Developers can configure the tool with a single line of code, customize it via guidance profiles to scope search capabilities for on-device models, add knowledge providers for reference resolution (e.g., contact resolvers), and implement custom pipeline stages for complex aggregation queries. The session also covers how to surface search results in the UI via async reply batches with query tokens, and how to evaluate model response quality and result coverage using the Evaluations framework with sample generation APIs. Available on iOS, iPadOS, macOS, and visionOS. ## Full article daily.dev links to this article rather than hosting it.
