Evidence claims:
- [upstream_claim] README: faster-whisper is a reimplementation of OpenAI's Whisper using CTranslate2; up to 4 times faster than openai/whisper for the same accuracy with less memory; benchmarks run on CUDA 12.4 with an RTX 3070 Ti 8GB. · locator: README, intro and benchmarks · source: https://github.com/SYSTRAN/faster-whisper
- [sourced_fact] GitHub metadata: MIT, not archived, last push 2026-10-16. · locator: repository metadata · source: https://github.com/SYSTRAN/faster-whisper
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
