Amazon SageMaker Unified Studio provides a collaborative, secure, and centralized environment for end-to-end data, machine learning, and generative AI development. AWS documentation describes Unified Studio as a single interface where teams can prepare data, build models, train and deploy machine learning solutions, and develop generative AI applications .

In this use case, multiple teams must collaborate in a shared environment. SageMaker Unified Studio supports role-based access control, shared workspaces, and secure resource management , allowing developers to safely collaborate without compromising data or models. AWS highlights that Unified Studio integrates notebooks, pipelines, model development tools, and generative AI workflows into a consistent experience.

The service also supports model sharing, versioning, and reuse , enabling teams to build upon each other’s work. This directly satisfies the requirement to build and share both traditional ML models and generative AI applications securely.

The other options are not suitable. Amazon Lex is a conversational AI service, not a development environment. Amazon Bedrock PartyRock is a no-code generative AI playground and is not intended for enterprise collaboration. Amazon Q Developer focuses on developer productivity and code assistance, not unified AI development environments.

AWS positions SageMaker Unified Studio as the foundation for collaborative AI development at scale , making it the correct choice.
