Overview
Transcribe English and Spanish audio on CPU using faster-whisper and a pinned multilingual small model. Return text, segment and word timestamps without a model API account.
This is a repackaged open source software product wherein additional charges apply for independent packaging, setup documentation and maintenance by Software Sushi. Ubuntu 24.04 x86_64, first-boot TLS and private access files are included. Software Sushi is independent of the upstream project and does not claim upstream or AWS endorsement.
Launch t3.medium with at least 24 GiB encrypted gp3 root storage, IMDSv2 and inbound application ports closed. Connect using Session Manager as ubuntu or SSH restricted to an administrative CIDR. Wait for cloud-init and run sudo -iu ubuntu bash /opt/sushi/docs/demo.sh. Reach the HTTPS service on port 8443 through a Session Manager port-forwarding session or an SSH tunnel. The bundled customer guide explains private access files and your first request.
No provider key is required for local audio transcription. EC2, EBS and data transfer charges are separate from software charges. Back up customer data before replacing an instance.
The included HTTPS API transcribes WAV, FLAC and MP3 files of up to 10 MiB and five minutes per request, one request at a time, sized for t3.medium. For longer recordings, the complete faster-whisper Python SDK is installed and transcribes WAV, FLAC or MP3 files directly by filename with the bundled model, offline. A 5 minute 31 second recording was transcribed this way on a fresh t3.medium instance. Follow https://docs.softwaresushi.com/whisper-cpu/getting-started/#local-batch . Diarization, translation, live streaming and voice generation are not included.
Version 0.1.10 bundles the customer launch guide and real-use walkthrough under /opt/sushi/docs. Known issues: the complete 17 October 2026 host scan reports 680 High and 104 Critical matches in the pinned kernel and one FFmpeg advisory match (CVE-2026-107696) in a network protocol that the shipped media build disables. The complete Python runtime scan reports zero High/Critical matches. Read https://docs.softwaresushi.com/whisper-cpu/operations/#maintenance for the exact scan times, limitations and maintenance guidance before deployment.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Transcribe English and Spanish audio on CPU using faster-whisper and a pinned multilingual small model. Return text, segment and word timestamps without a model API account.

Retained host scan: 680 High/104 Critical kernel matches and one FFmpeg High match (CVE-2026-107696); Python runtime: zero High/Critical. Compiled-component coverage remains unverified and the full Software Sushi security gate has not passed. See the maintenance guide before deployment.
