The expensive way to generate AI video in 2026 is to open a subscription with every vendor: one plan for Grok Imagine, another for Hailuo, another for Seedance, another for Kling. Each one has its own monthly floor, its own login, its own billing — and you pay for all of them even in months you barely touch a given model.
The cheap way is one membership with one shared credit wallet. FlyAIgh's Basic plan starts at $11.99/month for 400 credits — about 3¢ per credit — and those credits spend on any of the four models above (plus images) with no per-vendor fee. This guide shows the exact per-clip credit and dollar costs so you can see precisely what your $11.99 buys.
The problem: a subscription per vendor
Each model family is genuinely good at different things — Grok Imagine is the budget workhorse, Hailuo follows direction tightly, Seedance does cinematic multi-scene work, Kling is strong on character and motion. A serious creator wants all four. But buying four separate subscriptions means four monthly floors and four pools of credits that don't talk to each other. Burn through your Kling allowance mid-month and your unused Grok budget can't help you.
One membership, one wallet, every model
On FlyAIgh you buy credits once into a single balance, then spend them wherever you like. Open the generator, pick the model that fits the shot, and the same wallet pays for it. The full lineup lives on the models page; the four this guide focuses on are Grok Imagine, Hailuo 2.3, Seedance 2.0 and Kling V3.
- No model paywall. Every model runs on the $11.99 Basic plan — higher tiers only add credits at a cheaper rate, they don't unlock models.
- No idle subscriptions. Skip a model for a month and you've lost nothing; the budget was never earmarked to it.
- One shared library. Everything you generate, across every model, lands in the same place.
What a credit actually costs
Credit prices fall as you move up tiers. Here is the exact ladder — monthly price, credits, and the 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)
Per-clip cost for all four models
Video is billed per second, and most of these models add a resolution multiplier — so an honest cost needs a duration and a resolution. Below, each model is shown at its default duration and default resolution (the cheapest sensible config), with the higher-resolution option where it matters. Dollar costs use the Basic rate of $0.030/credit.
Grok Imagine (per-second, 2 credits/s; default 6s):
- 6s · 720p (default) = 12 credits ≈ $0.36
- 6s · 480p (cheaper, 0.7× multiplier) = 8.4 credits ≈ $0.25
Hailuo 2.3 (per-video billing; default 6s, 768p):
- 6s · 768p (default) = 18 credits ≈ $0.54
- 10s · 768p = 30 credits ≈ $0.90
- 6s · 1080p (1.6× multiplier; 1080p is 6s-only) = 28.8 credits ≈ $0.86
- Hailuo 2.3 Fast · 6s · 768p = 11 credits ≈ $0.33 (the cheapest premium-quality clip here)
Seedance 2.0 Pro (per-second, 8 credits/s; default 5s) — the widest resolution spread, so quote carefully:
- 5s · 720p (default) = 40 credits ≈ $1.20
- 5s · 1080p (2.5× multiplier) = 100 credits ≈ $3.00
- 5s · 4K (5.1× multiplier) = 204 credits ≈ $6.11
- Seedance 2.0 Fast · 5s · 720p (720p-only, flat) = 35 credits ≈ $1.05
Kling V3 (per-second, 8 credits/s; default 5s):
- 5s · 720p (default) = 40 credits ≈ $1.20
- 5s · 1080p (1.6× multiplier) = 64 credits ≈ $1.92
- Kling V3 Omni · 5s · 720p = 40 credits ≈ $1.20 (same pricing as V3)
And the matching image model, since it shares the same wallet — Kling Image 3.0 (quality-tiered): 1K = 4 credits ≈ $0.12, 2K = 5 credits ≈ $0.15, 4K = 8 credits ≈ $0.24.
How many clips you get for $11.99
400 credits, divided by the per-clip cost above (whole clips only):
- Grok Imagine 6s/720p (12 cr) → 33 clips; at 480p (8.4 cr) → 47 clips
- Hailuo 2.3 6s/768p (18 cr) → 22 clips; 6s/1080p (28.8 cr) → 13 clips
- Hailuo 2.3 Fast 6s/768p (11 cr) → 36 clips
- Seedance 2.0 Pro 5s/720p (40 cr) → 10 clips; 5s/1080p (100 cr) → 4 clips; 5s/4K (204 cr) → 1 clip
- Seedance 2.0 Fast 5s/720p (35 cr) → 11 clips
- Kling V3 5s/720p (40 cr) → 10 clips; 5s/1080p (64 cr) → 6 clips
- Kling Image 3.0 2K (5 cr) → 80 images; 1K (4 cr) → 100 images; 4K (8 cr) → 50 images
Because it's one wallet, you don't have to pick one model — a realistic month might be a dozen Grok drafts, a few Seedance hero shots, and a stack of Kling images, all out of the same 400 credits.
