[Bug] OpenCode Go: return 401 Request blocked by upstream provider — chat/completions blocked while /v1/models works

[lizijiangyyjx]

Description

Starting today (2026-07-22), all models under my OpenCode Go subscription are returning 401 Request blocked by upstream provider when calling the chat/completions endpoint. The /v1/models endpoint works fine.

This appears to be a server-side issue affecting Go subscriptions, not a client configuration problem.

Account Details

• Subscription: OpenCode Go
• Expiry: 2026-08-13
• Console status: All usage limits (5h / weekly / monthly) show sufficient balance
• API Key: Valid (tested with newly created key, same result)

Affected Models

All of the following models return the same error:

Model	Result
deepseek-v4-flash	❌ 401
kimi-k2.6	❌ 401
glm-5.2	❌ 401
mimo-v2.5	❌ 401

Reproduction Steps

Step 1: List models (works)

curl -H "Authorization: Bearer $OPENCODE_API_KEY" \
  https://opencode.ai/zen/go/v1/models

Result: 200 OK — returns full model list including all 4 models above.

Step 2: Chat completion (fails)

curl -X POST https://opencode.ai/zen/go/v1/chat/completions \
  -H "Authorization: Bearer $OPENCODE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"deepseek-v4-flash","messages":[{"role":"user","content":"hello"}]}'

Result:

{"type":"error","error":{"type":"AuthError","message":"Request blocked by upstream provider."}}

What I've Verified

• API Key is valid and active
• Base URL is correct (https://opencode.ai/zen/go/v1)
• Tested directly with curl to eliminate client-side issues
• Created a brand new API Key — same result
• All models affected, not just one
• Console shows sufficient usage quota remaining

Related Issues

Possibly related to #21097 and #20984 which report similar symptoms.

Expected Behavior

chat/completions should return a valid response when the API Key is valid, subscription is active, and usage quotas are not exceeded.

Actual Behavior

All chat/completions requests return 401 Request blocked by upstream provider, while GET /v1/models works fine with the same key.

This issue might be a duplicate of existing issues. Please check:

• 401 AuthError: Request blocked by upstream provider #38195: 401 AuthError: Request blocked by upstream provider
• bug(opencode-go): All subscription models return "Request blocked by upstream provider" #38218: All subscription models return "Request blocked by upstream provider" (OpenCode Go)

These issues report the same symptom — chat/completions returning 401 Request blocked by upstream provider while /v1/models works fine — for Go subscription users starting today.

目前看来是 opencode 的模型服务提供有问题了。只能等官方解决了

Is it possible that the account has been disabled? I noticed that this issue doesn’t occur in all accounts.
是不是账号被禁用了？我发现并非所有账号都出现这个问题

看起来不像是账号禁用的问题。opencode 不像 anthropic 和 OpenAI 属于商业 AI 范畴，禁用账号是出于政策原因。我身边也有朋友是订阅了 GO 还正常能用的，现在还不完全知道问题所在

看起来不是账号取消的问题。opencode 不是 anthropic 和 OpenAI 属于商业 AI 星球，取消账号是因为政策原因。我身边也有朋友是订阅了 GO 还能正常用的，现在完全不知道问题在哪里

我看有很多人提这个问题，但是我现在还没有看到解决方法或者是原因，我甚至不知道是不是我账号的原因

别怀疑自己，这大面积的 401.一定是服务商有问题了

看起来不像是ban账号，我看有人说他支付宝支付的也401了

现在官方也没出来回应，也不知道想干什么，目前网上关于这个报错的信息就那几个文章

没办法的事，歪果仁的服务意识真的很一般
