Why experienced developers delete frameworks, avoid fine-tuning, and ship faster using surprisingly simple principles
Building with LLMs feels like navigating a minefield of overhyped frameworks and premature optimization.
This article delves into the practical approaches employed by experienced engineers while working with large language models (LLMs). It emphasizes the importance of prototyping with frameworks for initial development and then transitioning to custom solutions for production. The piece discusses the often unnecessary nature of fine-tuning, supporting the preference for prompt engineering over resource-heavy model adjustment. It also underscores the need for monitoring business outcomes rather than just technical metrics, advocating for the use of robust orchestration tools. Overall, the article is a guide to shipping reliable systems efficiently by focusing on simplicity and practicality in engineering methodology.
