I’ll share some of the trial and error points when using Japanese with the Amazon Titan foundation model on Amazon Bedrock. (Information as of January 13, 2024)

Background: Wanting to Use Japanese with Amazon Titan on Amazon Bedrock

I’ve documented my trial and error points when using Japanese with the Amazon Titan foundation model on Amazon Bedrock as a work log. Here are three points to share.

Models Cannot Be Used Without Request Access

To use Amazon Titan as a model on Amazon Bedrock, you need to request access from the Model access page. While I understand that other models require request access, I was surprised that Amazon’s own model also requires request access in the same way. I wish Amazon Titan would be available by default.

Titan Text – Express Is Not Available in Tokyo Region

Titan Text – Express is not available in the ap-northeast-1 Tokyo region, so you need to use either us-east-1 US East (N. Virginia) or us-west-2 US West (Oregon).

Initially, I was confused because Titan Text – Express didn’t appear when I selected ap-northeast-1, but I was able to use it successfully after switching the region to us-west-2.

Japanese Characters Are Garbled When Using AWS Console

I was able to reproduce the following:

Something that appears to be Japanese was returned. The console doesn't support multiple languages and seems to garble the characters.

That’s all from the Gemba, where I tried using Japanese with Amazon Titan on Amazon Bedrock.
