Currently the UI only supports English language. It would be good if we can support other languages as well such as spanish, chinese.

From POC feedback session held on 1/23/25 in Boston:

Interest in models that support more languages:

• looking for IBM granite support of natural languages
• Native languages, support other models beside Granite when you need another language
• Or add more languages to Granite, which heard is hard
• How do I bring in 1000 documents in Swedish?
• How to create a qna in my language

From UXD interview with SMEs on 1/27/2025:

• We need to consider global workforce where they doesn't speak English as their first language and the need to keep our wording simple and be mindful around the use of technical terminologies.
