Example Code

This is example code on how to run the chat model.

    from transformers import AutoTokenizer
    from open_lm.utils.transformers.hf_config import OpenLMConfig
    import torch
    from open_lm.utils.transformers.hf_model import OpenLMConfig, OpenLMforCausalLM

    # Load the model and tokenizer
    model_name = "mlfoundations/dclm-it"
    # Load the configuration, tokenizer, and model separately
    config = OpenLMConfig.from_pretrained(model_name)
    tokenizer = AutoTokenizer.from_pretrained(model_name)
    model = OpenLMforCausalLM.from_pretrained(model_name, torch_dtype=torch.bfloat16, device_map="cuda", config=config)

    # Define the prompt format
    def create_prompt(instruction):
        PROMPT = '''Below is an instruction that describes a task.\n\nWrite a response that appropriately completes the request.\n\n### Instruction:\n{instruction}\n\n### Response:'''
        return PROMPT.format(instruction=instruction)
    # Example instruction
    instruction = "Give me a poem about Sachin Tendulkar."
    # Create the prompt
    prompt = create_prompt(instruction)
    # Tokenize the input
    input_ids = tokenizer.encode(prompt, return_tensors="pt").to(torch.device('cuda'))
    # Generate the response
    output = model.generate(input_ids, max_length=500, top_p=.95, do_sample=True, temperature=0.3)
    # Decode the response
    response = tokenizer.decode(output[0][len(input_ids[0]):])
    response = response.split("<|endoftext|>")[0]
    # Print the response
    print(response)

Limitations and Biases

While DCLM-Baseline-7B demonstrates strong performance across a range of tasks, it's important to note:

1. The model may exhibit biases present in its training data, which is derived from web crawl data.
2. It has not undergone specific alignment or safety fine-tuning, so outputs should be used with caution.
3. Performance on tasks not included in the evaluation suite may vary.
4. The model's knowledge is limited to its training data cutoff date.

Ethical Considerations

Users should be aware that this model, like all large language models, can potentially generate harmful or biased content. It should not be used for making decisions about individuals or in sensitive applications without appropriate safeguards and human oversight.