How to stretch credits further
- Draft cheap, finish dear. Iterate at the cheapest config — Grok Imagine at 480p (8.4 cr) or Hailuo 2.3 Fast (11 cr) — until the shot is right, then re-run the keeper once at 1080p or on Seedance. You pay the expensive multiplier exactly once instead of on every failed attempt.
- Default to 720p. The jump to 1080p costs 1.6× on Kling/Hailuo and a steep 2.5× on Seedance; 4K is 5.1× on Seedance. Reserve the high-res multiplier for shots that genuinely ship in high res.
- Use Fast variants for volume. Hailuo 2.3 Fast (11 cr) and Seedance 2.0 Fast (35 cr, flat 720p) are the cheapest paths to a high clip count.
- Lock characters once, reuse everywhere. Build a reusable character so you're not burning credits re-rolling for a consistent face across shots — see our character consistency guide.
- 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.
Planning a whole sequence rather than one-off clips? The AI storyboard generator turns a script into connected shots and reuses the same cast across the board — which is the biggest credit saver of all, because you re-roll far less.
The honest fine print
- Every video model is per-second. The clip costs above use each model's default duration (Grok 6s, Hailuo 6s, Seedance 5s, Kling 5s). Longer clips cost proportionally more.
- Resolution multipliers are real. Seedance 2.0 Pro 720p → 1080p → 4K is 40 → 100 → 204 credits; Kling and Hailuo are 1.6× at 1080p; Grok's 480p is actually cheaper than its 720p default. Seedance 2.0 Fast is the exception — 720p-only, flat 7 credits/s.
- 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, you start on Basic at $11.99.
That's the whole pitch: instead of four subscriptions, one membership from $11.99/month, one wallet at roughly 3¢ a credit, and Grok Imagine, Hailuo, Seedance and Kling all on tap. Open the generator and the cost of each clip is shown before you commit a single credit.
FAQ
What's the cheapest way to use Grok Imagine, Hailuo, Seedance and Kling?
Put all four on one membership instead of paying a separate subscription to each vendor. On FlyAIgh's Basic plan ($11.99/month, 400 credits) every model shares a single credit wallet at about $0.030 per credit. At default settings that's roughly $0.36 for a 6-second Grok Imagine clip, $0.54 for a 6-second Hailuo 2.3 clip, $1.20 for a 5-second Seedance 2.0 Pro clip and $1.20 for a 5-second Kling V3 clip — no per-vendor fee, no minimum spend per model. Annual billing drops the per-credit price further (Basic annual works out to about $0.024 per credit).
Do I need a separate subscription for each model?
No. That is the whole point of one membership. With FlyAIgh you buy credits once into a single wallet, then spend them on whichever model fits the shot — Grok Imagine, Hailuo 2.3, Seedance 2.0 or Kling V3 — without opening or paying for four separate accounts. The same wallet also covers image models like Kling Image 3.0.
How much does FlyAIgh cost?
The entry membership is Basic at $11.99/month for 400 credits, which is about $0.030 per credit. Annual billing is cheaper at $9.59/month-equivalent (about $0.024 per credit). Higher tiers buy more credits at a lower per-credit rate — Basic Plus ($19.99/720), Basic Max ($31.99/1,200), Pro ($47.99/2,000) and ULTRA ($79.99/3,600) — bottoming out near $0.0178 per credit on ULTRA annual. Every model is available on every paid tier.
How many videos can I make on the $11.99 plan?
It depends which model and settings you pick, because video is billed per second and most models have a resolution multiplier. At default settings, 400 credits buys roughly 33 Grok Imagine clips (6s/720p), 22 Hailuo 2.3 clips (6s/768p), 10 Seedance 2.0 Pro clips (5s/720p) or 10 Kling V3 clips (5s/720p). Mixing cheaper options — Hailuo 2.3 Fast at 11 credits, or 80 Kling Image 3.0 images at 5 credits each — stretches the same 400 credits much further.
Is every model included on the cheapest plan?
Yes. There is no model paywall by tier — the Basic $11.99 plan can run Grok Imagine, Hailuo 2.3, Seedance 2.0 and Kling V3 exactly like the top tier does. Higher tiers only change how many credits you get and how cheap each credit is; they do not unlock extra models.
Why is one wallet cheaper than four subscriptions?
Separate vendor subscriptions each carry their own monthly floor, and you pay all of them whether or not you use that model in a given month. A single shared wallet has one floor ($11.99) and one per-credit price (~3¢), and any unused budget can go to whichever model you actually reach for. You stop paying for idle subscriptions to models you only use occasionally.
