 > **Attribution**: This library is developed based on the approach and methodology from [OpenAI's Node.js library](https://github.com/openai/openai-node), which itself vendors the [Promplate partial-json-parser-js](https://github.com/promplate/partial-json-parser-js) library. The test cases and parsing strategies are adapted from both the original @promplate implementation and @OpenAI's usage of it, ported to Swift with additional Swift-specific optimizations.
 > 
 > Special thanks to the @Promplate team for creating [the original partial JSON parsing solution](https://github.com/promplate/partial-json-parser-js) that inspired this Swift implementation.
