    Anything To JSON – a language model for structured extraction▲18

    Hey HN! Erik here from banana.dev We’ve trained a small(ish) language model on structured extraction, and today we’re launching a playground for it at https://anythingtojson.com. Give it a try! This model continues our work on structured generation, following last week’s launch of Fructose[1], a python client for strongly-typed LLM responses. There seem to be two distinct halves of the problem intended to be solved by Fructose and structured generation: 1. the reasoning ability of the model, such as performing chain of thought, creative acts, and natural language tasks. In a way,…

    I made a tool to easily transform and manipulate your JSON data▲5

    Hey NN, I've create a tool that allows you to easily manipulate and transform json data. After looking round for something to allow me to perform json to json transformations I couldn't find any easy to use tools or libraries that offered this sort of functionality without requiring learning obscure syntax adding unnecessary complexity to my work or the alternative being manual changes often resulting in lots of errors or bugs. This is why I built JSON Transformer in the hope it will make these sort of tasks as simple as they should be. Would love to get your thoughts and feedback you have…
