Custom training in Google Cloud's Gemini Enterprise Agent Platform (formerly known as Vertex AI) provides a mechanism for developing machine learning (ML) models with your own defined algorithms while allowing for complex configurations. Using the Gemini Enterprise Agent Platform's managed training service, you can operationalize large-scale modeling.
This saves time, effort, and tedious work, allowing developers to focus on other tasks.

The Significance of Custom Training in the Gemini Enterprise Agent Platform
Custom training in the Gemini Enterprise Agent Platform allows you to train machine learning models using your own algorithms and data, meaning you can use Gemini Enterprise to run training applications based on any ML framework on Google Cloud infrastructure. This gives you full control and flexibility over the model architecture, framework, and training code.
There are many challenges to operationalizing model training, from the time and cost needed to train models to the skills required to manage the compute infrastructure.
Gemini Enterprise helps alleviate these challenges while providing a host of benefits, including:
- Fully Managed Compute Infrastructure: Model training on the Gemini Enterprise Agent Platform is a fully managed service. This means there's no need for the administration of physical infrastructure. You can train ML models without needing to manage servers, and you only pay for the compute resources that you consume. Gemini Enterprise also tackles tasks like job logging, queuing, and monitoring.
- Distributed Training: Gemini Enterprise's Reduction Server is an all-reduce algorithm that can increase throughput and reduce the latency of multi-node distributed training on NVIDIA graphics processing units. This saves time and helps reduce the cost of large training jobs.
- Quality Performance: All Gemini Enterprise training jobs are optimized for ML model training. This provides faster performance than directly running your training application on a GKE cluster. Using the Gemini Enterprise TensorBoard Profiler, you can also identify and debug issues.
- Hyperparameter Optimization: Hyperparameter tuning jobs can run multiple trials of your training application using different values. All you have to do is specify a range of values to test, and the Gemini Enterprise Agent Platform discovers the optimal values for your model in that range.
- Security: Gemini Enterprise provides a host of enterprise security features, including: VPC peering, VCP Service Controls, customer-managed encryption keys, identity and access management, and data isolation with single-tenant project boundaries.
- MLOps Integrations: The Gemini Enterprise Agent Platform provides a host of MLOps tools you can use to run experiments, track ML metadata, manage your models, perform feature engineering, and more.
Workflow for Custom Training in Gemini Enterprise
The custom training workflow on the Gemini Enterprise Agent Platform follows this process:
Pull from Cloud Storage, BigQuery, or NFS shares on Google Cloud. You can also use a Gemini Enterprise-managed dataset to benchmark custom vs. AutoML model performance.
Choose a prebuilt or custom Docker container image and package your training application into the appropriate format. Follow Google's training code best practices throughout.
Select compute resources, choose single-node or distributed training, and set your container configurations. The platform provisions and decommissions VMs automatically.
Launch a custom job, hyperparameter tuning job, or training pipeline via the Cloud console, CLI, Python SDK, or the Gemini Enterprise API.
Let's take a look at these steps in more detail.
Load Training Data
First, you need to load your data. To follow best practices, it's recommended to use one of these Google Cloud services as your data source:
- Cloud Storage
- BigQuery
- NFS shares on Google Cloud
In addition, you can specify a Gemini Enterprise-managed dataset as a data source to train your model. By training a custom model and an AutoML model with the same dataset, you can compare performance of the two.
Prepare Training Application
To prepare your data, you need to determine a type of container image to use and package your training application into a supported format based on the chosen container image.
Gemini Enterprise runs training applications in a Docker container image, which is a self-contained software package that includes code and dependencies and can run in almost any computing environment. You can either provide the URI of a prebuilt container image or create and upload a custom image.
It's also important to follow the training code best practices for the Gemini Enterprise Agent Platform.
Configure Training Job
A Gemini Enterprise training job performs a range of tasks:
- Provisions one or more virtual machines (VM).
- Runs your containerized training application on the provisioned VMs.
- Deletes VMs once job training is finished.
Learn more about the three types of training jobs Gemini Enterprise offers for running your training application. Then, you'll need to choose the compute resources to use for a training job; Gemini Enterprise supports single-node training and distributed training.
Finally, you'll need to select the container configurations you need. These container configurations will change depending on if you're using a pre-built or custom image.
Create a Training Job
Once your data and application are prepared, you can run your training application by creating one of the following jobs:
- Create a custom job.
- Create a hyperparameter tuning job.
- Create a training pipeline.
You can use the Google Cloud console, Google Cloud CLI, Gemini Enterprise SDK for Python, or the Gemini Enterprise API to create your training job.
