SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates the production of strictly structured outputs (JSON/XML/code) to minimize post-processing errors and enable reliable downstream processing in automation pipelines.

Core Features & Use Cases

  • Ensures generated artifacts adhere to JSON/XML schemas or code structure.
  • Uses Pydantic models for type-safe outputs and supports local-model backends (Transformers, vLLM) for private deployments.
  • Use cases include data extraction pipelines, API contract generation, and automated reporting with deterministic formatting.

Quick Start

Create a JSON schema for a user profile with fields name, email, and age.

FAQPage Schema
How do I guarantee valid JSON structure during local model generation?

FSM-based structured generation enforces valid JSON structure during local model generation by constraining the output token by token. This approach uses Pydantic models for type-safe outputs and supports local backends like Transformers and vLLM.

What is the best way to generate structured outputs for data extraction pipelines?

Using Pydantic models to define expected schemas is the best way to generate structured outputs for data extraction pipelines. This ensures artifacts strictly adhere to JSON or XML schemas, minimizing post-processing errors and enabling reliable downstream processing.

Can I use vLLM for structured generation with private local deployments?

Yes, you can use vLLM for structured generation with private local deployments. The system explicitly supports local backends like vLLM and Transformers, allowing you to maximize inference speed while maintaining type-safe structured outputs in isolated environments.

Does Pydantic model integration work for generating XML schemas?

Yes, Pydantic model integration works for generating XML schemas. The system ensures generated artifacts adhere to specified XML schemas or code structures, automating the production of strictly structured outputs for deterministic formatting and downstream automation.

Why does FSM-based structured generation maximize inference speed?

FSM-based structured generation maximizes inference speed by using a finite state machine to constrain valid tokens during the generation process. This prevents invalid sequences from being computed, accelerating inference while guaranteeing valid JSON or XML outputs.
