Universal Containers’ data science team is hosting a generative large language model (LLM) on Amazon Web Services (AWS). What should the team use to access externally-hosted models in the Salesforce Platform?

Model Builder, a component of the Einstein 1 Studio, is the designated tool for integrating externally-hosted AI models with the Salesforce Platform. It provides a unified interface to connect to and manage various large language models (LLMs), including those hosted on third-party services like Amazon Web Services (AWS SageMaker and Bedrock), Google Vertex AI, or custom models accessible via an OpenAPI specification. This "Bring Your Own Model" (BYOM) capability allows organizations to leverage their existing investments in external data science infrastructure while using the models securely within Salesforce for generative AI applications.

B. App Builder: This is a declarative tool used for creating and customizing user interfaces, such as Lightning pages and applications. It does not handle the integration of external AI models.
C. Copilot Builder: This tool is used to create custom AI assistants and actions. It consumes AI models that have already been connected and registered on the platform via Model Builder.

1. Salesforce Help Documentation, "Model Builder": "Model Builder lets you connect a large language model (LLM) that’s hosted outside of Salesforce... You can connect to models hosted on Amazon SageMaker, Amazon Bedrock, Google Vertex AI, or through an OpenAPI spec." (Salesforce Help, Einstein Generative AI, Model Builder section).

2. Salesforce Developers Blog, "Unlocking AI Potential with Einstein 1 Studio": "Model Builder: A tool that allows you to choose from a variety of LLMs from Salesforce’s trusted partners, or bring your own model (BYOM) and host it on the Salesforce Platform. This flexibility allows you to use the best model for your specific needs." (Einstein 1 Studio Overview).

3. Salesforce AI Documentation, "Einstein 1 Studio Guide": This guide details the components of Einstein 1 Studio, specifying that Model Builder is the foundational tool for making both Salesforce-provided and third-party models available to other tools like Prompt Builder and Copilot Builder.
