I wouldn't trust OpenCode Go with my lunch after the shit-sandwich they served us with horrible V4 quants and 0 transparency. Then blaming it on their partners.
a month of opencode go is cheaper than lunch, so trusting them with this but not your lunch seems reasonable.
I'm an OpenCode Zen user and I picked it over Go because opencode actually hosts those models and can make assurances about how the data is handled. OpenCode Go is a subsidized service that sends all of your data out to third-party providers, and then your data is subject to whatever terms they have.
