   Potential fix/workaround: I was running opencode in keyless mode (no login). All other free models worked, but deepseek-v4-flash-free kept failing with 'Upstream request failed: Endpoint is unavailable.' I created a fresh API key from the OpenCode Zen dashboard, connected with that key instead of keyless mode, and everything works now. Suspect keyless/anonymous Zen requests get deprioritized or routed differently on the free DeepSeek lane.

   Closing: "Upstream request failed: Endpoint is unavailable" was a temporary gateway outage around Aug 15-17 that has since been resolved. If you still see it on the latest version, please open a new issue with the model and time of the failure. Some cases were caused by the console privacy region setting (Settings → Privacy), so check that too.
