One of the most common questions I get asked is: “Which AI model should I be using with GitHub Copilot?”

Open GitHub Copilot today and you are greeted with a dropdown menu that looks like a wine list. Sonnet? Gemini? Opus? GPT-5? 🤯 It used to be simple, but now it can be paralysing.

Which one is best? It depends on what you are trying to achieve, how complex the task is, and how you want to manage your credit usage.

My rule of thumb is simple:

• Start cheap to think and iterate.
• Pay for certainty when the blast radius is big.

Voice assistants used to be simple, reliable helpers. Well, maybe not truly reliable. They weren’t perfect, but for years, you could count on them to set a reminder, add a calendar event, or play your favourite playlist. They quietly made life easier, even if they never lived up to the sci-fi hype.
