No stt model devices configured

Error message

No stt model devices configured

What it means

When loading a transformers-engine STT model, loadPipelineWithDeviceFallback iterates tinyModelDeviceLoadOrder (the user's preferred device plus fallbacks such as webgpu/metal/cpu) and tries each; failures are logged per device. If every device in the load order fails, or the order itself is empty, it throws 'No stt model devices configured'.

Solutions

1. Check the per-device warn/error logs emitted before this throw to see why each device failed.
2. Update GPU drivers / ensure WebGPU (browser-grade) or Metal support, or force device=cpu via the tiny-model device preference config.
3. Clear the transformers model cache and retry in case a corrupted download caused each device load to fail.
4. Update @huggingface/transformers and onnxruntime to compatible versions.

const devices = tinyModelDeviceLoadOrder(preference);
if (devices.length === 0) throw new Error("no valid stt devices; check tiny-model device config");

try { const { pipeline, device } = await loadPipelineWithDeviceFallback(...); } catch (err) { // inspect logged per-device errors; surface guidance to fix drivers or force CPU }

When it happens

Trigger: Loading a transformers Whisper-tier model when every candidate device (GPU and CPU) fails to create the ASR pipeline, or when tinyModelDeviceLoadOrder returns an empty list for the resolved device preference.

Common situations: GPU runtime unavailable (missing WebGPU/Metal drivers) combined with a broken CPU fallback, an exotic device preference in config that yields no valid devices, or transformers.js unable to load the ONNX backend on any device.
