Gov Cloud and Bedrock Foundational Model Selection

Hi,

We're about to kick off a project with a client operating exclusively in GovCloud, and they require the use of large language models (LLMs) with extended context windows (over 100K). Currently, the Bedrock services in GovCloud support only a limited number of models, and the available context windows are quite small (up to 8K).

Could you provide any updates or timelines for when additional LLMs with larger context windows might be made available in GovCloud Bedrock?

Thank you for your assistance!
