Hi @xinyu_chen

This is very useful. The content is marked as "Confidential and Proprietary".

Is there a version of the presentation that can be shared with customers? My first impression is that there is no much sensible information. Do you think this can be shared with customer, or what pieces should be removed to be safe?

Thanks
