Artificial Intelligence: Vector Embeddings
A blog post looking at what vector embeddings are, how to generate a vector embedding, and what a vector embedding looks like.
Mocking (Python)
When I write code I like to include tests. Tests help me to reduce the risk of code breaking changes and give me the reassurance that what I have coded does what I need it to do. I’m currently writing a backend (Django/Python) that serves some APIs and a frontend (Flask/Python) to consume those APIs, […]
LLM – Retrieval Augmented Generation (RAG) with Ollama Embeddings
The work on the Large Language Model (LLM) bot so far has seen the running of LLM locally using Ollama, a switch in models (from tinyllama to gemma) whilst introducing LangChain and then the switch to LangChain templates. Note: If you skipped the previous blog entry posts, I’m following along with Real Pythons “Build an LLM […]
LLM – Langchain Templates (Python)
I finished my previous blog post with the aim of looking at Langchain’s template options. I feel like I was on a similar path during my last post, with defining the initial prompt to be passed each time. However, the Langchain templates allow for easier and more thorough control. Langchain keeps the prompts and model […]

Installing a local Large Language Model (LLM) with Ollama
Large Language Models (LLMs) such as ChatGPT have gained a lot of traction over the last year or two, and more tech companies are looking to include artificial intelligence (AI) in their products via LLMs. This includes Apple with their Apple Intelligence in iOS and MacOS which can be expanded with ChatGPT, and Microsoft with […]
Vue.JS, Django, GraphQL API and more!
On a recent visit to Real Python (www.realpython.com) I came across a course aiming to show how to create a blog with a Django (Python) backend and a Vue.JS (JavasScript) frontend, with the frontend and backend using GraphQL to share data. I’ve not utilised GraphQL or Vue.JS in a project before so I decided to […]
