We explore supervised multitask pre-training by proposing ***Instruction Pre-Training***, a framework that scalably augments massive raw corpora with instruction-response pairs to pre-train language models. The instruction-response pairs are generated by an efficient instruction synthesizer built on open-source models. In our experiments, we synthesize 200M instruction-response pairs covering 40+ task categories to verify the effectiveness of *Instruction Pre-Training*. ***Instruction Pre-Training* outperforms *Vanilla Pre-training* in both general pre-training from scratch and domain-adaptive continual pre-training.** In pre-training from scratch, *Instruction Pre-Training* not only improves pre-trained base models but also benefits more from further instruction tuning. In continual pre-training, *Instruction Pre-Training* enables Llama3-8B to be comparable to or even outperform Llama3-70B.

**************************** **Updates** **************************** * 2024/7/31: Updated pre-training suggestions in the `Advanced Usage` section of [instruction-synthesizer](https://huggingface.co/instruction-pretrain/instruction-synthesizer) * 2024/7/15: We scaled up the pre-trained tokens from 100B to 250B, with the number of synthesized instruction-response pairs reaching 500M! Below, we show the performance trend on downstream tasks throughout the pre-training process:

### 1. Basic Usage: Synthesize instruction-response pairs based on a given raw text **💗 Here is an amazing demo that implements our approach: [davanstrien/instruction-synthesizer](https://huggingface.co/spaces/davanstrien/instruction-synthesizer) 💗**

In addition, there are a number of free events and fishing clinics taking place across the state to encourage New Yorkers to enjoy the great outdoors.

### 2. Advanced Usage: Convert Raw Corpora into Instruction-Augmented Corpora at Scale We use vLLM to accelerate the synthesis process. On a single A100-80GB GPU, it takes about 2 days to synthesize instruction-response pairs for 1 billion tokens of raw corpora.
Click to expand 1). Set up dependencies: ```bash git clone https://github.com/microsoft/LMOps.git cd LMOps/instruction_pretrain ``` Install vLLM with pip or from [source](https://vllm.readthedocs.io/en/latest/getting_started/installation.html#build-from-source): ```bash pip install vllm ``` 2). Synthesize and Templify Few-shot Examples for Pre-Training A one-shot example consists of a piece of raw text followed by its instruction-response pairs. We conduct multi-round inferece to synthesize few-shot examples: the instruction-response pairs of different raw texts share the same pattern. Suppose there are N pieces of raw text in the corpora, and you would like to covert them into M-shot examples: ```python from vllm import LLM, SamplingParams from utils.read_compre import get_dataset, cook_pt_entries, run # Put your list of raw texts here raw_texts = [ "Genetically and medically susceptible workers.\nThe likelihood of an individual becoming ill from a hazardous material or condition is strongly influenced by both their genetic makeup and their underlying state of health. Although the past decade has seen great advances in understanding human variation in health and genetic polymorphisms and in the diagnosis and treatment of disease, much less progress has been made in effectively using this information to protect worker health. Scientific evidence for increased susceptibility often is weak and rarely satisfies legal thresholds for sufficient risk to warrant exclusion from a particular job. When public safety is a major concern, many legally mandated exclusions are not well justified. Medical opinions about fitness to work should be based upon a systematic and credible analysis of the condition, its relationship to ability and risk for a particular job, and knowledge of possible accommodations. Conclusions should reflect the limitations of scientific knowledge and guidance from antidiscrimination legislation.", "Exclusive Breastfeeding for Twin Babies and Its Influencing Factors: A Study in East Java, Indonesia.\nThis study aimed to identify the factors that influence the success of exclusive breastfeeding in twins. This cross-sectional study was conducted on 184 mothers who had twins aged 6-23 months in Malang Raya, East Java, Indonesia and used the consecutive sampling technique. The data was collected through distributing questionnaires containing questions related to knowledge about exclusive breastfeeding, breastfeeding self-efficacy, and the support of family and certified health workers. Multinomial regression statistical test results show that the most influential factor for the success of exclusive breastfeeding with twins was breastfeeding self-efficacy (OR 0.111; 95% CI 0.033-0.387). A high level of breastfeeding self-efficacy can increase a mother's confidence to be able to provide exclusive breastfeeding for twins. This study suggests that nurses can provide breastfeeding counselling to improve breastfeeding self-efficacy."] N = len(raw_texts) # Number of raw texts M = 2 # M-shot example max_model_len = 4096 # max squence len of the LM you intend to pre-train max_new_tokens = 400 # max number of tokens for the augmented instruction-response pairs # Create a sampling params object. sampling_params = SamplingParams(temperature=0, max_tokens=max_new_tokens) # Load the model and tokenizer llm = LLM(model="instruction-pretrain/instruction-synthesizer", max_model_len=max_model_len) # 1. multi-round inference to get the prediction prev_examples = [] BSZ = (N+M-1)//M for round in range(M): cur_raw_texts = raw_texts[round*BSZ: (round+1)*BSZ] # load data split = get_dataset(prev_examples=prev_examples, cur_raw_texts=cur_raw_texts, max_model_len=max_model_len, max_new_tokens=max_new_tokens) prev_examples = run(split, llm, sampling_params) # 2. templify the data for subsequent pre-training instruction_augmented_texts = [] for idx, entry in enumerate(prev_examples): texts = cook_pt_entries(read_collection=entry, random_seed=idx+12345) # change random seed for each entry for diveristy instruction_augmented_texts.extend(texts) # 3. print out the instruction_augmented_texts for idx, text in enumerate(instruction_augmented_texts): print(text) # Now you can use `instruction_augmented_texts` for pre-training! ```
**Pre-Training Suggestions:** Except for the pre-training data, *Instruction Pre-Training* keeps all other settings the same as *Vanilla Pre-Training*. Therefore, you can easily use any training framework, such as [OLMo](https://github.com/allenai/OLMo) (for pre-training from scratch) and [LLaMA-Factory](https://github.com/hiyouga/LLaMA-Factory) (for continual pre-training), to train on the templified instruction-augmented corpora. 1. For general pre-training from scratch, we recommend setting M = 2 and mixing the instruction-augmented corpora with unchanged raw corpora. 2. For domain-adaptive continual pre-training, we recommend setting M = 3 and mixing the instruction-augmented corpora with general instructions from [OpenOrca](https://huggingface.co/datasets/Open-Orca/OpenOrca) at a 1:1 ratio (counted by tokens). Each example from OpenOrca is formulated as "{question} {response}", with a white-space used to connect the question and response. Let's try our method in continual pre-training for a quick start---it works easily!
