TypeChat is an open source library developed by Microsoft that simplifies the creation of natural language interfaces by using type definitions to structure interactions with large language models. Traditional natural language interfaces often relied on complex decision trees to interpret user intent and gather required inputs. With the rise of large language models, developers can interpret user requests more easily, but they still face challenges related to output reliability, safety, and structured responses. TypeChat addresses these challenges by replacing traditional prompt engineering with a concept called schema engineering. Instead of writing complex prompts, developers define types that represent the intents supported by their applications. It then uses those type definitions to construct prompts for language models and translate user input into structured data that follows the defined schema.
Features
- Converts natural language input into structured data defined by type schemas
- Replaces prompt engineering with schema-based development using types
- Automatically constructs prompts for language models from defined schemas
- Validates language model outputs to ensure they match expected structures
- Repairs invalid responses through additional model interactions
- Produces type-safe structured results that applications can directly process
