Model Detail

s2-pro is an audio model with 2.3B parameters released by fishaudio. The model is registered under the text-to-speech pipeline tag on Hugging Face, distributed under a other license.

s2-pro ships with 2.3B parameters. Total weight footprint is approximately 4.6 GB, which is the relevant figure when planning local-inference VRAM. Distribution is governed by the other license — review the exact terms before commercial deployment.

Downloads of s2-pro have moved +5.3% over the past 24 hours, +12.1% over the trailing seven days, -72.6% over the trailing thirty days. The trend is mildly positive, consistent with a model that is being picked up incrementally rather than going viral. These numbers are signal, not guarantee — week-over-week download counts on Hugging Face also reflect mirror traffic, CI scrapes, and one-off benchmarking runs.

s2-pro is best fit for speech recognition, transcription, or speech synthesis depending on the task head. Treat this as a starting matrix rather than a benchmark verdict — the right deployment usually depends on the specific evaluation suite that mirrors your workload.
