Choosing between using an existing generative AI model via an API or training a custom model involves trade-offs in speed, cost, and control. For many businesses, leveraging an API is a faster and more affordable initial approach, suitable for tasks like support assistants or document summarization. Customization becomes necessary when specialized terminology, unique tone, or data sensitivity requires a tailored solution, often involving fine-tuning open models or implementing retrieval-augmented generation (RAG). A common strategy is to start with an API to validate a use case, then consider customization if performance gaps or data control needs justify the increased investment. AI
