API

An API (Application Programming Interface) is a set of protocols and tools that allow different software to communicate with each other. In the context of artificial intelligence, language model APIs, such as those from OpenAI, Anthropic, Google, or Mistral, allow developers to integrate AI model capabilities directly into their own applications, without having to manage the model's infrastructure.

Definition

Through APIs, a company can integrate ChatGPT into its own customer support platform, build a custom AI assistant for its employees, automate document generation, or create workflows that combine AI with other business systems. APIs are billed by usage (per token consumed), which makes them scalable but requires attention to cost optimization.

For business teams that want to go beyond consumer use of AI models, understanding APIs is essential. Grace prepares professionals to use AI effectively at every level, from the individual user on a consumer interface to teams integrating AI into workflows via API.
