💬 How to Use

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

tokenizer = AutoTokenizer.from_pretrained("iamhariraj/DialoGPT-small-Rick")
model = AutoModelForCausalLM.from_pretrained("iamhariraj/DialoGPT-small-Rick")

chat_history_ids = None

print("Talk to Rick (type 'quit' to exit)")
while True:
    user_input = input("You: ")
    if user_input.lower() == "quit":
        break

    input_ids = tokenizer.encode(
        user_input + tokenizer.eos_token,
        return_tensors="pt"
    )

    if chat_history_ids is not None:
        input_ids = torch.cat([chat_history_ids, input_ids], dim=-1)

    chat_history_ids = model.generate(
        input_ids,
        max_length=1000,
        pad_token_id=tokenizer.eos_token_id,
        no_repeat_ngram_size=3,
        do_sample=True,
        top_k=100,
        top_p=0.7,
        temperature=0.8
    )

    response = tokenizer.decode(
        chat_history_ids[:, input_ids.shape[-1]:][0],
        skip_special_tokens=True
    )
    print(f"Rick: {response}")
