Runwayml gen4_aleph model retirement

Stopped workingSubscribe to RunwaymlShare

On July 30, 2026, the model gen4_aleph stopped working and is no longer available on Runway Dev. Calls using the model gen4_aleph fail after this date. This change affects all requests relying on that model identifier.


What to use instead of gen4_aleph

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

In Runwayml's words

Gen-3 Alpha Turbo ( gen3a_turbo ) and Gen-4 Aleph ( gen4_aleph ) are no longer available on Runway Dev. Requests that use these model identifiers will fail.
