Operator guidance
Gen-3 Alpha is the prior-generation Runway model. In most cases, Gen-4 Turbo offers better quality at a lower credit cost (5 vs 10 credits/second). Choose Gen-3 Alpha only if existing integrations require the gen_3a API endpoint, or for historical price comparison. Note: Gen-3 Alpha Turbo (gen_3a_turbo) is being sunset July 30 2026.
Use cases
- Cost comparison baseline against Gen-4 series
- Workflows that cannot upgrade from Gen-3 due to integration constraints
Limitations
- Prior-generation model; Gen-4 series offers better quality at lower cost
- No native audio generation
- Pricing confidence: estimated from plan math (no standalone credit purchase price)
- Gen-3 Alpha Turbo variant being deprecated July 2026
