What is a key advantage of using open source foundation models (FMs) in AWS Bedrock?

They offer transparency, customization, and community innovation

Explanation

Open source models provide access to the cod, allowing for customization.  There is also the benefit of innovation from a community of contributors.  Bedrock will still charge for hosting the model on AWS.  You can specify real-time inference but it is not set by default.  While the codebase may be available, this may not be the case for the datasets.
