A small team considers using a suitable pretrained foundation model instead of training a comparable broad model from scratch. Which statements describe realistic advantages and remaining responsibilities? Select 2 answers.

1. Every pretrained model can answer any company question correctly without access to company information.
2. The team must still evaluate use-case quality, cost, data handling, and deployment constraints.
3. Pre-training can provide reusable capabilities and reduce the time and resources needed to reach an initial application prototype.
4. A pretrained model removes all need for access controls on sensitive prompts.
5. Using a pretrained model eliminates all ongoing inference expenses.
