AI platform
An AI platform is a shared foundation that brings together, in one place, the tools and infrastructure needed to build and serve AI, from data preparation to model training, deployment and operations. It is also called an ML platform.

What's inside
It usually includes a data layer for collecting and organizing data, a development environment for experimenting with and training models, experiment tracking for recording experiments, a model registry for storing finished models, model serving for deploying models as services, and monitoring for watching performance in production. Underneath sits infrastructure such as GPU clusters and Kubernetes. As generative AI spreads, platforms increasingly also include an LLM gateway that puts multiple LLMs behind a single access point, prompt management, and agent and tool connection features. Security and access control, along with cost management, apply across every layer.

Why it matters
When each team sets up its own servers and tools, work gets duplicated and it becomes hard to trace where and how a model was built. An AI platform standardizes this process and shortens the time from experiment to service. It saves money by letting multiple teams share expensive GPUs, and it makes governance (control and oversight) easier by managing data access permissions and model approval procedures in one place.
Things to know
The first question is whether to build or buy. Managed services from cloud companies (e.g. Amazon SageMaker, Google Vertex AI, Azure Machine Learning) let you start quickly but can easily lock you into one vendor, while assembling open-source tools yourself gives freedom but carries a heavy operational burden. Also, if a platform is built far larger and more complex than actual needs, it can become an 'empty platform' that teams don't use, so it is better to start with the most frequently used features.
Example
As with the news covered on this site, 'AWS adds support for creating and managing HyperPod Spaces directly in SageMaker Studio', cloud AI platforms keep adding features for creating and managing large-scale GPU training environments directly from the development interface. Inside companies, too, it is common to unify the workflow so that data and AI teams pull data, train models on a single platform, and deploy only approved models to services through the registry.
