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…

x402▲119Hi HN – excited to announce x402, initially developed by Coinbase (YC 12) x402 lets any HTTP API charge per request without issuing API keys or storing credit cards. Buyers (humans or AI agents) keep funds in their own wallet and dynamically discover compatible endpoints, call them as usual, and automatically pay a microtransaction in USDC or other tokens to settle. 90 second demo: https://www.youtube.com/watch?v=PV-L2AfLhJg Problem: Every time we want to use a new API we have to: find the service online create a developer account, copy a secret key into env vars, pre-fund or…

Hi all, I wanted a robust way to keep track of my receipts without needing to keep them in a box and so i found paperless - but the existing paperless ai projects didn't really convert my receipts to usable data. so I created a fork of nutlope's receipthero (actually it's a complete rewrite, the only thing that remains over is the system prompt) The goal of this project is to be a one stop shop for automatically detecting tagged docs and converting them to json using schema definitions - that includes invoices, .... i can't think of any others right now, maybe you can? If you do please make…

I want to get feedback on a project I've been working on to reduce the boilerplate involved in "productizing" a site. Over the past few years I've built a number of small tools or sites that I wanted to try to monetize, and each time I found that, despite their excellent APIs and documentation, integrating with auth and payment providers can take several days (or weekends in my case). This can have a big chilling effect and certainly distracts me from improving the actual product. There is prior art in this space, in particular the fantastic OAuth2-Proxy [1] which is a self-hosted solution…
