# gen3a_turbo

Calls to the model gen3a_turbo on Runwayml stopped working on July 30, 2026.

On July 30, 2026, the model gen3a_turbo was retired on Runway Dev. Requests using model gen3a_turbo fail since that date. Runwayml also discontinued gen4_aleph at the same time.

## What to use instead

Upgrade from Gen-3 Alpha Turbo to Gen-4.5 for best quality or Gen-4 Turbo for fastest processing. For Gen-4 Aleph, migrate to Aleph 2.0 ( aleph2 ).
