How much does AI video generation cost per second in 2026?

Between $0.015 and $0.50 per second of output video. Replicate-hosted open-weight models (LTX, Hunyuan) cost $0.015–$0.02/sec. Mid-tier (Runway Gen-4 Turbo, Pika Turbo, Hailuo Lite) costs $0.025–$0.07/sec. Premium (Sora 2 Pro, Veo 3) costs $0.30–$0.50/sec.

Is Sora 2 worth the price over Runway Gen-4?

For most production use cases, no. Sora 2 Pro at $0.50/sec is 10× Runway Gen-4 Turbo at $0.05/sec. Sora's advantage is longer coherent clips (up to 20 seconds vs 10) and slightly better physics. For 5-second social media clips, Runway Gen-4 or Kling 2 deliver 90% of the quality at 10% of the cost.

What is the cheapest AI video generator in 2026?

Replicate-hosted LTX Video at $0.015/sec, or self-hosted Hunyuan Video on a rented H100 at roughly $0.008/sec amortized. For commercial-quality output, Pika Turbo ($0.025/sec) and Hailuo Lite ($0.04/sec) are the cheapest production-grade options.

How long can AI video clips be in 2026?

Maximum clip length ranges from 5 seconds (Pika Turbo, Replicate open-weight) to 60 seconds (Veo 3). Most production-grade models cap at 10 seconds — Runway Gen-4, Kling 2, Pika 2.0, Luma. For longer videos, generate multiple clips and concatenate.

Does Veo 3 generate sound?

Yes. Veo 3 is the first major model with native synchronized audio generation — dialogue, sound effects, and ambient sound generated together with video. Other models require a separate TTS or sound-effect pass, adding $0.05–$0.15 per clip in audio costs.

Why does video generation cost so much more than image generation?

A 5-second video at 24 fps is 120 frames — each frame is roughly an image. So generation cost scales linearly with duration. At $0.10/sec for Runway Gen-4, a 5-second clip is $0.50, equivalent to generating 120 images. Modern video models also use temporal coherence layers that add ~30% compute overhead per frame.

How much does it cost to generate AI video in 2026?

Cost per second of output video, sorted cheapest first:

Model	Cost/sec	Max length	Resolution	Notes
Replicate LTX Video	$0.015	5s	720p	Per-second compute
Replicate Hunyuan Video	$0.02	5s	720p	Per-second compute
Pika Turbo	$0.025	5s	720p
MiniMax Hailuo Lite	$0.04	6s	720p
Runway Gen-4 Turbo	$0.05	10s	720p
Pika 2.0	$0.06	10s	1080p
Kuaishou Kling 1.6 Std	$0.07	10s	720p
Runway Gen-4	$0.10	10s	1080p
MiniMax Hailuo 02	$0.10	6s	1080p
Google Veo 3 Fast	$0.10	30s	720p
Luma Dream Machine 1.6	$0.15	10s	1080p
Kuaishou Kling 2.0	$0.20	10s	1080p
Luma Ray 2	$0.25	10s	1080p
OpenAI Sora 2 Standard	$0.30	15s	720p
Google Veo 3	$0.35	60s	1080p	Native audio
OpenAI Sora 2 Pro	$0.50	20s	1080p

A 10-second clip from Runway Gen-4 costs $1.00. The same clip from Sora 2 Pro costs $5.00. That's the practical decision point — when is the Sora 2 result 5× better than the Runway Gen-4 result? For most production use cases in 2026, it isn't.

Which AI video model should you actually use in 2026?

Decision tree by use case:

Social media clips (5–10s, vertical, lots of variations) — Pika Turbo at $0.025/sec or Hailuo 02 at $0.10/sec. High volume, fast iteration matters more than perfect quality.
Marketing / ad creative (5–15s, polished) — Runway Gen-4 at $0.10/sec or Kling 2.0 at $0.20/sec. Strong commercial output, fast turnaround.
Cinematic / film (any duration, premium quality) — Sora 2 Pro at $0.50/sec or Veo 3 at $0.35/sec. Pay for longer coherent shots and physics realism.
Music videos with sync sound — Veo 3 wins by default. Native audio means no separate TTS or sound-design pass.
Product demos (5–10s, talking head + product) — Hailuo 02 or Runway Gen-4. Good face consistency at moderate cost.
Experimentation / preview — LTX Video on Replicate at $0.015/sec. Fast iteration; upgrade chosen winners to a premium model for finals.

