Short answer
Runway Gen-3 Alpha is no longer available through Runway’s own product. Runway says it retired Gen-3 Alpha on July 8, 2026, and Gen-3 Alpha Turbo on July 30, 2026. Runway’s Free plan includes a one-time allocation of 125 credits, but those credits do not restore access to retired models. (Runway Help Center; Free plan details)
For Runway’s official production API, Gen-3 is not a current option either: Runway says requests using the Gen-3 Alpha Turbo identifier gen3a_turbo will fail, and Gen-3 Alpha is absent from the API’s listed accepted model identifiers. This describes Runway’s own channels; it does not establish whether a third-party provider still offers either exact model.
Free plan credits aren’t access to Gen-3
Runway describes its Free plan as $0/month with 125 credits, granted once. It provides access to a limited selection of models, and the selection can change. Since Runway has retired Gen-3 Alpha and Alpha Turbo, those free credits do not provide a way to generate with either model through Runway. (Runway Free plan details; retirement notice)
A free credit balance is not the same as free access to a specific model. An old price, tutorial, or third-party listing does not by itself show that Gen-3 can still be selected on Runway.
What about a production API?
Runway’s official API documentation lists accepted model identifiers for its video-generation endpoint, including gen4.5, but not Gen-3 Alpha. Runway separately states that gen3a_turbo is no longer available on Runway Dev and that requests with that identifier will fail. (Runway API reference; API changelog)
Runway Dev API billing is separate from the web-app Free plan. Runway says API credits cost $0.01 per credit, with sales tax potentially applying. That is a general API credit price—not a current Gen-3 rate. Since Gen-3 is retired on Runway Dev, this price does not provide a usable Gen-3 production budget. (Runway API pricing)
Third-party API availability and cost are unverified. The supplied Segmind listing describes Gen-3 Alpha Turbo, not Alpha, and provides no price, free allowance, or API integration details. The supplied CometAPI page generically describes a “Runway Gen-3 API,” but its captured text does not establish current production access to the exact Alpha model or give pricing, billing units, or a free allowance. These pages do not confirm that a third-party route is currently usable—or that none exists. (Segmind Alpha Turbo listing; CometAPI Gen-3 Alpha page)
If you need a current Runway workflow, the company points users to Gen-4.5 for text-to-video and image-to-video, Animate Frames for keyframes, and Edit Studio Aleph 2.0 for video-to-video. These are replacement workflows, not Gen-3 access; budget for them using their own current model rates. (Runway retirement notice)
Alpha vs. Alpha Turbo: both retired on Runway
Runway gives separate retirement dates: Gen-3 Alpha on July 8, 2026; Gen-3 Alpha Turbo on July 30, 2026. Its API changelog specifically confirms Turbo’s removal from Runway Dev and names the identifier gen3a_turbo. (Runway Help Center; API changelog)
A Segmind page calls Alpha Turbo “reduced cost,” but does not give a price or establish free access. Because it concerns Turbo and supplies no current pricing or availability terms, that relative claim is not a usable budget figure for Gen-3 Alpha. (Segmind Alpha Turbo listing)
Budget takeaway: Don’t buy a Runway plan or Runway Dev credits expecting to unlock Gen-3. Runway’s own product and official API no longer offer the model. Whether a third party currently provides the exact Gen-3 Alpha model—and what it would cost or include—remains unverified.
