# Models

Palantir provides a common interface to integrate models from a range of different sources. Models can be integrated from:

1. [Models trained in Palantir](../model-asset-code-repositories/index.md).
2. [Model files trained outside of Palantir and uploaded as an unstructured dataset](../model-asset-files/index.md).
3. [Models containerized outside of Palantir and pushed into the Foundry Docker registry](../container-overview/index.md).
4. [Models trained and hosted outside of Palantir](../external-model-connection/index.md).

All models can be productionized and connected to operational applications through the [Modeling Objectives](../../model-integration/objectives/index.md) application.

## Model adapters

Models in Palantir comprise of two components:

* **Model artifacts:** The model files, parameters, weights, container, or credentials where a trained model is saved.
* **[Model adapter](../model-adapter-overview/index.md):** The logic and the environment dependencies that describe how Foundry should interact with the **model artifacts** to load, initialize, and perform inference with the model.
