# topK(_:axis:findLargest:) Adds a top-k operation to the current graph. ``` func topK(_ k: Int, axis: Int, findLargest: Bool) -> (values: BNNSGraph.Builder.Tensor, indices: BNNSGraph.Builder.Tensor) ``` ## Discussion The output of this graph is a pair of tensors `(values, indices)` that contains the top-k values and indices from the tensor from the given dimension. If `largest` is `true`, then output the largest `k` values and their corresponding indices, otherwise output the smallest. --- Copyright © 2026 Apple Inc.
