Usage

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer

model = AutoModelForSeq2SeqLM.from_pretrained("KamilHugsFaces/t5-gemma-reasoning-v4")
tokenizer = AutoTokenizer.from_pretrained("KamilHugsFaces/t5-gemma-reasoning-v4")

# Format input
input_text = "entailment: [Your claim and evidence here]"
inputs = tokenizer(input_text, return_tensors="pt", max_length=250, truncation=True)

# Generate prediction
outputs = model.generate(**inputs, max_new_tokens=8)
prediction = tokenizer.decode(outputs[0], skip_special_tokens=True)
# Output: "true" or "false"
