Which of the following are the impacts of the development of large models?

The emergence of large AI models (e.g., GPT, Pangu, BERT) has led to:

C:Improved accuracy and efficiency in NLP and other AI tasks because of their ability to capture deep semantic and contextual information.

D:Increased data privacy and security concerns, as large models require massive datasets which may contain sensitive or proprietary information.Ais false — large models increase pre-training costs.Bis false — small and domain-specific models still play important roles due to efficiency and deployment constraints.

Exact Extract from HCIP-AI EI Developer V2.5:

"Large models improve task performance but raise privacy and security concerns. They do not necessarily reduce training cost or eliminate the need for smaller models."
