Hey Product Hunt! 👋 I’m Leo, the creator of Leo Prompt Optimizer. I built this because I was tired of the 'trial-and-error' loop of prompt engineering. One day a prompt works; the next day, after a minor tweak or a model update, it breaks. I wanted a way to treat prompts like code: with structured frameworks, automated optimization, and objective benchmarks. Leo is a lightweight Python SDK and...
Leo: The Prompt Engineering SDKOptimize, benchmark & evaluate LLM prompts with 1 command.
Bring rigor to your AI agents.
Trusted by 8,500+ developers, Leo is a lightweight Python SDK designed to integrate prompt optimization directly into your CI/CD pipelines or internal tools.
Stop shipping prompts that only work "most of the time." Leo provides a structured way to optimize drafts into role-based instructions and automatically evaluates them against real-world test cases using G-Eval and Hallucination Accuracy metrics. It's the missing piece of the LLM DevStack.
