Higgsfield AI vs Elyumfor Grok Imagine 1.5
Elyum previews every Grok Imagine 1.5 take free and charges only kept files; Higgsfield AI bills credits on render and does not publish a per-clip price.
Grok Imagine 1.5 is a stylized xAI video model. Clips run 1 to 15 seconds. It accepts text to video, image to video, and reference to video. It holds a look and a short beat. It does not hold a plot. An 8-second push-in with a locked grade is the job. A 30-second scene with blocking is not.
Price structure changes first. On Elyum every render is a free preview; credits move only when you keep a take, and a kill refunds in full (Free: one kill a month; paid plans kill freely). Higgsfield AI meters credits when the job runs. Higgsfield AI's official pricing page does not itemize a Grok Imagine per-clip cost. Subscription credits there expire at the end of each cycle. Higgsfield AI lists Grok Imagine as an image model and added a separate Grok Video 1.5 on Jun 2, 2026, so name parity with Elyum's video SKU is not independently confirmed.
Higgsfield AI is the better desk if you want Soul Cast, Cinema Studio, or the Supercomputer in the same tab as the model. Elyum does not have a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed. If those are the job, stay on Higgsfield AI. If you are weighing the whole studio, not only this SKU, read the Higgsfield alternative page.
Grok Imagine 1.5 on Higgsfield AI
Higgsfield AI offers Grok Imagine. It does not publish which plan unlocks that SKU, or what one clip costs. The Higgsfield AI changelog lists Grok Imagine as an image model and a separate Grok Video 1.5 added Jun 2, 2026. Exact version parity with xAI's Grok Imagine 1.5 name was not independently confirmed beyond Higgsfield AI's own listing. No standing free tier sat on the official pricing page as of 2026-09-07. Basic Monthly is $9/mo for 120 credits. Pro Monthly is $43/mo ($23/mo effective on the yearly checkout path) for 900 credits.
A Trustpilot reviewer stated Higgsfield AI refunds credits if there is any error. No formal written refund or failed-generation policy was found on the official site, so a bad Grok Imagine take may still cost the credits the job consumed. Subscription credits do not roll over. They expire at the end of each credit cycle. Watermark policy, commercial-use terms, and max resolution for this model were not published on the pages retrieved. Higgsfield AI's MCP and CLI exist, but unlimited-plan perks stay on higgsfield.ai only.
Grok Imagine 1.5 on Elyum
On Elyum, Grok Imagine 1.5 is a video model. Clips are 1 to 15 seconds. Text to video, image to video, and reference to video. Billing is per second at 6 credits per second. A 5s take you keep is {{price grok-imagine-1-5 per second 5}}. A 15s take you keep is {{price grok-imagine-1-5 per second 15}}. The pricing page lists Free (up to 150 credits once (our algorithm may grant them), no card), Plus $9/mo, Pro $29/mo, and Ultra $69/mo. 1 credit equals $0.01. Pro and Ultra include fair-use unlimited image generation on selected image models, not this video SKU.
Every render comes back as a free preview. You judge it. KEEP is the only moment credits are charged. KILL refunds the full amount, automatically. A failed generation is never charged. Kept takes download clean and full quality, no watermark, commercial use included. The same balance runs in the web studio, Elyum's MCP server, and the REST API.

Where the two differ
Elyum charges only on KEEP. Higgsfield AI meters when the job runs. Higgsfield AI does not publish a Grok Imagine per-clip price or a cents-per-credit rate.
On Elyum a kill is a full automatic refund (one kill a month on Free; paid plans kill freely). A failed job is never billed. Higgsfield AI has no formal written refund policy on the official site. One Trustpilot reviewer said errors refund credits. That is unverified.
Elyum ships Grok Imagine 1.5 as video, 1 to 15 seconds, with text, image, and reference to video. Higgsfield AI lists Grok Imagine as an image model and added Grok Video 1.5 on Jun 2, 2026. Version parity is not independently confirmed.
Elyum: Free up to 150 credits once (our algorithm may grant them), Plus $9/mo, Pro $29/mo, Ultra $69/mo, plus top-ups. Higgsfield AI: no standing free tier; Basic $9/mo (120 credits), Pro $43/mo (900 credits). Higgsfield AI subscription credits do not roll over.
Higgsfield AI adds Cinema Studio, Soul Cast/Soul ID, and a Supercomputer agent. Elyum is one studio and one credit balance across 50+ models, plus MCP and REST, but has no timeline editor, stock, avatars, mobile app, team seats, or community feed.
Both offer MCP. Higgsfield AI's pricing page notes unlimited models and free generations are accessible only via higgsfield.ai, not MCP, CLI, Canvas, or Supercomputer. Elyum MCP and REST use the same keep/kill credit balance as the web studio.
Pick Higgsfield AI when
- You already rely on Soul Cast, Cinema Studio, or the Supercomputer and want Grok Imagine in that same Higgsfield AI workspace.
- You want Higgsfield AI Pro's time-limited unlimited windows on other models (Kling 3.0, Nano Banana) in the same subscription as Grok Imagine.
- You care more about Higgsfield AI shipping new models multiple times a week than about a published Grok Imagine per-clip price.
- You want Higgsfield AI's Discord and in-product Cinema tools, which Elyum does not offer.
Pick Elyum when
- You iterate. Free previews, then KEEP or KILL. Ten 5s tries and two keeps bill {{price grok-imagine-1-5 per second 5 x2}}, not ten renders.
- You want a published per-second rate. Failed Grok Imagine 1.5 jobs are never charged.
- You need the same model from the web studio, Claude, ChatGPT, or Cursor on one credit balance.
- Kept files have no watermark and include commercial use. Higgsfield AI did not state those terms on the pricing page retrieved.
Grok Imagine 1.5 in three styles, rendered on Elyum
Getting the most out of Grok Imagine 1.5
- Name one camera move and stop. Slow dolly in, 35mm, tripod holds on Grok Imagine 1.5. Two moves in a 5s or 15s clip usually smear the subject.
- Lead with materials and light, not plot. Wet asphalt, anamorphic smear, sodium vapor sticks. A three-beat story in 8 seconds does not.
- For image to video, treat the still as frame zero. Describe only motion that can start from that frame. Do not change wardrobe, lens, or lighting already in the still.
- For reference to video, one subject and one wardrobe. Two people swapping places inside 8 seconds is where faces drift on this model.
- Match the action to the duration slider. A 5s clip is a head turn or a coat flare. Do not describe a walk across a plaza if the clip is 5 seconds.
- Avoid tiny readable type, logo lockups, and five-finger close-ups. Stylized video models chew digits and hands first, and Grok Imagine 1.5 is no exception.
