Why do you say they are different models? I've been looking at this today and haven't seen anything explicitly state that.
This is an older link, but they listed two different sections here, commercial and open source models: https://modelstudio.console.alibabacloud.com/?tab=doc#/doc/?...
For the realtime multimodal, I'm not seeing the open source models tab: https://modelstudio.console.alibabacloud.com/?tab=doc#/doc/?...
