Inference

Running the model on a GPU using different precisions

• Using torch.float16

# pip install accelerate
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("saidines12/telugu-news-headline-generation")
model = AutoModelForCausalLM.from_pretrained("saidines12/telugu-news-headline-generation", device_map="auto", revision="float16")

input_text = "Generate relevant, interesting, factual short headline from this news article in telugu language\n <Your Telugu news article text here>"
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")

outputs = model.generate(**input_ids)
print(tokenizer.decode(outputs[0]))

• Using torch.bfloat16

# pip install accelerate
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("saidines12/telugu-news-headline-generation")
model = AutoModelForCausalLM.from_pretrained("saidines12/telugu-news-headline-generation", device_map="auto", torch_dtype=torch.bfloat16)

input_text = "Generate relevant, interesting, factual short headline from this news article in telugu language\n <Your Telugu news article text here>"
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")

outputs = model.generate(**input_ids)
print(tokenizer.decode(outputs[0]))

Quantized Versions through bitsandbytes

• Using 8-bit precision (int8)

# pip install bitsandbytes accelerate
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig

quantization_config = BitsAndBytesConfig(load_in_8bit=True)

tokenizer = AutoTokenizer.from_pretrained("saidines12/telugu-news-headline-generation")
model = AutoModelForCausalLM.from_pretrained("saidines12/telugu-news-headline-generation", quantization_config=quantization_config)

input_text = "Generate relevant, interesting, factual short headline from this news article in telugu language\n <Your Telugu news article text here>"
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")

outputs = model.generate(**input_ids)
print(tokenizer.decode(outputs[0]))

• Using 4-bit precision

# pip install bitsandbytes accelerate
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig

quantization_config = BitsAndBytesConfig(load_in_4bit=True)

tokenizer = AutoTokenizer.from_pretrained("saidines12/telugu-news-headline-generation")
model = AutoModelForCausalLM.from_pretrained("saidines12/telugu-news-headline-generation", quantization_config=quantization_config)

input_text = "Generate relevant, interesting, factual short headline from this news article in telugu language\n <Your Telugu news article text here>"
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")

outputs = model.generate(**input_ids)
print(tokenizer.decode(outputs[0]))

Other optimizations

• Flash Attention 2

First make sure to install flash-attn in your environment pip install flash-attn

model = AutoModelForCausalLM.from_pretrained(
    model_id, 
    torch_dtype=torch.float16, 
+   attn_implementation="flash_attention_2"
).to(0)

Inputs and outputs

• Input: Text string, such as a question, a prompt, or a document to be summarized.
• Output: Generated English-language text in response to the input, such as an answer to a question, or a summary of a document.

Uses

Direct Use

This model is designed for generating Telugu news headlines from article content. It can be used by:

• News organizations for automated headline generation
• Content creators working with Telugu news content
• Researchers studying Telugu natural language generation

Out-of-Scope Use

• The model should not be used for generating fake news or misleading headlines
• Not suitable for non-Telugu content
• Not designed for general text generation tasks
• Should not be used for classification or other non-headline generation tasks

Bias, Risks, and Limitations

• May reflect biases present in Telugu news media
• Performance may vary based on news domain and writing style
• Limited to the vocabulary and patterns present in the training data
• May occasionally generate grammatically incorrect Telugu text
• Could potentially generate sensationalized headlines

Recommendations

• Use with human oversight for published content
• Verify generated headlines for accuracy
• Monitor output for potential biases
• Implement content filtering for inappropriate generations
