.
Limitations
The model was trained on data that contains toxic language and societal biases originally crawled from the internet. Therefore, the model may amplify those biases and return toxic responses especially when prompted with toxic prompts. The model may generate answers that may be inaccurate, omit key information, or include irrelevant or redundant text producing socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive. The model may answer with I statements, exhibiting some anthropomorphizing. This issue could be exacerbated without the use of the recommended prompt template.
Ethical Considerations
NVIDIA believes Trustworthy AI is a shared responsibility and we have established policies and practices to enable development for a wide array of AI applications. When downloaded or used in accordance with our terms of service, developers should work with their internal model team to ensure this model meets requirements for the relevant industry and use case and addresses unforeseen product misuse.
