Guidance is an open-source library developed by Microsoft designed to precisely control how an LLM generates text. If you have ever been frustrated by AI responding with malformed JSON or adding conversational filler that breaks program logic, this tool is the solution. Guidance works by constraining the AI model at the token level to adhere to structures or specific wording you define from the start.
For game developers, this level of control is essential. When integrating LLMs into a game to create dynamic NPC dialogue or generate game state updates, AI outputs must be 100% consistent to prevent engine crashes. Guidance ensures the AI only produces responses in formats that can reliably be parsed by your system, making generative AI integration into game mechanics far safer and more dependable.
How to get started:
- Open your terminal and install the library into your environment by running the command “pip install guidance”.
- Create a new Python script in your code editor and connect the library to your chosen language model (supporting both local model execution and external APIs).
- Structure your prompt using Guidance’s built-in templating to lock in mandatory text elements, forcing the LLM to only fill in the specific data variables you request.
