## Supported models

Every model below is validated at WER 0 against NeMo and published as GGUF (f16, q8_0, q6_k, q5_k, q4_k) in the single collection repo [mudler/parakeet-cpp-gguf](https://huggingface.co/mudler/parakeet-cpp-gguf). Convert any of them yourself with `scripts/convert_parakeet_to_gguf.py`. The per-model parity matrix is in [docs/parity.md](docs/parity.md).

## Performance

parakeet.cpp is faster than NeMo's PyTorch runtime on every Parakeet model, on both CPU and GPU, and the transcripts come out byte-identical (WER 0 vs NeMo). Full methodology, all 10 models, quantization tradeoffs, and plots are in [`benchmarks/BENCHMARK.md`](benchmarks/BENCHMARK.md).
