Qwen3-ASR Service

Qwen3-ASR-1.7B on RunPod serverless GPUs: multilingual speech recognition with context biasing, language identification, and word-level timestamps.

The problem

Speech recognition is bursty work. Keeping a GPU warm around the clock for it wastes most of what you pay for.

What I built

  • Qwen3-ASR-1.7B packaged as a RunPod serverless worker, so a GPU is only billed while a request is running.
  • Context biasing, language identification, and word-level timestamps exposed through the API.
  • Published on the RunPod Hub so it can be deployed by anyone in a couple of clicks.

What it moved

  • Listed on the RunPod Hub with the source public on GitHub.
