Runway Gen-3 Alpha Turbo was retired on July 30, 2026, and is no longer available. For current work, the right replacement depends on the task: Runway points creators to Gen-4.5 for text-to-video or image-to-video, Animate Frames for keyframes, and Edit Studio Aleph 2.0 for video-to-video. API users have a separate migration recommendation: Gen-4 Turbo when speed is the priority, or Gen-4.5 when quality is the priority.
What happened to Gen-3 Alpha Turbo?
Runway’s Help Center says Gen-3 Alpha Turbo was retired on July 30, 2026, and that the feature is no longer available. Runway Dev’s API changelog confirms that API requests using the gen3a_turbo model identifier fail after the retirement.
Gen-3 Alpha Turbo was a historical video-generation model. Its old specifications and credit rate should not be treated as a currently usable service or purchase option.
What Gen-3 Alpha Turbo offered
Runway’s API billing documentation lists the retired Turbo model at 5 credits per second, with 5- or 10-second clips and 720p output in landscape or portrait. These are historical API specifications, not a guarantee of web-app terms or a current way to generate videos.

- AI Performance: 767 AI TOPS
- OC mode: 2632 MHz (OC mode)/ 2602 MHz (Default mode)
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure
- A 2.5-slot design maximizes compatibility and cooling efficiency for superior performance in small chassis

Runway’s current documentation does not make those historical figures a like-for-like comparison with successor tools. Specifications and billing can change.
What should I use instead of Gen-3 Alpha Turbo?
Choose based on what you are trying to do. Runway’s Help Center maps the retired web feature to different current tools, while its API changelog gives API users a speed-versus-quality migration choice.

| Task | Runway’s current direction | Important distinction |
|---|---|---|
| Generate from text or an image | Gen-4.5 | Runway lists text-to-video and image-to-video. |
| Migrate an API workflow prioritizing speed | Gen-4 Turbo | Runway identifies it as the fastest upgrade; it is not necessarily behaviorally identical to Gen-3 Alpha Turbo. |
| Migrate an API workflow prioritizing quality | Gen-4.5 | Runway identifies it as the best-quality upgrade. |
| Work with keyframes | Animate Frames | Runway’s retirement notice gives this as the current keyframe replacement. |
| Edit video with video-to-video functionality | Edit Studio Aleph 2.0 | Runway’s retirement notice lists this task mapping. |
These speed and quality descriptions are Runway’s guidance, not independently benchmarked comparisons. Runway describes Gen-4.5 as its most advanced video model and Gen-4 and Gen-4 Turbo as older, faster and lower-credit models; those are also Runway’s product characterizations.

How to plan a migration
- Identify whether your workflow is generation, keyframe work, video-to-video editing, or an API integration.
- For a web workflow, use Runway’s task mapping: Gen-4.5 for generation, Animate Frames for keyframes, or Edit Studio Aleph 2.0 for video-to-video.
- For an API workflow, choose Gen-4 Turbo if Runway’s speed priority fits your needs, or Gen-4.5 if its quality priority fits better.
- Review the current model documentation, inputs, output limits, availability, and billing before changing a workflow.
- Test the chosen replacement with your own prompts and assets; do not assume that it matches the retired model’s behavior.
For API users, the retirement has a direct operational consequence: requests using gen3a_turbo fail. Update integrations to a currently supported model rather than continuing to send requests to the retired identifier.

Is Runway Gen-3 Alpha Turbo still available?
No. Runway says it was retired on July 30, 2026, and is no longer available. API requests using the gen3a_turbo identifier fail after retirement.
