Whisper Tiny

Bash, curl, jq and Python 3; an existing workspace API key, an operator-issued noncash development grant and a supported private WAV are required. Set MODELUSE_TOKEN and MODELUSE_WAV locally. Never put them in a public URL or log.

This example uses the same recipe, task reference and service as the form. It saves only private run state and the result on your own machine. Reuse its directory and key to recover the same request; do not repeat an uncertain upload.

To cancel accepted work, use its saved job ID with POST /v1/jobs/{job_id}/cancel and the same existing credential. Leaving this page or stopping the script does not cancel a job.
