Helium can be found on the Huggingface Hub
In the following, we demonstrate how to use helium-1-preview for the inference.
>>> from transformers import AutoModelForCausalLM, AutoTokenizer
>>> model = AutoModelForCausalLM.from_pretrained("kyutai/helium-1-preview-2b", device_map="auto")
>>> tokenizer = AutoTokenizer.from_pretrained("kyutai/helium-1-preview-2b")
>>> prompt = "Give me a short introduction to large language model."
>>> model_inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
>>> generated_ids = model.generate(model_inputs.input_ids, max_new_tokens=512, do_sample=True)
>>> generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)]
>>> response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
