• call generative models through an API
• deploy models to generate predictions
• evaluate and monitor models
• build and manage agents

We file it under Data science and machine learning, the category of tools to train and deploy models, and it also overlaps with model APIs and platforms and aI agent builders. The category lists 6 verified tools on this site.

The publisher is Google LLC, based in United States. The service launched in 2021, which gives it some track record.

Who is it for?

It is mostly useful to these profiles: developers, data analysts, and researchers. The need it covers is simple to state: train and deploy models.

Gemini platform (Vertex AI) is a good candidate if:
