## Definition
|
||||
Foundation Models(基础模型)是拥有数十亿参数的大规模预训练模型,是生成式 AI 的核心驱动力。Amazon 认为大多数客户体验和应用将被生成式 AI 重塑,而生成式 AI 的力量来自于基础模型。
|
||||
|
||||
## Key Properties
|
||||
- **规模**: 数十亿参数(billions of parameters)
|
||||
- **预训练**: 在大规模通用数据上预训练
|
||||
- **可定制**: 支持微调(Fine-tuning)、持续预训练、RAG 等数据定制技术
|
||||
- **多模态**: 可处理文本、图像、代码等多种模态
|
||||
