I've done a handful of fun hardware + LLM projects...

* I built a real life Pokedex to recognize Pokemon [video] https://www.youtube.com/watch?v=wVcerPofkE0

* I used ChatGPT to filter nice comments and print them in my office [video] https://www.youtube.com/watch?v=AonMzGUN9gQ

* I built a general purpose chat assistant into an old intercom [video] https://www.youtube.com/watch?v=-zDdpeTdv84

Again, nothing terribly useful, but all fun.

I'm building a weight-loss app that leverages LLM to do 2 things: 1. Analyze calories/macronutrients from a text description or photo 2. Provide onboarding/feedback/conversations like you'd get from a nutritionist https://www.fatgpt.ai/ My stack is Ruby on Rails, PostgreSQL, OpenAI APIs. I chose Rails because I'm very fast in it, but I've found the combination of Rails+Sidekiq+ActionCable is really nice for building…

Jokes aside, GPT-4 Vision is surprisingly good at noticing facts from food images. For example:

- In my chipotle bowl, it can tell if I had brown rice vs white rice

- In my In-n-out, it can tell if I got it protein style

It struggles with accurate weights/volumes but I'm excited about where this is going.

We built Jumprun. You can use it to research and analyze data sources, and it'll produce beautiful canvases with tables, charts, videos, maps, etc. We're working on automations so you can setup natural language trigger conditions that execute actions. We built it in Kotlin with Ktor server, htmx and tailwind. It uses a mixture of models, including gpt4-turbo, gpt4-vision and gemini-pro-vision. It's deployed using Kam…

Cool! I like the "intelligent canvas" concept. Not exactly the same but my brother and I have been building a side project that also is all about making the most of a set of information using different views like maps, calendars, tables, etc. We have been looking into adding AI to make it easier to import data without having to manually tag all the data. https://visible.page

I have built a webapp for translating srt files: https://www.subsgpt.com GPT-4 excels as a translator, but it often encounters issues with content warnings and formatting errors when translating entire subtitle files via ChatGPT. The solution is straightforward: divide the subtitle file into sections, focusing solely on translating the text and disregarding the timestamps. While it's feasible to have ChatGPT maintain…

This is great, how well does it do with informal/slang Portuguese, Russian or Spanish?

I've built a sales bot that would go over a predefined sales scenario like a real human would, being able to jump between steps and work with any complications real conversation would throw at it. It would appear fully human to whoever converted with it. Unfortunately, it was never deployed in production due to business reasons.

fatGPT... the LLM that helps you be more model, less large.

It's macro + calorie tracking over text message. You just text what you eat and it matches against a food database to estimate your food intake. It's basically an easier alternative to MyFitnessPal.

My stack is OpenAI on Azure, Vercel, Convoy, FatSecret API, Postmark, NextJS.

I was holding a free screening of a short film I made, and as an alternative to Eventbrite and the like, I built a simple SMS-based ticket reservation system that used GPT-4 to read and respond to messages. People interested in attending would text a number and their messages were routed by Twilio to my Node.js app, which in turn sent them to GPT to generate a response. The LLM was instructed to provide a structured JSON of each reservation once the person gave their name and the number of the seats they wanted. Worked very smoothly and only took an afternoon to build. Would've been infinitely more tedious if I had to worry about parsing messages with my own code.

I was working on this stuff before it was cool, so in the sense of the precursor to LLMs (and sometimes supporting LLMs still) I've built many things:

1. Games you can play with word2vec or related models (could be drop in replaced with sentence transformer). It's crazy that this is 5 years old now: https://github.com/Hellisotherpeople/Language-games

2. "Constrained Text Generation Studio" - A research project I wrote when I was trying to solve LLM's inability to follow syntactic, phonetic, or semantic constraints: https://github.com/Hellisotherpeople/Constrained-Text-Genera...

3. DebateKG - A bunch of "Semantic Knowledge Graphs" built on my pet debate evidence dataset (LLM backed embeddings indexes synchronized with a graphDB and a sqlDB via txtai). Can create compelling policy debate cases https://github.com/Hellisotherpeople/DebateKG

4. My failed attempt at a good extractive summarizer. My life work is dedicated to one day solving the problems I tried to fix with this project: https://github.com/Hellisotherpeople/CX_DB8

request - i want an LLM tool that can process raw text or email and update or create salesforce records. Example 1: i get an email from a potential customer that says they want [product A]. I can forward that email (or call notes) to salesforce (or somewhere) and it will understand the preference and the relevant customer and update that customer's profile. Example 2: In a B2B context, lets say my customer is a compa…

I'm working on something like that. Feel free to email me (address in my bio).
