Why Jarvis instead of running Whisper yourself
Running Whisper directly requires Python, a working CUDA or CoreML pipeline, and command-line glue. Jarvis bundles the same model quality in a one-click Mac install.
Accuracy
Jarvis uses Whisper-derived models optimized for Apple Silicon. Same Word Error Rate as running Whisper-large directly, faster inference on M1–M4.
Speed
Sub-300ms time-to-first-word on M3 Pro. Raw Whisper inference is 2–3x slower because it processes the full audio at once instead of streaming.
Voice control
Whisper transcribes. Jarvis transcribes and executes. "open Slack and reply to the design channel" works in Jarvis, not in raw Whisper.
