Grok Imagine is the video model from xAI, offered on Twin AI as Grok Imagine Video. It is a genuine top-tier model that stands out for realistic human portraits with strong identity preservation — the person you start with still looks like themselves once the clip is moving. It ranks #3 for image-to-video overall, which is unusual for a model at its price. On Twin AI it sits in one interface with 30+ other models so you can compare it directly against the flagships.

Identity preservation is where a lot of video models quietly fall apart: a face that morphs, ages, or slides into a stranger over a few seconds. Grok Imagine is built to hold the likeness steady, which makes it a strong fit for anything where the viewer needs to recognise a specific person.

Strengths

• Realistic people, identity kept. Grok Imagine is especially strong at lifelike human portraits and holding a subject's identity through motion — a common failure point for other models.
• Top-tier image-to-video. An Elo of 1327 places it #3 for image-to-video; text-to-video sits at a strong 1233.
• Exceptional value. It delivers this quality at a top-tier-but-affordable price, which is rare in this bracket.
• Works from a single portrait. Give it one good photo and it can put that person convincingly into motion.

Price and speed

Grok Imagine is priced around $4.20 per minute of generated video — striking for a model ranked among the best for image-to-video. On Twin AI you spend credits rather than paying a foreign bill, and you only pay for the result, so its already-low rate goes further. That combination of top-tier ranking and low price is exactly why it stands out on the model list.

How to use Grok Imagine on Twin AI

1. Open /create/video and select Grok Imagine.
2. Upload a portrait for image-to-video (where its identity preservation shines) or write a prompt.
3. Generate. From Russia it works with no VPN, and you can top up with an RF card or SBP.

For the strongest likeness, start from a clear, front-facing portrait and describe the motion rather than the face — let the source image carry the identity.
