We evaluated a lot of TTS providers before making Fish Audio the default in InsForge’s model gateway. It came down to quality, speed, and reliability — and Fish Audio checked all three. Now we’re running it across 15,000+ developers and over 1B tokens/month, and it’s been rock solid. The thing that stands out most is the model quality — you can tell there’s real research depth behind it. And the team ships fast and stays close to partners, which matters a lot when we’re scaling.
