   Scaling LLM Experimentation

   Data Preprocessing

   Data preprocessing is a vital step in LLM experimentation SageMaker Pipelines can automate this by setting up a series of steps to clean transform and prepare data for training For instance you can develop a pipeline that fetches raw text data from S3 tokenizes the text and saves the processed data back to S3

   Model Training

   Training LLMs demands substantial computational power SageMaker Pipelines can manage distributed training jobs using SageMaker039s managed training infrastructure You can set up a training step in your pipeline that includes the training script instance type and hyperparameters

   Experiment Tracking with MLflow

   MLflow can be combined with SageMaker to monitor experiments By logging parameters metrics and artifacts you can track different runs and compare their outcomes

   Model Evaluation and Deployment

   Post-training the model needs to be evaluated and deployed SageMaker Pipelines can include evaluation steps to gauge model performance and deployment steps to launch the model to a SageMaker endpoint
