When to stay with Fish Audio
Documented strengths from our Fish Audio review — switching isn't always the right call:
- Free s2.1-pro-free API model and an 8,000-credit monthly free tier make it cheap to start
- Pay-as-you-go API at $15 per million UTF-8 bytes (~12 hours of speech) with no monthly minimum
- Instant cloning needs only about 10 seconds of audio, a lower bar than many competitors
