Foundation model
A foundation model is like a 'jack-of-all-trades' AI that has been trained on a massive amount of information so it can handle many different jobs, like writing, coding, or summarizing. The 'frontier' models are simply the newest, smartest versions of these tools that lead the pack in performance.
A foundation model is a large-scale neural network pre-trained on diverse, unlabeled datasets that can be adapted to a wide range of downstream tasks through fine-tuning or in-context learning. 'Frontier models' refer to the current state-of-the-art class of these systems that exhibit the highest levels of capability and scale.
A model pre-trained on broad data at scale that serves as a base for many downstream tasks via prompting or fine-tuning; 'frontier model' denotes the most capable current generation.
