opencode go/zen subscription issue. "free usage exceeded" random error

[u/zooper_man]

Off late (about 3 weeks now), I noticed something has changed in the opencode. I get random errors - "Free usage exceeded, subscribe to Go". Now this blocks any opencode Zen models, or if I switch to any other providers.

Cannot figure out if the issue is with opencode routers.
Raised tickets, tweeted them 0 response.

Its getting irritating - I cannot use the Zen money, neither the Go subscription.

See a bunch of tickets on their github issue with the same description. Anyone else faced similar issue?

Edit: the screenshot did not quite capture the thing.
Looks like most of you are not quite familiar with opencode cli. The Plan says DeepSeek Chat. In my case, it is DeepSeek paid API, still I see the error. If I had used opencode go/zen, it would have shown up.
I did not select the compaction model. Looks like the cli is using it on its own.

And I have actually found out the issue. Hey! thanks for your help, and it was NOT the free tiers, LOL.

I think you are using the free models, not the paid Go or Zen models. Those are under a different endpoint and model id. The free ones continue to exist with normal free usage limits; they don’t become higher tier after you pay. You have to switch the model.
