API integration incorporates functionality or data from a software service into an application through its application programming interface. In AI products, it connects pretrained models and existing components to user-facing systems, workflows, and interactions. section 12.1.2
AI engineering commonly uses API integration to:
- Implement AI models in production systems. section 12.1.2
- Build AI-powered applications and workflows. section 12.1.2
- Optimize model inference and user interactions. section 12.1.2
AI-powered product integration
A team can begin with pretrained models and existing components, using tools such as the OpenAI API, LangChain, Hugging Face, or vector databases before considering custom model training or fine-grained optimization. section 12.1.2
