What changed
Cohere opened a managed private beta of Compass, its enterprise retrieval stack, through APIs, a separately versioned MCP server and a Python SDK. It combines parsing, dense and sparse embeddings, hybrid retrieval, reranking, document permissions and retention policies; self-hosted deployments remain available.
Why it matters
Retrieval becomes a managed agent dependency rather than an internal pipeline. Permission enforcement, deletion and tenant isolation now need to survive repeated machine-generated queries, not only a single search request.
What to do
Request access only with a representative permission hierarchy. Test deleted-content resync, tenant isolation, multi-hop queries and citation traceability, and compare relevance and latency against the current stack using an independently labelled set.
Caveat
Access is limited private beta. Cohere's reported 14–16 point benchmark gain uses an internal annotated finance set and is not independent evidence or a general production result.
