A browser-based workspace to experiment with prompts and adjust model parameters without writing code is correct. It best describes Amazon Bedrock Playground.

The A browser-based workspace to experiment with prompts and adjust model parameters without writing code gives product owners a no-code web interface to try prompts, tweak parameters such as temperature and max tokens, and compare outputs before integrating models into applications. The Playground is meant for quick experimentation and side by side comparisons rather than deployment or audit logging.

It captures and audits prompt activity across accounts using AWS CloudTrail is incorrect because AWS CloudTrail captures API calls and audit logs while the Playground is an interactive console feature for trying prompts.

A tool that creates serverless inference endpoints and manages runtime parameter caching is incorrect because provisioning endpoints and managing runtime caching are deployment concerns handled by inference services and APIs, not the Playground interface.

An automated capability that fine-tunes models and promotes deployments across several AWS Regions is incorrect because the Playground does not perform automated fine tuning or manage multi region rollouts.
