Hey Jose, author here! That's a great call out. I write predominantly in Swift and for a long time Claude was the only usable option. But sometime around GPT-5 OpenAI's models got much better at Swift, so the choice started becoming more about aesthetics (as a descriptor of preferences). So you're right — if the model can't write coherent code then it doesn't matter what kind of flow you feel as you're working with the tools — but I do imagine this will continue to improve for all languages including Elixir.
