To the provider you select in the UI, I agree. But OpenCode automatically sends prompts to their free "Zen" proxy, even without choosing it in the UI.
Imagine someone using it at work, where they are only allowed to use a GitHub Copilot Business subscription (which is supported in OpenCode). Now they have sent proprietary code to a third party, and don't even know they're doing it.
The (relative) simplicity is what sells aider for me (it also helps that I use neovim in tmux).
It was easy to figure out exactly what it's sending to the LLM, and I like that it does one thing at a time. I want to babysit my LLMs and those "agentic" tools that go off and do dozens of things in a loop make me feel out of control.
