SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Generating structured data like JSON, XML, or code from large language models often produces invalid, malformed, or schema-non-compliant outputs that cause failed integrations, require endless retry loops, and demand hours of manual post-processing to correct.

Core Features & Use Cases

  • Guaranteed schema compliance: Constrain token generation at the logit level using finite state machines to ensure all outputs match JSON schemas, Pydantic models, regex patterns, or code syntax, eliminating invalid results entirely.
  • Local model support: Natively integrates with Transformers, llama.cpp, and vLLM backends for high-speed, private inference on your own hardware with no reliance on external API providers.
  • Real-world use case: Extract structured customer data from unstructured support tickets, generate type-safe API request payloads, or produce syntactically correct code snippets that align with your project's requirements in seconds.

Quick Start

Use the outlines skill to extract a customer's full name, email address, and support ticket category from the unstructured support message provided and return the data as a valid Pydantic SupportTicket model instance.

FAQPage Schema
How do I guarantee valid JSON schema outputs when generating text with local LLMs?

You can guarantee valid JSON schema outputs by enforcing schema constraints directly at the token level using finite state machines. This ensures all generated text from local LLMs perfectly matches your Pydantic models, eliminating malformed results without post-processing.

What's the best way to generate structured data from unstructured text using vLLM?

The best way to generate structured data using vLLM is applying grammar-based token sampling control. This constrains model outputs during inference, allowing you to extract type-safe data like customer support tickets directly into valid schemas with zero overhead.

Does grammar-based generation slow down inference speed on local model backends?

Grammar-based generation does not slow down inference speed on local model backends. It applies zero-overhead logit-level constraints during token sampling, ensuring production-grade performance while maintaining guaranteed schema compliance across Transformers, llama.cpp, and vLLM.

Can I use Pydantic models to enforce constraints on llama.cpp generated outputs?

Yes, you can use Pydantic models to enforce constraints on llama.cpp generated outputs. The system natively integrates with local backends like llama.cpp to map Pydantic models into finite state machines for reliable, syntax-constrained text generation.

How do I extract type-safe API request payloads from unstructured documents using Transformers?

To extract type-safe API request payloads from unstructured documents using Transformers, apply schema constraints during generation. This maps your desired payload structure into a finite state machine, guaranteeing the model produces syntactically correct and schema-compliant data.

Why do large language models produce invalid JSON when parsing complex schemas?

Large language models produce invalid JSON when parsing complex schemas because standard token sampling lacks structural constraints. Without grammar-based generation, the model freely samples tokens that violate schema rules, causing failed integrations and requiring endless retry loops.
