# makeSamples(_:targetCount:sessionProvider:validator:) Generates synthetic data based on this dataset and returns a stream of new samples. ``` func makeSamples(_ prompt: Prompt, targetCount: Int, sessionProvider: (@Sendable () -> LanguageModelSession)? = nil, validator: (nonisolated(nonsending) @Sendable (ModelSample) async throws -> Bool)? = nil) -> some AsyncSequence, any Error> where Element == ModelSample, T : Generable, T : Decodable, T : Encodable, T : Sendable ``` ## Parameters `prompt` The prompt the generator sends to the language model session. `targetCount` The desired total number of samples, counting both the initial dataset and newly generated ones. `sessionProvider` A closure that creates a new language model session, or `nil` to use the default. `validator` A closure that decides whether a generated sample is valid, or `nil` to accept all samples. ## Return Value An async throwing stream of newly generated samples. ## Discussion For more control over generation, create a `SampleGenerator` directly. --- Copyright © 2026 Apple Inc.
