  • llm_int8_enable_fp32_cpu_offload: False
  • llm_int8_has_fp16_weight: False
  • bnb_4bit_quant_type: nf4
  • bnb_4bit_use_double_quant: True

Model Inference

input_text = "participant safety -->: "
batch = tokenizer(input_text, return_tensors='pt')

with torch.cuda.amp.autocast():
    output_tokens = model.generate(**batch, max_new_tokens=50)

print('\n\n', tokenizer.decode(output_tokens[0], skip_special_tokens=True))
