Z.ai coding model connection issue

Question

OS Ubuntu 22.04.5 LTS
opencode ver. 1.0.65

Hello! I have an issue in Z.ai model using in opencode. I have an Z.ai API-key. It is added to opencode by *auth login * command. Access to model works okey when I make request by curl:

curl -X POST "https://api.z.ai/api/coding/paas/v4/chat/completions" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer  my api-key" \
-d '{
  "model": "glm-4.6",
  "messages": [{"role": "user", "content": "Write a short story about a robot"}],
  "stream": true
}'

request and answer log:

 curl -X POST "https://api.z.ai/api/coding/paas/v4/chat/completions" \ST "https://api.z.ai/api/coding/paas/v4/chat/completions" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer 6ebc214feae84a9899e35a5726930070.eeVimJD98DJYlxm2" \
-d '{
  "model": "glm-4.6",
  "messages": [{"role": "user", "content": "say Hello!"}],
  "stream": true
}'
data: {"id":"2025111517384495eaf2ee418443b1","created":1763199524,"model":"glm-4.6","choices":[{"index":0,"delta":{"role":"assistant","content":"","reasoning_content":"\n"}}]}

But when I try to send request from opencode it finishes by timeout after long waiting.

debug log print looks like:

How to fix this issue?

Best regards,

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

OpenCode v1.0.25 Hangs Indefinitely with LM Studio + Qwen Models Due to Empty tool_calls Array #4255: Very similar indefinite hanging issue with detailed root cause analysis pointing to tool calling problems
No Response Requested #2892: GLM 4.6 timeout/hanging issue where users get stuck on generating with no code
have error with tool call from 1.0.62 build ( current 1.0.65 still have this issue ) #4322: Z.ai Coding Plan GLM 4.6 with tool calling issues since v1.0.62

The core issue appears to be related to improper handling of empty tool_calls: [] arrays that some providers (including Z.ai) include in responses, causing OpenCode to hang indefinitely.

Feel free to ignore if none of these address your specific case.

Addition to opencode.json "tools" fieild:

"tools": {
    "bash": false,
    "read": false,
    "write": false,
    "edit": false,
    "glob": false,
    "grep": false,
    "list": false,
    "todoread": false,
    "todowrite": false,
    "webfetch": false,
    "task": false
  }

Fixes connection. But maybe cuts functionality.

Try using the z.ai coding plan instead, it has its own auth method in opencode.

@chetverovod

@chetverovod add this to your opencode.json:

{
 "provider": {
   "zai-coding-plan": {
     "options": {
       "timeout": 600000
     }
   }
 }
}

This will override default timeout for the provider and set it to 10 minutes (timeout is in milliseconds)

The fetch automatically times out if there is no data being sent from the server at all, as long as data is being sent the connection won't timeout

Try using the z.ai coding plan instead, it has its own auth method in opencode.

The z.ai coding plan doesn't work with OpenCode in VS Code extension, although it works in the terminal.

@mossbergmaverick

@mossbergmaverick hm that doesn't make sense, is it the oauth flow not going through properly? The vscode extension just launches the tui

@mossbergmaverick hm that doesn't make sense, is it the oauth flow not going through properly? The vscode extension just launches the tui

I'll describe in more detail what I mean:
I opened VSCode and launched it through the extension (I have Sonnet 4.5 as the main agent and GLM 4.6 as a sub-agent, to which tasks are delegated). I asked the agent to pass a task to the sub-agent to create a test text file in the project root. Nothing happened - the model looks like it froze. However, if I connect GLM directly and interact with it, it responds.
I just rechecked, and the problem is that GLM should request permission for write and edit operations, but the confirmation dialog doesn't appear on my end. I thought the model had simply frozen. But as I understand it now, this is related to my issue - meaning not only does ESC not work, but the confirmation dialog for executing actions is also missing.
If you need me to take any specific steps to clarify the situation, I'm ready to help.

@chetverovod add this to your opencode.json:
{
 "provider": {
   "zai-coding-plan": {
     "options": {
       "timeout": 600000
     }
   }
 }
}
This will override default timeout for the provider and set it to 10 minutes (timeout is in milliseconds)

Hello, now for opencode.json:

 {
     "$schema": "https://opencode.ai/config.json",
     "provider": {
         "zai-coding-plan": {
             "options": {
                 "timeout": 600000
             }
         }
     }
 }

I had got timeout after 10 minutes:

@chetverovod

@chetverovod you can continue bumping the timeout to higher values, we can consider changing the default too I suppose

oh u can disable the timeout too using

timeout: false

@mossbergmaverick

@mossbergmaverick ill check it out

timeout: false does not change result.

if you set timeout to false and restart opencode (because settings arent hot reloaded rn) it disables the fetch timeout entirely is that not happening for u?

Fetch timeout is entirely disabled if used timeout: false.

yes

I see this, opencode now does not generate timeouts. But dialog with Z.ai does not work.
