Parakeet Redux fits in 178 MB and runs at 113× real time on CPU

huggingface.co 5 min read Editor score 8/10

Parakeet Redux uses 1.58-bit weights and runs at 113× real time on eight x86 CPU cores; its 178 MB size comes with English WER within 0.3 points of the original and stronger results on some listed benchmarks. The results make it a concrete example of aggressive quantization for fast, compact speech recognition.

What

- Parakeet Redux is a 1.58-bit speech recognition model with ternary encoder weights and the original model's architecture and tokenizer.

How

- It uses 178 MB and runs at 113× real time on eight x86 CPU cores; its English WER is within 0.3 of the original.

Why it matters

- Its small footprint and CPU performance could make speech recognition more practical in memory- or accelerator-constrained deployments.
