Summary

Fish Audio S2 is a new open-weight audio model available on Hugging Face, offering two models for timing and acoustic details, with fast inference and a hosted version S2.1 Pro supporting 83 languages at lower cost than ElevenLabs.

Here is a new open-weight audio model you can integrate with your app. I'm a huge sucker for open models that you can host to keep your data secure and away from Big AI. The model is Fish Audio S2. You'll find the weights, the code to fine-tune it, and a streaming inference engine in Hugging Face. (Link below). Under the hood, it's two models: a 4B one to handle timing and meaning, and a 400M one to fill in the acoustic details. The model is really fast! If you host it on an H200, it will start returning audio in about 100ms. If you don't want to host it, Fish Audio offers a hosted version: the S2.1 Pro. This model is even faster, with around 90ms latency, and it supports 83 languages. The S2.1 Pro is also ~83% more affordable than ElevenLabs: you pay around $15 for around 12 hours of transcribed audio, which is incredible. HuggingFace links below.
