Foundation Model
also base model
A foundation model is a large model trained on broad data that can be adapted to many tasks, such as Claude, GPT, or Gemini.
Analogy
Like a versatile all-purpose flour you can use as the base for many different recipes.
Why it matters
Choosing the right foundation model and tier sets the baseline quality, speed, and cost for every AI step in your automations.
In practice
Claude is a foundation model you can prompt for writing, classification, or extraction without retraining it.
