Blizzard, our default model, is a powerful and expressive text-to-speech model that delivers natural, high-quality voice synthesis with excellent prosody and emotional range.
Note: The Aurora model ID (aurora) is now an alias that routes all requests to Blizzard.
As Blizzard has reached production maturity, we’ve consolidated our model offering to provide a single, high-performance solution.
This change ensures consistent quality and reliability across all voice synthesis requests.
Model Updates & Changes
Regular Updates
Models receive regular updates and improvements. Most updates are non-breaking and require no changes to your applications.
Breaking Changes
When we need to make breaking changes:

- Send deprecation notices through the API headers
Model Version Tracking
You can find which specific model version handled your request in the API response headers under X-Model-Version. We recommend logging this value for debugging.
