How Much Does Grok Imagine Cost? Per-Second Pricing on FlyAIgh (2026)

Grok Imagine (xAI's text-to-video model) is one of the budget picks of FlyAIgh's video lineup. But "cheap" only means something with a number attached, so this guide gives the exact cost: what a Grok clip runs in credits and in dollars, why resolution does not change the price here, and how far the $11.99 Basic membership actually stretches.

Every figure below is the real pricing pulled from the model registry, quoted at the Basic plan's rate of about $0.030 per credit. On any higher tier or on annual billing each credit is cheaper, so you pay less than what's shown here — never more.

The short answer

Grok Imagine costs 3 credits per second, flat across both of its resolutions (480p and 720p). At the default 6-second length that's 18 credits ≈ $0.54 per clip on the $11.99 plan; the 10-second option is 30 credits ≈ $0.90. It draws from the same shared credit wallet as every other model — no separate Grok subscription, no per-generation fee.

How Grok Imagine is billed: per second

Grok Imagine is billed strictly per second — there is no flat per-clip charge. The rate is 3 credits per second at either resolution, so your final cost is simply seconds × 3. Two things to know:

• Duration. Grok offers 6-second (default) and 10-second clips. Cost scales linearly — 18 credits for 6s, 30 credits for 10s.
• Resolution. Grok offers 480p and 720p — and they cost the same. There is no resolution multiplier, and no 1080p or 4K option on Grok.

That's the whole model — no audio surcharge, no resolution premium. The generate screen always shows the credit cost for your chosen duration before you spend anything.

Grok Imagine price table (6s and 10s)

Here is the entire menu — two durations, one flat rate across resolutions. Credits are exact; dollar figures use the Basic rate of $0.030 per credit (so they round slightly):

• 6s · 720p (default) = 18 credits ≈ $0.54
• 6s · 480p (same flat rate) = 18 credits ≈ $0.54
• 10s · 720p = 30 credits ≈ $0.90
• 10s · 480p = 30 credits ≈ $0.90

Those four rows really are the whole price list — 6 or 10 seconds, one rate. The full spec and a sample sit on the Grok Imagine model page.

What a credit actually costs

All the dollar figures above use the Basic rate, but the per-credit price falls as you move up tiers. The full ladder — monthly price, credits, and resulting per-credit cost:

• Basic — $11.99/mo, 400 credits → ~$0.030 per credit (annual: $9.59/mo-equiv → ~$0.024)
• Basic Plus — $19.99/mo, 720 credits → ~$0.0278 per credit (annual: $15.99 → ~$0.0222)
• Basic Max — $31.99/mo, 1,200 credits → ~$0.0267 per credit (annual: $25.59 → ~$0.0213)
• Pro — $47.99/mo, 2,000 credits → ~$0.0240 per credit (annual: $38.39 → ~$0.0192)
• ULTRA — $79.99/mo, 3,600 credits → ~$0.0222 per credit (annual: $63.99 → ~$0.0178)

A Grok clip costs the same number of credits on every tier — 18 credits for a 6-second clip whether you're on Basic or ULTRA. What changes is the dollar value of those credits. On ULTRA annual (~$0.0178/credit) that same 6-second clip works out to about $0.32 instead of $0.54. See the live ladder on the pricing page.

How many Grok clips for $11.99?

400 credits, divided by the per-clip cost (whole clips only):

• 6s (default) (18 cr) → 22 clips
• 10s (30 cr) → 13 clips

That's 22 draft-length clips for the price of the entry membership. And because it's one wallet, you don't have to spend all 400 credits on Grok: a realistic month might be a stack of Grok drafts plus a few higher-end hero shots from another model, all out of the same balance.

One $11.99 wallet, every model

The reason Grok is cheap to keep, not just cheap to run, is the single shared wallet. You buy credits once into one balance, then spend them on whichever model fits the shot. Open the generator, pick Grok Imagine, and that same wallet pays for it; the full lineup is on the models page.

• No model paywall. Grok Imagine runs on the $11.99 Basic plan exactly like it does on ULTRA — higher tiers only add credits at a cheaper rate, they don't unlock the model.
• No idle Grok subscription. Skip Grok for a month and you've lost nothing; the budget was never earmarked to it.
• No per-vendor floor. There is no standalone monthly fee just to keep Grok available — you pay only for the seconds you generate.

How to keep Grok costs down

1. Test at 6 seconds, extend only the keeper. A 6s clip (18 credits) costs 40% less than a 10s one (30 credits). Lock the look on the short length, then re-run at 10 seconds only when the edit actually needs it.
2. Don't drop resolution expecting savings. Unlike most models, Grok bills 480p and 720p identically — lowering resolution buys you nothing here. Generate at 720p.
3. Use Grok as a budget tier in a mixed workflow. At 18 credits a clip Grok is one of the cheapest video options here — reach for it on volume and rough cuts, and reserve pricier models for the handful of shots that ship in high quality. Our cheap AI video generator guide lays out the multi-model cost plays.
4. Move up a tier only when volume justifies it. If you reliably spend 400 credits a month, Basic Plus or Pro lowers your per-credit price; if you don't, Basic keeps the floor tiny.

The honest fine print

• Grok is per-second, in two lengths. 3 credits per second: the default 6-second clip is 18 credits, the 10-second option is 30. Those are the only two durations Grok offers here.
• Only two resolutions — same price. 720p (default) and 480p both bill at the flat 3 cr/s. There is no 1080p or 4K on Grok Imagine; if you need higher resolution, that's a different model.
• Per-credit price varies by tier. Every dollar figure here uses Basic monthly ($0.030/credit); annual and higher tiers are cheaper (down to ~$0.0178). We never quote a lower per-credit rate while saying "$11.99."
• The free tier has 0 credits — it's for browsing, not generating. To actually create with Grok, you start on Basic at $11.99.

That's the whole picture: Grok Imagine at a flat 3 credits a second, about $0.54 for a default 6-second clip on a $11.99 membership, sharing one wallet with every other model. Open the generator and the exact cost of your clip is shown before you commit a single credit.
