Gen-4.5

model version · in 30 sources (2026)

Gen-4.5 is Runway's in-house video model, available only on Runway, which Higgsfield's blog rates as the most predictable at following a specified camera angle, body position or movement. Its Director Mode builds a 3 to 5 shot story from a script and one portrait reference with no training, though clips run 10 seconds and lack native audio. It costs 12 credits per second, about 120 credits for a 10-second clip.
