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.
This is exactly me considering what I might have leaked to god knows who via grok. I was hyped by opencode but now I’m thinking of alternatives. A huge red flag… at best irresponsible?
