Attribution and license scope

Orukeet is an adaptation of NVIDIA Parakeet TDT 0.6B v3. NVIDIA retains copyright in its model and upstream work. The base weights are distributed under CC BY 4.0. Oruk AI's changes comprise multilingual/accent continuation training, parameter blending, fitted and frozen Gabor-kernel replacement and recovery, native and ONNX export, application integration and evaluation. Model stages identifies r3 as the source of every current Orukeet download and records its ancestry.

The r3 NeMo, ONNX INT8, Q8 GGUF and F16 GGUF weights, and their fitted Gabor kernels, are designated CC BY-SA 4.0. The complete license is in LICENSE-WEIGHTS. This permits commercial use and modification, with attribution and applicable ShareAlike requirements. Earlier checkpoints retain their source notices and are not silently relicensed by this file. Orukeet v0.1.0 distributes the final r3 checkpoint in all four formats.

Python and integration code in this repository is MIT unless a file specifies otherwise. The native bindings, audio windowing and worker transport derive from OpenWhisper by Knuckles92 and its Oruk AI integration; their MIT notice is retained in LICENSE. The downloaded NVIDIA NeMo-Speech.cpp SDK and its bundled dependencies retain their own notices, including Apache-2.0 and MIT components. Keep the SDK's license files when redistributing it. The pinned source is the authority for those terms.

The ONNX exporter follows sherpa-onnx's Parakeet TDT v3 conversion script. Its upstream reference and Apache-2.0 license are retained in export/onnx. The ONNX archive includes the weight license and source attribution. The optimized ONNX encoder uses exactly equivalent FP32 arithmetic for 24 quantized depthwise convolutions, with existing runtime operators and unchanged quantized values. Original export and separate optimization receipts are retained in the GitHub repository under evidence/onnx-r3-20260910/ and evidence/speed20260910/.

Data were filtered, split, normalized and sampled as described in data and licenses. Corpus copyrights and source terms remain with their owners. Evaluation-only data have separate terms. No endorsement by NVIDIA, Mozilla, Google or the other source projects is implied.

The generated statistical records in evidence/metric-evidence.tar.gz, the Gabor recovery count bundles under training/gabor_half/results/, and the FT-4035 benchmark counts under evidence/regression-ft-20260907/ are designated CC BY 4.0, attributed to Oruk AI. This designation covers the prepared metric records; it does not relicense the original corpus recordings or transcripts, which are not included in that archive.

The r3 numeric benchmark records in evidence/standard-asr-r3-20260908/ and evidence/domains-r3-20260908/ are released under CC BY 4.0. They contain error counts and recording identifiers; dataset audio remains with its providers.

The paired ONNX application benchmark counts in evidence/onnx-r3-20260910/ are also released under CC BY 4.0. These records contain numeric errors, timings and recording identifiers, without corpus audio or transcripts.
