🐛 Bug Description

Option Displays ‘undefined’

• When using the DEFAULT_MODEL environment variable to set the default model to gpt-3.5, the model option displays as undefined. Despite this, the functionality remains operational.

The title of the automatic follow-up request is incorrect after the initial request. This issue occurs because the model is switched to gpt-3.5-turbo.

have a try with gpt-3.5@openai

have a try with gpt-3.5@openai

This looks no different.

By the way, gpt-3.5@openai seems like a custom model. Are you referring to the CUSTOM_MODELS environment variable?
Actually, DEFAULT_MODEL does not support this syntax.

#4921 应该和这个是一个问题，好像是最近版本更新导致的

#4921 should be a problem with this, it seems to be caused by the recent version update

So, this update is just for compatibility, right? It no longer shows undefined, but now the default selection is gpt-3.5-turbo. I don’t have access to gpt-3.5-turbo, it’s become unusable for me.

As a result, I tried using CUSTOM_MODELS. It works, but by default, it shows that I haven’t selected any model.

CUSTOM_MODELS=+gpt-3.5@openai

Yes. default model still doesn't work properly, though no () will be displayed.

1. yes, fixed undefined bug.
2. if you config defaultModel not in model list, this config will be ignore.
3. why select gpt-3.5-turbo: the chat component will select model which defined in mask, if model not in available model list, just select the first one.

As a result, I tried using CUSTOM_MODELS. It works, but by default, it shows that I haven’t selected any model.

1. gpt-3.5 is not a valid model name. so do not using this config.

if you config defaultModel not in model list, this config will be ignore.

2. if you want to show custom model name, please see 如何使用v2.13.0的自定义模型功能（how to use 2.13.0 multi models) #5001 or README.md.
