All OpenCode Zen free models blocked for three days — HTTP 429 on Windows #58900
Description
Hello OpenCode Support,
For the past three days, all free models available to me through OpenCode Zen have been blocked in the Windows desktop app. Switching between models does not help. Every attempt returns “Free usage exceeded, subscribe to Go,” followed by a long retry countdown.
This affects DeepSeek V4.1 Flash Free, MiMo V2.6 Flash Free, GLM-5.3 Flash Free, Beam Free, and other free Zen models.
The issue persists after upgrading OpenCode Desktop from version 1.18.31 to 1.19.4 and restarting the application. A previously configured local model gateway was removed, and OpenCode now connects directly to Zen. Windows proxy settings are disabled.
A diagnostic request using the official Desktop 1.19.4 bundled backend with an empty project returned:
- Time: October 25, 2026, 05:46:59 UTC
- Model tested: deepseek-v4.1-flash-free
- HTTP status: 429
- Error type: FreeUsageLimitError
- Message: “Free usage limit reached.”
- Retry-After: 65581 seconds, pointing to October 26, 2026, at 00:00 UTC
The local message history shows no successful Zen responses on October 24 or October 25 before this diagnostic test.
Could you please investigate why all free Zen models remain blocked? Is this an expected usage restriction, a shared-IP limit, or a quota-accounting issue? Please clarify which limit is being applied and how access can be restored.
I have attached a diagnostic report without API keys or passwords. Please let me know if you need additional details privately.
Thank you.

Thanks for the detailed report, @Gunkov. Being locked out of every free Zen model for three days, even after removing the gateway and connecting directly, is frustrating.
The
FreeUsageLimitError(HTTP 429, withRetry-Afterpointing to 00:00 UTC) is the Zen free-usage limit, which is enforced on the server for your account or connection. Only the team can check which limit is being applied and whether your usage was counted correctly. Billing and account support isn't handled in GitHub issues, so please email help@anoma.ly with the details: the timestamps, the model you tested and the diagnostic report you attached. If you've already emailed, the team will get to it, especially now that we've seen it here.Please keep email addresses, account identifiers, API keys and any payment details out of this public issue. Put them only in the email.

Same problem here. Windows, OpenCode Desktop v1.18.33.
"Free usage exceeded, subscribe to Go" plus a long retry countdown.

That is about 7h42m, which lands at 00:00 UTC. That matches the daily reset reported
in this issue, but the block continued afterwards.

Is this an expected limit, a per-IP limit, or a quota accounting problem? I am also
emailing help@anoma.ly.

Closing this now, since Zen free-usage limits and account questions are handled by email rather than in GitHub issues. @Gunkov, if your free models are still blocked or you want to know which limit is being applied, please email help@anoma.ly with your timestamps and diagnostic details. Please keep account identifiers, API keys and payment details out of this public issue. Thanks for the thorough report!

This is the third time my free usage limit has done this. The countdown keeps resetting to tens of thousands of seconds instead of actually resetting, and all free models return "429 Rejected" immediately. I've already waited for the limit to reset multiple times, but the same thing keeps happening. Is anyone else experiencing this? Is there an actual fix?
