Iterative Summarization using LLMs

After being busy for the first part of the year, I finally have a bit of time to work on this blog. After a lot of thinking about how to best fit it into my schedule, I've decided to attempt to write shorter posts. Although I do get a lot of satisfaction writing long posts, it's not practical because of the time commitment. Better to break it up into smaller parts to be able to "ship" often rather than perfect each post. This also allows me to experiment with smaller scoped topics, which hopefully will keep more more motivated as well. Speaking of which...

This post is about answering a random thought I had the other day: what would happen if I kept passing an LLM's output back to itself? I ran a few experiments of trying to get the LLM to iteratively summarize or rephrase a piece of text and the results are... pretty much what you would expect. But if you don't know what to expect, then read on and find out what happened!

LLM Fun: Building a Q&A Bot of Myself

Unless you've been living under a rock, you've probably heard of large language models (LLM) such as ChatGPT or Bard. I'm not one for riding a hype train but I do think LLMs are here to stay and either are going to have an impact as big as mobile as an interface (my current best guess) or perhaps something as big as the Internet itself. In either case, it behooves me to do a bit more investigation into this popular trend 1. At the same time, there are a bunch of other developer technologies that I've been wondering about like serverless computing, modern dev tools, and LLM-based code assistants, so I thought why not kill multiple birds with one stone.

This post is going to describe how I built a question and answering bot of myself using LLMs as well as my experience using the relevant developer tools such as ChatGPT, Github Copilot, Cloudflare workers, and a couple of other related ones. I start out with my motivation for doing this project, some brief background on the technologies, a description of how I built everything including some evaluation on LLM outputs, and finally some commentary. This post is a lot less heavy on the math as compared to my previous ones but it still has some good stuff so read on!
