Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer

# Load the model and tokenizer
# The 'trust_remote_code=True' flag is essential for custom models
model = AutoModelForCausalLM.from_pretrained(
    "persadian/persadian-nano-v4",
    trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained("persadian/persadian-nano-v4")

# Move model to GPU if available
import torch
device = "cuda" if torch.cuda.is_available() else "cpu"
model = model.to(device)

# Generate text
prompt = "Once upon a time"
inputs = tokenizer(prompt, return_tensors="pt").to(device)
outputs = model.generate(**inputs, max_new_tokens=50, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
