Api Calls
Api Calls are function invocations made to application programming interfaces (APIs), enabling software applications to request specific services or data from external systems. In the context of large language models and AI assistants, API calls facilitate interaction between client applications and cloud-based AI services, allowing developers to leverage pre-built models and tools without building the underlying infrastructure themselves. These calls typically involve sending formatted requests to remote servers that process the input and return a structured response.
The integration of such calls is central to Retrieval-Augmented Generation (RAG) architectures, where AI systems retrieve relevant information from external databases to enhance response accuracy. To streamline this process, Google has released a File Search tool within the Gemini API. This feature simplifies the implementation of RAG workflows by providing a standardized method for applications to query and retrieve data from files, reducing the complexity of managing external data sources manually.
