Veo 3.1 API Pricing: 8s From $0.075 (Up to 81% Less)

Veo 3.1 costs $0.075–$0.60 per 4-, 6-, or 8-second video on Unifically. For an eight-second 720p video with audio, that is 62.5% to 81.25% below Google's direct Gemini API rate, depending on the tier. Use Lite Relaxed for low-cost drafts, Fast when queue time matters, and Quality for the strongest final output.

TL;DR: Veo 3.1 generates 4-, 6-, or 8-second videos at 24 FPS in 16:9 or 9:16 with synchronized audio. Unifically charges a flat $0.075 for Lite Relaxed, $0.15 for Lite, $0.30 for Fast, or $0.60 for Quality. Google's direct Gemini API charges $0.05/s for Lite, $0.10/s for Fast, and $0.40/s for Standard at 720p. On an eight-second request, the comparable listed tiers cost $0.075 vs $0.40, $0.30 vs $0.80, and $0.60 vs $3.20. See the live rate card or run Veo 3.1.

Update (May 10, 2026): Google deprecated the Fast Relaxed variant. It is no longer available on Unifically. Use Fast for the same output on the standard queue, or Lite Relaxed for the cheapest draft path.

Update (July 18, 2026): Re-verified Google's direct rates against the Gemini API pricing page. Fast now runs $0.10/s at 720p (previously listed here at $0.15/s); Standard holds at $0.40/s. The comparison table below reflects the current numbers, and a new section covers Veo 3 pricing for teams still on the older model.

What is Veo 3.1?

Veo 3.1 is a text-to-video and image-to-video model from Google that generates MP4 videos with synchronized native audio. It launched on November 17, 2025. Google extended it in the Gemini API and Vertex AI in early 2026 with Lite / Fast / Quality variants, Scene Extension, and 4K upscaling.

Each generation accepts a prompt, optional start and end frames on any variant, and optional reference images on Fast, Lite, and Lite Relaxed. The model returns a 24 FPS MP4 in 16:9 or 9:16 with audio in the same file.

What's new in Veo 3.1

Veo 3.1 is the first widely available video model that produces synchronized audio in the same call as the video. Sound effects, ambience, and dialogue arrive already locked to on-screen action. That removes a separate sound design pass for short videos and makes Veo 3.1 a strong default for ad cutdowns, social verticals, and storyboard-to-pitch workflows where audio is the bottleneck.

The 4K preview variant and the dedicated Upscale endpoints also let teams keep raw generation costs low (generate at the cheapest variant, upscale only the videos that survive review), which matters once you generate at production volumes.

What you can do with Veo 3.1

Three generation variants

• Veo 3.1 Lite. Cheapest variant; supports frame mode, reference mode, and voice presets.
• Veo 3.1 Fast. Faster generation with the same input modes as Lite: frame mode, reference mode (up to three images), and optional voice presets.
• Veo 3.1 Quality. Google's top-end output; frame mode only — no reference images — with the highest quality per video.

Lite has a Lite Relaxed counterpart that runs at lower priority for a lower listed price.

Inputs

• Text-to-video. A prompt is enough on every variant.
• Image-to-video (frame mode). Supply a start frame and an optional end frame to bracket the motion. Available on every variant.
• Reference images. Fast, Lite, and Lite Relaxed accept up to three reference images to steer subject and style, with optional voice presets. Not available on Quality, and it cannot be combined with frame mode in the same request.

Extend and Upscale

• Veo 3.1 Extend continues a completed video from its task ID using a chosen base model (Lite through Quality). Useful for narrative cuts longer than a single 8-second generation.
• Veo 3.1 Upscale 1080p and Veo 3.1 Upscale 4K take a finished task ID and return an upscaled MP4. Use them as a final pass on videos that survive review.

Output

• Resolutions: 720p, 1080p, and 4K (4K is preview on Google's side).
• Durations: 4, 6, or 8 seconds per video; chain with Extend for longer narratives.
• Aspect ratios: 16:9 and 9:16.
• Frame rate: 24 FPS.
• Format: MP4 with native audio.

How much does the Veo 3.1 API cost?

Unifically bills the selected Veo tier once per generated video; 4-, 6-, and 8-second requests have the same listed generation price. Google's direct Gemini API bills by output second. This table normalizes both rate cards to an eight-second 720p video with audio. Prices were verified on August 14, 2026 against Unifically's live customer pricing endpoint and Google's official Gemini API pricing.

The labels describe the nearest listed tier, not a claim that every pair has identical latency or output quality. The cost saving grows with duration because Unifically's generation price is flat through eight seconds while Google bills each second.

