How is a model platform different from a single AI app?

An app wraps one model into a finished product with a fixed interface. A model platform gives you raw access to the models themselves through an API, so you can build your own product or route between several models.

Do I need to train a model to use these?

No. The point is access to already-trained foundation models: you send inputs and get outputs. Some platforms also let you fine-tune a base model on your own data, but that is optional.

Do they offer open-source or proprietary models?

It varies. Some aggregate both behind one API, others specialize in open models you can self-host or proprietary models like GPT and Claude. Open models trade some quality for control and lower cost; proprietary ones often lead on capability.

What are AI model platforms?

This category covers platforms that provide access to AI foundation models: the large language, image, video and audio models that power generative apps. They expose these models through APIs, playgrounds or hosting, so developers can call them without training their own.

Core features

API access to hosted foundation models
One interface across model providers
Image, video, audio and text models
Playgrounds for testing prompts
Usage-based, pay-as-you-go pricing
Open and proprietary model options

Who uses AI model platforms

Developers

Call ready-made models through an API instead of training and hosting your own.

AI product teams

Compare and switch between model providers behind one interface.

Researchers & tinkerers

Test the latest open and proprietary models in a playground.

How AI model platforms work

These platforms host or aggregate trained models and serve them over an API. A request sends your prompt or input to the chosen model, which runs on the provider's infrastructure and returns the generated text, image, audio or video, billed by usage.
