The Lodash for GenAI: Real Value + Consistent + Model-Agnostic

ActiveGenie is a developer-first library for GenAI workflows, designed to help you compare, rank, and score LLM outputs with consistency and model-agnostic flexibility. Think of it as the Lodash for GenAI: built for real value, consistent results, and freedom from vendor lock-in. It solves the biggest pain in GenAI today: getting predictable, trustworthy answers across use cases, models, and providers.

Behind the scenes, a custom benchmarking system keeps everything consistent across LLM vendors and versions, release after release.
