There is Microsoft Copilot, which replaced Bing Chat, Cortana and uses OpenAI’s GPT-4 and 5 models.
There is Github Copilot, the coding autocomplete tool.
There is Microsoft 365 Copilot, what they now call Office with built in GenAI stuff.
There is also a Copilot cli that lets you use whatever agent/model backend you want too?
Everything is Copilot. Laptops sell with Copilot buttons now.
It is not immediately clear what version of Copilot someone is talking about. 99% of my experience is with the Office and it 100% fails to do the thing it was advertised to do 2 years ago when work initially got the subscription. Point it a SharePoint/OneDrive location, a handful of excel spreadsheets and pdfs/word docs and tell it to make a PowerPoint presentation based on that information.
It cannot do this. It will spit out nonsense. You have to hold it by the hand tell it everything to do step by step to the point that making the PowerPoint presentation yourself is significantly faster because you don’t have to type out a bunch of prompts and edit it’s garbage output.
And now it’s clear they aren’t even dogfooding their own LLM products so why should anyone pay for Copilot?
I was trying to just get an Excel function dialed in with some IFs and formatting weirdness. The licensed Microsoft 365 Copilot built into Excel tried several times and failed miserably. One screenshot to ChatGPT (5.1?) and it was one-shot.
I'm not even sure it's the same models any more. It feels years behind. Maybe they limit it or cripple it somehow.
