This GPT-2 model was fine-tuned using +672k tweets from twitter/X. The classification accuracy is 98%.

The number of labels is 3: {0: Negative, 1: Neutral, 2: Positive}

This is an example to use it

bash

from transformers import AutoTokenizer
from transformers import pipeline
from transformers import AutoModelForSequenceClassification
import torch

checkpoint = 'kumo24/gpt2-sentiment'
tokenizer=AutoTokenizer.from_pretrained(checkpoint)
id2label = {0: "negative", 1: "neutral", 2: "positive"}
label2id = {"negative": 0, "neutral": 1, "positive": 2}
    

if tokenizer.pad_token is None:
    tokenizer.add_special_tokens({'pad_token': '[PAD]'})

model = AutoModelForSequenceClassification.from_pretrained(checkpoint, 
                                                       num_labels=3,
                                                       id2label=id2label, 
                                                       label2id=label2id)

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.to(device)


sentiment_task = pipeline("sentiment-analysis", 
                          model=model, 
                          tokenizer=tokenizer)

print(sentiment_task("Michigan Wolverines are Champions, Go Blue!"))
