I built an LLM eval framework from scratch: Lessons learned
Sharing my journey of building an LLM evaluation framework and key lessons learned.
One weekend, I created an LLM evaluation framework in about two hundred lines of Python. While it initially worked well, six months later, it became chaotic. The framework itself didn't fail; rather, it was the overlooked complexities that caused issues. This experience highlights the importance of understanding which components to build and which to buy, offering valuable insights for engineers.
