Foundation Model
A large, general-purpose AI model trained on broad data and then adapted, through prompting, tuning, or fine-tuning, to specific tasks such as RPG code generation.
Foundation models are the base models underlying products like watsonx.ai and the fine-tuned model IBM Bob uses for RPG. IBM's own Granite family is one example; other vendors offer their own foundation models. A foundation model can be adapted to a narrow domain, such as RPG source code, through additional training or prompt engineering, rather than being built from scratch for that one task.
