parakeet tdt 1.1b: transcribe.cpp GGUF GGUF conversions of nvidia/parakeet tdt 1.1b for use with transcribe.cpp. Ported from upstream commit 53276c6, pinned 2026 05 10. Validated against the NeMo reference at transcribe.cpp commit 42528dd on 2026 05 10. Offline English speech to text. A 1.1B parameter FastConformer XL encoder with a TDT/RNNT transducer decoder. Takes a 16 kHz mono WAV and produces a transcript with optional token level timestamps. Not a streaming model and does not translate.
