Replicate vs Elyumfor Grok Imagine 1.5
Elyum charges only kept Grok Imagine 1.5 takes, while Replicate bills each prediction and does not publish a per-second rate or a bad-take refund.
Grok Imagine 1.5 is a short, stylized video model from xAI. On Elyum it is tagged quick, up to 15 seconds, with text to video, image to video, and reference to video. It is built for one motion idea, not a multi-scene film. Clip length runs from 1 to 15 seconds across three aspect ratios, so the same prompt can land as a feed post, a story, or a widescreen cut. See the Grok Imagine 1.5 page for modes and length.
What changes is the bill, not the weights. Elyum prices a keep at 6 credits per second and only charges when you KEEP a take. Replicate lists the same xAI video line as Grok Imagine Video: image-to-video with synchronized audio, about 30 seconds of generation time, and 16:9, 9:16, or 1:1. Replicate does not publish a Grok Imagine per-second rate, and the research found no failed-generation refund. Replicate has no free tier and no subscription plans. Elyum starts on Free with up to 150 credits once (our algorithm may grant them), then Plus at $9/mo, Pro at $29/mo, and Ultra at $69/mo. More platform context is on the Replicate alternative page.
Replicate is the broader developer catalog, with 50,000+ models, a CLI, Python/JS/Go SDKs, and custom LoRA hosting. Elyum is one studio and one credit balance across 50+ models, plus MCP and REST. We do not ship a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed. If Grok Imagine Video is one call among thousands, Replicate still fits. If you iterate and kill bad motion, keep/kill is the difference. Plan math is on pricing.
Grok Imagine 1.5 on Replicate
No plan unlocks Grok Imagine Video on Replicate. There are no subscription tiers, and there is no free tier. You pay from the first prediction. The Grok Imagine Video page describes image-to-video with synchronized audio, about 30 seconds of generation time, and 16:9, 9:16, or 1:1. The version number 1.5 and the exact per-second price were not confirmed on the fetched page.
A bad render's cost is unpublished. Failed-generation policy is not documented in the research, so do not assume a refund. Replicate's pricing page covers GPU-second billing for public open models and per-output billing for partner models. Typical video output across the catalog is reported at $0.09 to $0.25 per second of video. That band is catalog-wide, not a confirmed Grok Imagine rate. Watermark status on paid files is also unpublished.

- A kill refunds in full. Failed generations are never charged.
- Free starts with up to 150 credits (our algorithm may grant them) and no card. Plus is $9/mo, Pro $29/mo, Ultra $69/mo.

Getting the most out of Grok Imagine 1.5
- Write one beat, not a plot. Grok Imagine 1.5 is a 1 to 15 second stylized clip. Scene changes and montage language usually collapse into mush.
- Lock aspect first. A story frame wants a taller subject and less side dressing than a widescreen cut of the same line.
- For image to video or reference to video, attach a still that already has the face, product, and lighting you want. The model follows that frame more reliably than a text-only costume note.
- Give it one camera move: slow dolly in, gentle pan, or a short orbit. Two moves in a 5-second clip fight each other.
- Say what stays still. If the camera pushes in, lock the background. If the subject walks, keep the horizon level and avoid extra crowd motion.
- Do not ask for readable tiny type, multi-shot cuts, or a full conversation. Short stylized motion holds. Fine print and dialogue-heavy blocking do not.
