Common questions

What is the difference between evidently and simple-evals?

When should I choose evidently over simple-evals?

However, advanced or specific-use-case features might necessitate community or own; Requirements: Installation straightforward through PyPI or Conda Forge.; Tags unique to evidently: data-validation, data-science, data-drift, html-report; Also covers Data & Retrieval; Use Evidently when you need a robust solution to evaluate model performance across various stages of the machine learning lifecycle, including generative AI applications.

When should I choose simple-evals over evidently?

Do not opt for Evidently if your organization strictly prefers lightweight, minimalistic tools; it can be more feature-rich than necessary for simple monitoring tasks.

When should I avoid simple-evals?

LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.

Is evidently or simple-evals more popular on GitHub?
