AgentCore Web Answer vs Web Search: who runs the model, what you get back, and what the managed tool decides for you
AWS announced general availability of Web Answer on Amazon Bedrock AgentCore on 5 November 2026. Web Search hands your agent ranked links and snippets and leaves synthesis to your own model. Web Answer runs the retrieval loop, model, synthesis and citation step and returns a finished cited answer through AgentCore Gateway. This piece compares the returned artifact, the permissions, the controls you keep, the $10 per 1,000 tool calls price and the limits, including what AWS's guide does not establish.

Bedrock's AgenticRetrieveStream now takes maxAgentIteration 0 or 1: passages only, or one retrieval plus one answer
On November 9, 2026, AWS said Amazon Bedrock Managed Knowledge Base can run retrieval-only and single-shot RAG requests through AgenticRetrieveStream. Setting maxAgentIteration to 0 with generateResponse false returns passages with no foundation model call. Setting it to 1 retrieves once and generates one answer with no planning rounds. Values 2 to 5 keep the existing agentic behavior. The application chooses the mode; the parameter does not route requests automatically. AWS gives no new latency, cost or accuracy measurements, and the passages-only stream differs in shape from a direct Retrieve call.

Google's MKA benchmark tests AI agents on 200 private professional tasks; a separate set of 10 public tasks is available for inspection
Google DeepMind's new Multimodal Knowledge Agent benchmark evaluates AI agents on 200 private tasks requiring visual analysis of complex professional files like architectural blueprints and engineering schematics. While the benchmark's headline scores are based on these private evaluations, only 10 sample tasks are publicly available for inspection. The benchmark uses weighted criteria where harder 'Climb' criteria measure advanced performance, and costs reported by Artificial Analysis exclude judge calls, limiting direct workplace cost comparisons.
