5.2.41. Parakeet (STT engine)¶

Parakeet is one of the STT engines selectable via STT_PROVIDER_SOURCE. It is documented under the STT Provider aggregator rather than as a standalone service, because the user-facing role is "pick an STT engine" — not "pick Parakeet":

→ See services/stt-provider/README.md for the full user-facing description, source-variant table, and configuration reference.

1. Engine quick reference¶

Image: nvcr.io/nvidia/pytorch:26.06-py3 (GPU only — Parakeet-TDT model)
License: CC-BY-4.0 (NVIDIA)
Activation: STT_PROVIDER_SOURCE=parakeet-container-gpu (or parakeet-localhost — Parakeet-MLX on macOS / native Linux)
In-container port: 8000
Host port: ${STT_PROVIDER_PORT} (computed from BASE_PORT by the bootstrapper)
Readiness: Uvicorn starts while a deadline-bounded background task loads the configured model. GET /health returns 503 until loading completes.

This manifest also owns the broader STT_PROVIDER_SOURCE enum (every STT option across engines), which is why it lives here historically rather than on the aggregator. The manifest (service.yml) and compose fragment (compose.yml) in this folder are the bootstrapper's source of truth for those values; treat this README as a pointer, not a duplicate of the aggregator doc.
