Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…

Just a simple tool I hacked together last night. I wanted to paste a bunch of JSON for reference in an IRC channel, but the JSON that I wanted to paste was not formatted. I didn't quickly find a pastebin that formatted JSON for me so I just made one. It's probably so simple that it's borderline useless, but here it is! http://jsonifier.com/ example output: http://jsonifier.com/paste/4e3f84b46f3b792dde000000

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!

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,…
