# NousResearch/hermes-agent · STT CUDA failure mid-transcription CPU fallback fix

## Open now

- Nothing open on GitHub.

These items address a bug where local speech-to-text using Whisper did not fall back to CPU when CUDA errors (such as a missing libcublas library) occurred during segment iteration rather than at startup. The work adds retry logic to handle this mid-transcription failure case.

## TL;DR

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-112167`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
