It's open-source,轻 ## Choose when ### Choose guidance if… - guidance is primarily Jupyter Notebook; moby is Go. - License: guidance is MIT, moby is Apache-2.0. - Tags unique to guidance: backend support, control language, language-models, pip-installable. - When you need a specific language to finely control various LLM backends including Transformers, llama.cpp, and OpenAI ### Choose moby if… - moby is primarily Go; guidance is Jupyter Notebook. - License: moby is Apache-2.0, guidance is MIT. - Tags unique to moby: containers, docker, go, golang. - Also covers Developer Tools. - moby ships Docker support for self-hosted deployment. ## When NOT to use guidance - When your project is strictly confined to using only one type of backend which you can manage without a specialized control language - If your development environment does not support or prefer Jupyter Notebooks, Guidance may not be the best choice ## When NOT to use moby - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between guidance and moby? guidance: A guidance language for controlling large language models.. moby: The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems.
