    Create a fine-tuning recipe for Llama3 70B model.

    This function sets up a complete configuration for fine-tuning, including
    model, trainer, data, logging, optimization, and resumption settings.
    The recipe uses LoRA (Low-Rank Adaptation) for efficient fine-tuning, unless peft_scheme is set to None.

    Args:
        dir (Optional[str]): Directory for saving logs and checkpoints.
        name (str): Name of the fine-tuning run.
        num_nodes (int): Number of compute nodes to use.
        num_gpus_per_node (int): Number of GPUs per node.
        peft_scheme (Optional[str]): Name of the peft scheme to use for fine-tuning.
            Allowed values: 'lora'/'dora'/'none'/None.
        seq_length (int): Maximum number of tokens per microbatch.
        packed_sequence (Optional[bool]): If true, fine-tuning sequences will be packed into batches up to the given
            maximum seq_length for better efficiency. By default, this value equals performance_mode.
        performance_mode (bool): If true, enables optimizations for maximum performance.

    Returns:
        run.Partial: Partial configuration for fine-tuning.

    Examples:
        CLI usage:
            $ nemo llm finetune --factory llama3_70b
            $ nemo llm finetune --factory "llama3_70b(num_nodes=4, name='my_70b_finetune')"

        Python API usage:
            >>> recipe = finetune_recipe(name="llama3_70b_finetune", num_nodes=4)

        This recipe uses the SQuAD dataset for fine-tuning. Be aware that fine-tuning a 70B model
        requires substantial computational resources.
