GovCloud Model ID update

[sophyue]

Is your feature request related to a problem? Please describe.
When I was deploying the Govcloud deployment, I ran into issues with the Model ID not being accurate. In addition in order to update the model ID I had to create my own config file and then upload that to S3 and make a change set to Cloudformation

Describe the solution you'd like
I would like it if you created an option to choose from all the models that are available on Govcloud :All Titan Models, Claude Sonnet 4.5, Claude 3.7 Sonnet, Claude 3.5 Sonnet v1, Claude 3 Haiku,Llama 3 8B, Llama 3 70B

Describe alternatives you've considered
Customizing the config file worked, but it is a hassle

Can you enumerate exactly the modelIds for GovCloud.. Please limit these to Claude and Nova models already supported in commercial regions. (Llama is not supported since they are text-only)

us-gov.anthropic.claude-sonnet-4-5-20250929-v1:0

Can you refer me to where you sourced this list?
I'm curious about the us-gov prefix for anthropic, but not for the nova models

Also - where do i find pricing for these models in GovCloud region, so I can add to the pricing config? https://aws.amazon.com/bedrock/pricing/ doesn't seem to list GovCloud pricing.

Questions answered in slack..

Here is the approach i settled on..

• GovCloud Configuration Library for Pattern-1 and Pattern-2 - GitHub Issue #162
  • Added lending-package-sample-govcloud configurations for both Pattern-1 and Pattern-2 with GovCloud-compatible model IDs
  • Model ID Mappings for GovCloud:
    • us.amazon.nova-pro-v1:0 → amazon.nova-pro-v1:0
    • us.amazon.nova-lite-v1:0 → amazon.nova-lite-v1:0
    • All other models (Claude, Nova Premier) → anthropic.claude-3-7-sonnet-20250219-v1:0
  • Enhanced generate_govcloud_template.py to automatically set GovCloud configurations as default when generating GovCloud templates
  • Automatic Integration: GovCloud templates now default to lending-package-sample-govcloud configuration ensuring proper model IDs without manual configuration
