Description

Using gpt-5.2-codex via azure gives error:

The chatCompletion operation does not work with the specified model, gpt-5.2-codex. Please choose different model and try again. You can learn more about which models can be used with each operation here: https://go.microsoft.com/fwlink/?linkid=2197993.

model gpt-5.2 works fine

used opencode, to fetch opencode source, add debug, identify issue and fix

issue is
`@ai-sdk/azure does support the Responses API. The issue is in opencode’s routing: your custom azure-openai provider goes through the generic path, which defaults to chat-completions unless useCompletionUrls is set. That’s why it’s hitting /chat/completions even though the model supports responses'

Plugins

nada

OpenCode version

latest - dev branch

Steps to reproduce

  1. use custom provider via @ai-sdk/azure
  2. set model to gpt-5.2-codex
  3. launch opencode

using azure as providerId instead of azure-openai resolves the issue

I'm having the same problem. I'm trying to use gpt-5.1-codex and it works when I run opencode on my local machine, but when I try to run it on a gitlab ci pipeline with the same configurations (same opencode.jsonc and variables) it always fails with the error The chatCompletion operation does not work with the specified model, gpt-5.1-codex. Please choose different model and try again. You can learn more about which models can be used with each operation here: https://go.microsoft.com/fwlink/?linkid=2197993. I tried with opencode versions 1.1.23 and 1.1.26. This is the opencode.jsonc I am using

{
  "$schema": "https://opencode.ai/config.json",
  "model": "azure/gpt-5.1-codex",
  "provider": {
    "azure": {
      "options": {
        "apiKey": "{env:AZURE_OPENAI_API_KEY}",
        "resourceName": "{env:AZURE_OPENAI_RESOURCE_NAME}",
      },
      "models": {
        "gpt-5.1-codex": {
          "name": "gpt-5.1-codex",
          "id": "{env:AZURE_OPENAI_DEPLOYMENT_NAME}"
        }
      }
    }
  }
}

I also added the useCompletionUrls option to false but didn't make any difference, it always resolve to the chatCompletion.

Can you please help me? Thank you in advance
