Go 1.27 includes an experimental interface that lets developers write code for CPU instructions that process multiple data values at once without choosing a fixed vector size or writing a separate implementation for each processor. The Go team says the simd package supports AVX variants on amd64, NEON on arm64 and WebAssembly SIMD; it emulates operations where hardware support is absent.

Developers can use the interface for compute-heavy work such as data processing, cryptography and AI. It requires the GOEXPERIMENT=simd build setting, and the first release lacks some operations, including a way to sum all values in a vector.
