The buzz and excitement around generative AI is continuing to grow as their capabilities rapidly expand. However, their ability to generate content is just the starting point. From my perspective, the emergent reasoning capability, coupled with their intelligent use of tools, is what will make this technology truly transformational, and will mark the start of a new technology epoch.
Artificial Intelligence
It is quite common for blogs, or news / content distribution websites, to organise their content around categories of tags. However, this approach is time-consuming, and from measuring behaviours, it doesn't seem to do much to encourage browsing. In this blog post I use the new OpenAI embedding API to create highly targeted article recommendations, resulting in a four-fold (x4) increase in engagement.

Last month GitHub released Copilot, an AI powered tool that provides surprising accurate suggestions ranging from a few lines of code to entire functions. Copilot uses a vast and powerful AI model that is trained on billions of lines of open source code from GitHub. This, combined with the context provided by your code and comments, allows it to provide amazingly accurate suggestions. This is no simple autocomplete, this is pair programming with a robot!
Artificial Intelligence
I've been lucky enough to be granted access to the preview of Copilot, GitHub's new 'AI pair programmer' that is causing quite a stir. This blog post shares my initial thoughts and experiences with this tool. In brief, I'm stunned by its capabilities. It has genuinely made me say 'wow' out loud a few times in the past few hours, not something you expect from your developer tooling.
