Usage

from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer
import torch

model_name = "sudy-super/Contrail-200m-64k"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto", torch_dtype=torch.bfloat16)
streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)

if torch.cuda.is_available():
    model = model.to("cuda")

prompt = "AIによって私達の暮らしは、"

with torch.no_grad():
  token_ids = tokenizer.encode(prompt, return_tensors="pt")
  output_ids = model.generate(
      input_ids=token_ids.to(model.device),
      min_new_tokens=10,
      max_new_tokens=100,
      do_sample=True,
      temperature=0.7,
      streamer=streamer,
  )
