Foundational model

As explained in Financial AI in Practice

A foundation model is a large, broadly trained model that can be adapted or guided for many downstream tasks.

How Financial AI in Practice covers it

How deep it goes

Defines the shift from task-specific training to AI engineering without detailing implementation steps.

Examples

Contrasts market-sentiment classification and research-report summarization as formerly separate modeling tasks.

What you can do after

Apply it by steering a general-purpose model safely and effectively toward a specific business problem.

How it connects

Connects foundation models with large language models, natural language processing, and AI engineering.
