guidance

You can enforce structured JSON output by applying regex constraints and grammar-based generation to ensure the response strictly matches your defined format. This prevents parsing errors and guarantees valid JSON, XML, or code generation.

Yes, you can build multi-step LLM workflows using Pythonic control flow to orchestrate complex generation sequences. This allows you to chain language model calls and intermediate logic seamlessly within standard Python scripts.

Yes, you need the guidance library and Python installed to run constrained generation capabilities for LLMs. This environment provides the necessary framework for applying grammar rules and regex patterns to model outputs.

Constrained generation works with llama.cpp and transformers as underlying dependencies for executing grammar-based rules. This integration ensures that regex pattern matching and structural constraints apply directly across these model frameworks.

The best way to generate valid structured data formats from user input is to define the exact structure and constraints before generation. Grammar-based generation enforces these rules during decoding, ensuring accuracy and consistency in the output.
