HiAPI Veo 3.1 API Pricing: How Much Does It Cost?

Veo 3.1 on HiAPI bills by the second of rendered video, not by a monthly plan. As of October 2026, the live rate for Veo 3.1 Standard is $0.57/s at 720p/1080p with audio ($0.86/s at 4K), Fast runs $0.25/s at 720p/1080p with audio ($0.60/s at 4K), and Lite runs $0.06-$0.14/s depending on resolution and whether audio is included (no 4K tier). There's no seat fee, no minimum spend, and you're billed only when a task finishes successfully. This guide covers exactly how that billing works, what each tier costs, how it stacks up structurally against calling Veo 3.1 directly, and how to keep costs predictable once you're generating at volume.

How HiAPI Bills Veo 3.1

Veo 3.1 runs through HiAPI's standard async task flow: you submit a generation request, poll (or get a callback) until it resolves, and you're billed only on a successful render — a task that errors out isn't charged. Price depends on three things: which of the three tiers you call, the output resolution, and whether audio is included.

Veo 3.1 Standard

Veo 3.1 Fast

Veo 3.1 Lite

Lite doesn't have a 4K tier. Image-to-video calls on all three tiers are priced the same as their text-to-video counterparts.

A few examples at these rates: an 8-second 1080p clip with audio costs $4.56 on Standard, $2.00 on Fast, or $1.12 on Lite. Drop audio on that same clip and Standard falls to $2.32, Fast to $1.36, Lite to $0.80.

These are live figures as of October 2026 — re-check current pricing before running a large batch, since per-second rates do change.

Veo 3.1 via HiAPI vs. Calling Veo 3.1 Directly

Veo 3.1 is a Google model, and you can call it directly through Google's own API instead of routing through HiAPI. Per Google's Gemini API pricing page, checked around October 2026, the direct per-second rate is lower than what HiAPI charges: Standard runs roughly $0.40/s at 720p/1080p ($0.60/s at 4K), Fast is around $0.10/s at 720p ($0.12/s at 1080p, $0.30/s at 4K), and Lite is about $0.05/s at 720p ($0.08/s at 1080p, no 4K tier). If the only thing you're optimizing for is the lowest possible per-second rate on this one model, calling Google directly is cheaper.

What HiAPI adds isn't a lower price on this one model — it's consolidation. In practice that means: no separate Google Cloud account, billing setup, or quota approval just to render video; the same API key and the same async task format you're already using for every other model on the platform, across image, audio, and LLM; and pay-as-you-go pricing with no subscription or minimum spend. If you're only ever going to call Veo 3.1 and nothing else, the direct route is worth considering on price alone. If you're mixing Veo 3.1 with other models — swapping in Kling or Seedance for some shots, generating a voiceover, running an LLM to draft the script — one key across all of it tends to save more in integration time than the per-second markup costs.

Estimating Your Cost at Scale

A few concrete numbers to plan around:

• 50 eight-second 1080p clips on Fast with audio: 50 × 8 × $0.25 = $100
• 20 fifteen-second 4K clips on Standard with audio: 20 × 15 × $0.86 = $258
• 200 five-second 1080p previews on Lite, no audio: 200 × 5 × $0.10 = $100

Ways to keep that number down:

• Prototype on Lite, finalize on Standard. Lite's 1080p-no-audio rate is roughly a sixth of Standard's with-audio rate — iterate on framing and motion cheaply, then re-render only the shots you keep at full quality.
• Drop audio when you don't need it. No-audio rates run 40-50% cheaper than the audio variant at the same resolution and tier, across all three tiers.
• Default to 1080p unless 4K is a real requirement. 4K roughly triples the per-second cost over HD on both Standard and Fast.
• Keep clips as short as the shot needs. Cost scales linearly with duration — there's no discount for longer renders.
• Re-check pricing before a large batch. Confirm current rates before committing budget to a big run; they're live figures, not fixed.

FAQ

Is there a subscription or plan for Veo 3.1 on HiAPI? No. HiAPI is pay-as-you-go across every model, including Veo 3.1 — you top up a balance and spend it per task, with no monthly commitment.

Why is Fast or Lite so much cheaper than Standard? They're smaller, faster-rendering variants of the same model family with lower per-second rates. Fast and Lite trade some visual fidelity for speed and cost, and each is suited to different use cases, from quick previews to final-quality output.

Does a more detailed prompt cost more? No. Veo 3.1 pricing on HiAPI is based on output duration, resolution, tier, and whether audio is included — not prompt length or complexity.

Can I use the same API key for Veo 3.1 and other models? Yes. HiAPI uses one key and one async task format across all its models, so switching between Veo 3.1 and, say, an image or audio model doesn't require a new integration.

Takeaways

• Current HiAPI Veo 3.1 rates (live as of October 2026): Standard $0.57/s HD / $0.86/s 4K, Fast $0.25/s HD / $0.60/s 4K, Lite $0.06-$0.14/s (no 4K). Always re-check /en/pricing before a large run.
• You're billed per successful task, not a subscription — idle time and failed renders don't add up on their own.
• Google's own direct API has a lower raw per-second rate for Veo 3.1; HiAPI's tradeoff is skipping a separate GCP setup and keeping one key across every other model you use.
• The cheapest way to work at scale: prototype on Lite or Fast, drop audio when you don't need it, and only render the shots you keep at full resolution and tier.
