 # Cortex-M Backend
 
 > [!NOTE]
-> WIP. This is a temporary/placeholder backend for Cortex-M CPUs. It is not intended to be used in production, but rather as a proof of concept. Things will change without notice.
+> Beta. This backend has been validated with a set of small models (e.g. MLPerf Tiny, MobileNetV2) and provides broad operator coverage through CMSIS-NN accelerated kernels with portable-ops fallback.

 # Arm Cortex-M Backend
 
 :::{note}
-This backend is a work-in-progress proof of concept. It is not intended for production use, and APIs may change without notice.
+This backend is in **beta**. It has been validated with a set of small models (e.g. MLPerf Tiny, MobileNetV2) and provides broad operator coverage through CMSIS-NN accelerated kernels with portable-ops fallback.
 :::
 
 The Arm® Cortex®-M backend accelerates quantized model execution on Arm Cortex-M CPUs using [CMSIS-NN](https://arm-software.github.io/CMSIS-NN/latest/) optimized kernels. Unlike delegate-based backends, it operates as an operator library: quantized subgraphs are replaced with CMSIS-NN accelerated kernels during the pass-lowering stage, while unsupported operators fall back to portable fp32 kernels.
