Fully managed grounding service: multimodal parsing, embeddings, vector storage and retrieval for agents
Commercial
What it is
Our note
AWS prices managed grounding by stored raw data rather than tokens, and the managed parser, embeddings and reranker are free, so cost tracks corpus size instead of call volume. It also serves as a data plane for the major open-source agent frameworks, which makes it the default context service for teams already on Bedrock.
