OpenArt vs Elyumfor MiniMax H3
OpenArt puts MiniMax H3 Max on a $175 Wonder unlimited lane; Elyum charges only the takes you keep, after a free preview.
MiniMax H3 is MiniMax's video model for 5 to 15 second clips from text, a still, or reference images and audio. Practitioners use it for the H3 look at a length you can actually ship: a product hero, a short walk, a room that holds still then breathes. You can run it as text to video, image to video, or reference to video. On Elyum the same model goes from 480p through 4K; a 5s 4K keep is 90 credits ($0.90). Knobs sit on the MiniMax H3 page.
The model is the same vendor weights. The platforms are not. OpenArt's pricing page lists Wonder at $175/mo with 106,000 credits and Unlimited Creation that applies only to MiniMax H3 Max. It does not list a MiniMax H3 credit price per second or per clip. Elyum bills per second and only when you keep; see the pricing page. Trustpilot reviewers report failed or bad generations still consuming OpenArt credits, with no published automatic refund. On Elyum a failed generation is never charged, and a kill refunds in full (one kill a month on Free; paid plans kill freely).
OpenArt is stronger on suite. Director, One-Click Story, and consistent-character slots (13 on Starter, 353 on Wonder) are reasons to generate MiniMax H3 Max there if the job is a multi-shot narrative. Elyum does not have a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed. Isolated 4K keeps with cheap misses belong on Elyum. Storyboard work that needs Director belongs on OpenArt. Details sit on the OpenArt alternative page.
MiniMax H3 on OpenArt
OpenArt offers MiniMax H3 Max behind Wonder's Unlimited Creation. Wonder is $175/mo: 106,000 credits, 353 consistent characters, priority support, commercial use. OpenArt does not publish a MiniMax H3 per-clip or per-second credit cost. Starter is $13/mo (4,000 credits, 13 characters, 8 parallel generations, watermark-free, no commercial rights). Plus is $27/mo (12,000 credits, commercial use, 40 characters, 16 parallel). Pro is $44/mo (24,000 credits, 80 characters, 32 parallel). The official pricing page fetched on 2026-09-07 did not show a free-tier line; checkthat.ai says the free tier has no video generation access.
A bad MiniMax H3 take on OpenArt has no official automatic refund. Trustpilot reviews and a 2026 review write-up name credits burned on failed or low-quality renders as a frequent complaint. Billing complaints also include charges after people believed they had canceled. Extra credits are a $15/mo add-on of 5,000, sold as requiring Plus or higher; checkthat.ai says add-on credits persist while base credits expire monthly, which openart.ai did not independently confirm. OpenArt has an MCP server; no separate public API price was on the official pricing page.

| Ten takes, keep two | Not published; ten H3 clips have no official credit math | 2 × 25 credits = 50 credits ($0.50) (two 5s 480p keeps; eight kills refund) |
| A failed generation | Reviews report credits still consumed; no automatic refund found | Never charged; kill refunds a preview you reject |

Where the two differ
OpenArt sells MiniMax H3 Max as Unlimited Creation on Wonder ($175/mo, 106,000 credits). It does not publish a per-second H3 rate. Elyum bills per second only on keep: 5 credits/s at 480p, 18 at 4K.
OpenArt has no published automatic refund. Trustpilot threads repeatedly say failed renders still burn credits. On Elyum the preview is free, a kill refunds in full, and a failed job is never charged. Free Elyum meters kills at one a month.
Elyum publishes 480p, 768p, 2K, and 4K, with clips from 5 to 15 seconds. OpenArt's max clip length and MiniMax H3 resolution were not confirmed in the 2026-09-07 research. Do not assume 4K is available on OpenArt.
OpenArt has Director, One-Click Story, and consistent-character slots from 13 on Starter to 353 on Wonder. Elyum has no timeline editor, no stock footage, no avatars, no team seats, and no community feed. Single-clip studio only.
Both offer MCP for agents. Elyum documents that path on the MCP docs and a REST API on the API docs. OpenArt listed no separate public developer API pricing on its official pricing page.
OpenArt grants commercial use on Plus ($27), Pro ($44), and Wonder ($175). Starter and the free tier exclude it. Elyum includes commercial use on kept takes, including Free, with no watermark.
Pick OpenArt when
- You already pay $175/mo for Wonder and want Unlimited Creation on MiniMax H3 Max, not per-clip math.
- You need Director, One-Click Story, or consistent-character slots from 13 (Starter) to 353 (Wonder).
- You want 100+ image, video, and audio models on one OpenArt credit balance, including ElevenLabs.
- You want watermark-free output on the $13 Starter plan and do not need commercial rights.
Pick Elyum when
- You iterate: free preview, pay only on keep, full refund on kill. A failed job is never charged.
- You need published 4K and 5 to 15s rates, such as 90 credits ($0.90) for a 5s 4K keep.
- You want Free (up to 150 credits once (our algorithm may grant them)) or Plus at $9/mo, not a $175 Wonder lane for unlimited H3 Max.
- You will also jump to other Elyum models after a keep, in one credit balance.
MiniMax H3 in three styles, rendered on Elyum
Getting the most out of MiniMax H3
- Lock one camera verb per take (dolly in, pan left, crane up, handheld follow). Two camera moves in one prompt fight the motion field and MiniMax H3 will smear the subject.
- On image-to-video, name only the motion. The still already has face, wardrobe, and set; repeating them is how identity drifts across the 5 to 15 seconds.
- Reference-to-video wants one hero still plus a short action line. A second reference that disagrees on hair, age, or costume splits the face.
- Fit action to duration. Five seconds is one beat (pour, turn, sit). Fifteen seconds can take a walk and a look-back. Do not plot a scene change.
- Specify a surface and a light: wet asphalt, tungsten practical, hair rim. H3 holds material when you give it a texture, not a mood word.
- Do not stack quality adjectives or a negative that cancels the positive (no camera move vs slow push). Pick one motion intensity and keep the frame count honest.
