AWS gives Claude Opus 5 and Sonnet 5 in South Korea
AWS tells that the area where a model operates is more important than model strength.
Amazon Web Services (AWS) is the cloud unit of Amazon. It gives the Anthropic models Claude Opus 5 and Sonnet 5 in its Seoul Region, on Amazon Bedrock. The data stays in South Korea. AWS tells that no other cloud provider does this there. Luke Anderson is the head of data and AI for AWS in Asia-Pacific and Japan.
How it works
In-region is when the model and its data processing stay in one cloud region. Customer data does not go to servers in other countries. This helps banks, public bodies and hospitals that have limits on cross-border data transfer. Bedrock also holds GPT models and open-weight models from Meta and Mistral.
The numbers
Anderson tells that Shinhan Bank made a customer agent with open-weight models. Its cost fell to about one-eighteenth, and the precision of its customer sentiment test went up. In South Korea, 37% of companies know AI agents and 8% have fully used them.
What is not known
AWS gave no price for the in-region models. It gave no test results that compare the models. Anderson tells that many projects stop after the proof of concept if the plan or model selection is not correct.
Insight: AWS sells the area and the controls, not one model
Bedrock holds Claude, GPT, Meta and Mistral models, and the model is not all that AWS gives. On 30 October 2026, AWS also added OpenAI GPT-5.6 to its US government cloud, with data kept in the US. This looks like a competition to control the area where models operate, because models are easy to change. Rules that attach data to a country help AWS. Tell each model vendor where it uses your data.
