[Feature Request] Can we have also image generation as a 3rd model?

**Describe the solution you'd like**
Besides the 2 claude models, would be a 3rd one for image creation.

**Why the solution needed**
It would further show how our solution is more complete than competitor

**Additional context**
Add any other context or screenshots about the feature request here.

No files, tests, or entry points are identified. Start by locating the existing Claude model configuration and AWS Bedrock integration, then determine how an image-generation model would fit the chatbot flow. Done means a third image-generation option is available alongside the two Claude models and works end to end.
