Promptim experiments with automated prompt optimization for LLM apps

LangChain has introduced Promptim, an experimental library for automated prompt optimization. The project is meant to help teams improve model performance, reduce manual prompt work, and adapt prompts across model changes.

Prompt optimization remains a practical bottleneck for LLM applications. Teams often rely on manual iteration, which can be slow, inconsistent, and hard to reproduce.

Promptim reflects a broader push to turn prompt engineering into a more systematic workflow with evaluations, search, and measurable performance changes.
