Custom OpenAI Compatible model configuration not showing up in Model Selector via chatLanguageModels.json

[marionngu]

Describe the bug
I am trying to configure a custom OpenAI Compatible provider (GLM-4.7 via Zhipu/Custom endpoint) by editing the chatLanguageModels.json file. However, after saving the configuration and reloading the window, the custom model does not appear in the Language Models list, and I cannot select it.

To Reproduce

Open VS Code Insiders.
Navigate to User/chatLanguageModels.json.
Add the following configuration:
[
{
"name": "OpenAI Compatible",
"vendor": "customoai",
"family": "glm-4",
"version": "4.7",
"id": "glm-4.7",
"maxInputTokens": 204800,
"endpoint": "https://api.z.ai/api/coding/paas/v4",
"apiKey": "${input:chat.lm.secret.TOKEN}",
"model": "glm-4.7"
}
]

Save the file and run "Developer: Reload Window".
Open the Language Models tab or Chat interface.
Attempt to search for "OpenAI Compatible" or "glm-4.7".

Expected behavior
The custom model should appear in the selection list and be available for chat.

The configuration seems to be wrong. It should be following

[
       {
		"name": "OpenAI Compatible",
		"vendor": "customoai",
		"apiKey": "${input:chat.lm.secret.TOKEN}",
		"models": [
			{
				"name": "GPT 4o",
				"id": "gpt-4o-1120",
				"url": "https://api.z.ai/api/coding/paas/v4",
				"toolCalling": true,
				"vision": true,
				"thinking": true,
				"maxInputTokens": 64000,
				"maxOutputTokens": 16000

			}
		]
	}
]

Also the current insiders is not showing intellisense to add models in the file. This will be fixed in next insiders. You should add all necessary properties for each model. You have to use the configure action on the "OpenAI Compatible" entry in the editor to update the api key

Sandeep Somavarapu (@sandy081) this is not true! I can confirm that issue is still present. I have latest insider version, identical configuration and model list is empty

Petr Plenkov (@ThePlenkov) Can you please share the content of your chatLanguageModels.json file?
