Foundation models are large-scale AI systems trained on vast, primarily unstructured datasets. By leveraging self-supervised learning on diverse corpora, these models gain powerful capabilities—ranging from text generation and question answering to code completion, image captioning, and more. While foundation models unlock many possibilities in generative AI, they also introduce risks such as biased or incorrect outputs. Deploying them safely requires clear guidelines, robust safeguards, and ongoing research to ensure reliability and ethical use.
Foundation models may produce biased, inaccurate, or unsafe outputs if not properly monitored. Always implement human-in-the-loop review and adhere to ethical AI frameworks.

​
Training Data and Capabilities

Foundation models are typically pre-trained on massive datasets tailored to each modality:
  • Text: Web text, Wikipedia, books
  • Images: Public domain image collections, extensive visual datasets
  • Audio/Video: Speech corpora, video repositories
This extensive pre-training provides a rich foundation for downstream tasks through fine-tuning or prompt engineering.

​
Multimodal Support

Many foundation models handle multiple modalities—text, images, video, and audio—enabling seamless cross-modal applications.
The image is a diagram showing different types of foundation models, categorized into text, image, video, and audio. Each category is represented with an icon and connected to a central "Foundation Models" icon.
Multimodal models can be extended to new domains by fine-tuning on task-specific datasets, such as adding domain-specific images or specialized speech recordings.

​
Common Use Cases

After pre-training, foundation models can be adapted to a wide array of scenarios:
