A couple of experiments today: I completed a simple tutorial that helps you build a RAG app using local models. I also installed and tested https://openwebui.com/. This is a really cool open source project that gives you a ChatGPT-style interface to use with large language models that run

I’ve just finished listening to this podcast with the founders of https://www.factory.ai/. Their startup automates away the drudgery bits of work in software engineering. That includes writing tests, debugging, documentation, and migrations. I found the views of the founders compelling. For example, they don’t think

I finally have a Youtube video summarizer working! I’ve deployed the app with Streamlit.io. On the backend I’m using the Gemini 1.5 Flash LLM because it’s cheap and fast! The summaries are “chained” together using Langchain. A 20 minute video can be summarized in around

I’ve been testing out the new Claude LLM and it’s better at coding than GPT4o. I might actually start using it more given how fast and effective it is. You can see the benchmarks below that Anthropic provided. They probably have some bias as they are self-published but

Today I got a Youtube summarizer script working! I can input a Youtube URL and I get useful summary of the video using the Langchain “refine” documents chain. I really like this because iterates over portions of text and it refines the summary until something more thorough is generated. I’

This evening I experimented with Langchain’s summarisation frameworks. This is something LLMs are great at natively, but with Langchain, you can use even more sophisticated summarisation techniques. Here’s a GPT-generated summary of these techniques based on the Langchain documentation: From ChatGPT4o: 1. Stuff Method * Concept: Simply concatenate all

Given the note I wrote yesterday about the need to be “programmatically” lazy, I’m rewriting my Youtube reviewer system. I’m building it initially without agents, and I’ll only add an agentic layer in areas that are more unstructured. I’m not yet sure what areas will have

The temptation with any new powerful tool is to apply it in more places than is necessary. What’s that saying…”to a man with a hammer, every problem is a nail”? The same appears to be happening with large language model frameworks and AI agent frameworks. I’ve experienced

One of the pioneers of how large language models are trained and fine-tuned, Jeremy Howard, has a great article here on “What policy makers need to know about AI (and what goes wrong if they don’t)”. The article is actually very accessible to everyday readers. Here’s an excerpt

I tested out a few AI agents today with the goal of optimising on cost, but they remain expensive to run if you have tasks that involve multi-step reasoning with chunky bits of content. One group of tasks that I gave to GPT4o cost $0.15 and took 2 minutes

OpenAI launched a feature called “function calling” last year, but it’s a feature I haven’t used and didn’t understand until today. Part of my misunderstanding was because the feature is poorly named. It made me (and many other more technical people) expect that the capability means an

I have a 7 billion parameter large language model running locally on my Macbook thanks to Ollama! This is great when travelling and there’s no Wifi to access ChatGPT or other large language models. What I can run on my Macbook today is not as powerful as GPT4o but