Two add-on endpoints sit alongside generation:

Generate an eight-second Veo 3.1 video from $0.075.

How much does Veo 3 cost?

Searching for "Veo 3 pricing" (or "veo3 api pricing" — the same question without the space) usually lands you on Veo 3.1 numbers, so here is the older model on its own. On Google's Gemini API, Veo 3 Standard is $0.40 per second, and Veo 3 Fast pricing is $0.10/s at 720p ($0.12/s at 1080p, $0.30/s at 4K). An 8-second Veo 3 Standard video is about $3.20; Fast is about $0.80.

Those are the same per-second rates Google charges for Veo 3.1, so there is no price reason to stay on Veo 3. Veo 3.1 replaced it as the current generation and adds the Lite variant, reference images on Fast, Lite, and Lite Relaxed, Scene Extension, and 4K upscaling. If you are budgeting a new project, price it on Veo 3.1: from $0.075 per video on Unifically, or from $0.40 per 8-second video (Lite, 720p) direct.

How to use Veo 3.1 on Unifically

The API is async: POST a generation, then poll a task endpoint until the MP4 is ready.

const API = 'https://api.unifically.com';
const headers = {
  Authorization: `Bearer ${process.env.UNIFICALLY_API_KEY}`,
  'Content-Type': 'application/json',
};

const start = await fetch(`${API}/veo-3.1-fast/generate`, {
  method: 'POST',
  headers,
  body: JSON.stringify({
    prompt: 'Aerial shot of a coastal cliff at golden hour, gulls circling overhead, waves crashing below',
    aspect_ratio: '16:9',
  }),
}).then((r) => r.json());

while (true) {
  await new Promise((r) => setTimeout(r, 3000));
  const task = await fetch(`${API}/v1/tasks/${start.task_id}`, { headers }).then((r) => r.json());
  if (task.status === 'completed') {
    console.log(task.video_url);
    break;
  }
  if (task.status === 'failed') throw new Error(task.error);
}

Swap the generate path for the variant you want: /veo-3.1-lite/generate, /veo-3.1-quality/generate, /veo-3.1-extend/generate, /veo-3.1-upscale-1080p/generate, or /veo-3.1-upscale-4k/generate. The polling endpoint is the same for every Veo task.

Things to know

• Generating at Quality before iterating. Lock the prompt and framing on Lite Relaxed first. A failed Quality video costs 8x more than a failed Lite Relaxed video.
• Using reference-image mode on the wrong variant. Reference images work on Fast, Lite, and Lite Relaxed. Quality does not accept them — use start / end frame mode there instead.
• Forgetting Extend needs a finished task ID. Extend is a separate endpoint that takes the prior task ID plus the base model. You cannot extend a video that has not finished generating.
• Upscaling everything by default. Upscale 4K is $0.50 per video. Use it as a finishing pass on the videos that survived review, not on every generation.
• Treating 4K as production-locked. Google still labels 4K as preview on Vertex. Expect occasional capacity or quality variance vs 1080p output.

Frequently asked questions

What is Veo 3.1?

Veo 3.1 is Google's text-to-video and image-to-video model. It generates 4 to 8 second 24 FPS MP4 videos at 720p, 1080p, or 4K with synchronized native audio, in 16:9 or 9:16 aspect ratios.

How much does Veo 3.1 cost on Unifically?

Generation runs from $0.075 per video for Lite Relaxed up to $0.60 per video for Quality, with Fast at $0.30. Extend is $0.15 to $0.60. Upscale 1080p is $0.05 and Upscale 4K is $0.50. Check the pricing page for current rates.

How much does Veo 3 cost?

On Google's Gemini API, Veo 3 Standard costs $0.40 per second and Veo 3 Fast costs $0.10 per second at 720p, so an 8-second Standard video is about $3.20. Veo 3.1 charges the same per-second rates direct, which is why new projects should price on Veo 3.1 instead: it starts at $0.075 per video on Unifically.

Does Veo 3.1 generate audio?

Yes. All three Veo 3.1 variants generate synchronized audio (speech, sound effects, and ambience) inside the same MP4 as the video. There is no separate audio call.

What is the longest Veo 3.1 video I can generate?

A single Veo 3.1 generation returns 4, 6, or 8 seconds. To go longer, use Veo 3.1 Extend with the prior task ID and a chosen base model to continue the video.

Which variant should I start with?

Start on Lite Relaxed at $0.075 to lock the prompt and framing — reference images and voice presets already work there. Move to Fast at $0.30 when you need quicker turnaround. Use Quality at $0.60 for the final video, keeping in mind it drops reference-image support.
