Hey HN! We're excited to share our new open-source project, Marvin. Marvin is a high-level library for building AI-powered software. We developed it to address the challenges of integrating LLMs into more traditional applications. One of the biggest issues is the fact that LLMs only deal with strings (and conversational strings at that), so using them to process structured data is especially difficult. Marvin introduces a new concept called AI Functions. These look and feel just like regular Python functions: you provide typed inputs, outputs, and docstrings. However, instead of relying on…

Hi HN! We just shipped a full-featured TUI (Text User Interface) for chatting with your Marvin bots, powered by GPT 4 or GPT-3.5. Like all of Marvin, it's fully open-source and we hope you find it useful. To launch it, upgrade and run `marvin chat`. The TUI is built with Textual (https://github.com/textualize/textual/) and uses some of its newest features including background workers and modals. We've made base TUIs before but this is the first one that's a true "app" with many screens and coordinated global state. Happy to answer any questions about working with…

Hey HN! We just released Marvin 2.0. Marvin is an AI toolkit for developers who want to use LLMs with traditional software. We still see significant challenges integrating LLMs because of how difficult it is to get them to reliably accept and return structured data. Marvin consists of independent, functional tools that address this problem in a variety of ways. Marvin has always been focused on using LLMs to work with native Python datatypes and Pydantic models. In 2.0 we've expanded this significantly with dedicated APIs for the most common use cases we've seen over the last year:…
