# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("anixlynch/textgen-gpt2-benchmark")
model = AutoModelForCausalLM.from_pretrained("anixlynch/textgen-gpt2-benchmark")
# Create generation pipeline
generator = pipeline(
"text-generation",
model=model,
tokenizer=tokenizer,
pad_token_id=tokenizer.eos_token_id
)
# Example generation
prompt = "Machine learning is revolutionizing"
output = generator(
prompt,
