chatMode

The chatMode parameter determines the chat modes available to Amazon Q Business users:

• RETRIEVAL_MODE - If you choose this mode, Amazon Q generates responses solely from the data sources connected and indexed by the application. If an answer is not found in the data sources or there are no data sources available, Amazon Q will respond with a "No Answer Found" message, unless LLM knowledge has been enabled. In that case, Amazon Q will generate a response from the LLM knowledge

• CREATOR_MODE - By selecting this mode, you can choose to generate responses only from the LLM knowledge. You can also attach files and have Amazon Q generate a response based on the data in those files. If the attached files do not contain an answer for the query, Amazon Q will automatically fall back to generating a response from the LLM knowledge.

• PLUGIN_MODE - By selecting this mode, users can choose to use plugins in chat to get their responses.

If none of the modes are selected, Amazon Q will only respond using the information from the attached files.