The common 2026 stack mirrors image generation: generate candidates with a cheap model, finalize with a premium model. Generate 5–10 variations with Pika Turbo ($0.025/sec × 5s × 8 variants = $1.00), pick the winning concept, regenerate with Veo 3 or Sora 2 ($0.35/sec × 5s = $1.75 final). Total $2.75 versus going straight to Sora 2 with 8 candidates ($20).

Why is video generation so expensive?

Three reasons compound:

Each frame is roughly an image. A 5-second clip at 24fps is 120 frames. At Runway Gen-4 pricing of $0.10/second, you're paying ~$0.50 for those 120 frames — about $0.004 per "frame-image". That's competitive with low-end image generation.
Temporal coherence adds compute. Video models use attention layers across frames to keep objects, lighting, and characters consistent. This adds 30–50% compute overhead versus pure image generation.
Resolution scales hardware cost quadratically. 1080p has 2.25× the pixels of 720p, and video models scale compute roughly with pixel count × frame count.

Practical implication: dropping from 1080p to 720p saves ~50%, often imperceptible for social media playback. Dropping from 30fps to 24fps saves another ~20%. Many providers default to 30fps but bill as if you used the full count — verify your provider charges by actual_fps × duration, not headline duration.

What hidden costs come with AI video?

Six line items frequently forgotten:

Audio generation. Most models output silent video. A 5-second clip needs $0.05–$0.10 in TTS (ElevenLabs, Cartesia) plus $0.05–$0.20 in sound design (AudioGen, Stable Audio). Only Veo 3 generates native audio.
Upscaling. 720p clips need upscaling for YouTube/web. Topaz Video AI runs ~$0.02/second of output. Total cost: $0.07/sec instead of $0.05/sec.
Frame interpolation. 24fps → 60fps for smooth playback. RIFE or AICP costs ~$0.01/sec.
Failed generations. Average 1.5–2× retry rate before getting a usable shot. Budget 1.7× the headline rate.
Storage and egress. Video files are big — 100MB per 1080p 10-second clip. At scale this is real money: 10k clips/month = 1TB storage + significant egress.
Subscription minimums. Runway Pro is $35/month minimum; even one second counts. Plan around these floors.

Should I self-host video generation?

Self-hosting math is harder than for images because video generation is memory-bound, not compute-bound.

Hunyuan Video needs ~60GB VRAM at 720p 5s output → minimum H100 80GB.
Open-Sora 2.0 needs ~50GB VRAM at 720p → H100 PCIe is the floor.
Mochi needs 32GB VRAM → A100 40GB works.

At RunPod H100 SXM pricing of $2.99/hour, a single H100 can produce roughly 60 seconds of 720p output per hour for Hunyuan Video (slow!). That's $2.99 ÷ 60 = $0.05 per second amortized.

Compare to Replicate Hunyuan at $0.02/sec hosted. Self-hosting only wins if you have very high volume (>2 hours of generated video per day) AND are willing to manage the queue, retries, and model updates. For most teams, hosted APIs are 2–3× cheaper than rented self-host capacity once you factor in idle time.

What is the quality leaderboard for AI video in 2026?

Based on May 2026 community evaluations:

Overall realism: Veo 3 and Sora 2 Pro tied. Both can produce 10+ second clips with consistent physics.
Motion quality: Kling 2.0 wins for human motion. Runway Gen-4 wins for camera motion.
Text-to-video adherence: Sora 2 wins for literal interpretation of complex prompts.
Image-to-video (animating a still): Runway Gen-4 and Luma Ray 2. Best at preserving the input image's style.
Lip sync / talking heads: Hailuo 02 surprisingly strong for the price. Sora 2 Pro best overall.
Speed: Pika Turbo and Hailuo Lite under 30 seconds wait time. Sora 2 Pro and Veo 3 can take 2–5 minutes per clip.

Quality rankings rotate quarterly — by Q3 2026 expect at least 2–3 of these top spots to change hands as new models ship.

How often does video generation pricing change?

Every 2–4 weeks for proprietary models, weekly for open-weight hosted services. Pika dropped Turbo from $0.05 to $0.025 in three months. Sora 2 Pro launched at $1.00/sec and dropped to $0.50 in five weeks.

We re-verify pricing on the Video Generation Cost calculator the first of every month. For volatile periods around major model launches (Sora 3 expected late 2026, Veo 4 in Q3), re-check mid-month.
