Cheapest AI video generator with audio (2026): every verified native-audio rate, ranked
Native audio (dialogue, sound effects and music generated with the video) saves an editing pass, but most tools charge extra for it. This page ranks only rates whose official price includes generated audio (128 of the 237 rates in ClipCost’s calculator), per second and per usable 30-second clip, and shows what switching audio on adds for the 36 models priced both ways.

Quick answer
Cheapest with audio: Grok Imagine 1.5 Lite · 480p, audio on (xAI API) at $0.02/sec = $1.80 per usable 30s (#1 of 237 — the cheapest rate overall, audio or not). Cheapest 720p with audio: Grok Imagine 1.5 Lite · 720p, audio on (xAI API) or LTX-2.3 Fast · 720p, audio on (LTX API) = $2.70. Cheapest 1080p with audio: LTX-2.3 Fast · 1080p, audio on (LTX API) = $5.40 (#51=). Cheapest on a subscription: Seedance 2.0 Mini · 480p (via Luma) = $2.70. What audio adds: a median +41% (1.41×) over the same model silent, from +20% (Veo 3.1 Fast) to double (Veo 3.1 Standard, Kling 2.6, Wan 2.6 Flash). Prices checked Nov 12, 2026.
Basis: usable = 3 attempts (1 + 2 retries), the same as the calculator. Plan-credit rows assume you use every credit on the cheapest annual plan that includes the model; API rows are pay-as-you-go. “Audio” = the official price is stated for output with generated audio (“Either” = same price with or without it). 69 ranked rates whose pricing page does not say whether audio is included are left out rather than guessed. Ranks are site-wide across all 237 ranked rates. Cost only, not quality.

What audio adds to the price, model by model
Same model, same storefront, same resolution, priced once with generated audio and once without. Sorted from smallest to biggest premium. The cheapest silent rate ClipCost ranks, PixVerse V6 · 360p, audio off (PixVerse API) at $2.00, actually costs more than the cheapest rate with audio ($1.80), so audio does not always mean a higher bill.
Median premium across all 36 pairs: 1.41×. Veo 3.1 Fast (+20%), PixVerse V6 Max 540p (+22%) and Kling 3.0 inside Luma at 1080p (+23%) add the least; Kling 2.6, Veo 3.1 Standard, Wan 2.6 Flash and Veo 3.1 inside the Runway app charge double for audio.
Not ranked yet
- Pika H3 Flex (768p, audio always on): 10 Pika credits per 5s = 2 credits/sec, about $2.40 per usable 30s on Pika Starter annual credits (not ranked (would be ~#6)). Checked this morning on Pika’s pricing page; Pika’s own models are page-only until the Pika plan change is folded into the ranking. See Pika 2.5 and Pika H3 Flex cost.
- “Audio not stated” rates: 69 ranked rates (for example the MiniMax H3 API, Seedance 2.0 API, Ray3.2 and several Runway partner models) have no audio statement on the official price list, so they are not counted as audio rates here. See MiniMax Hailuo cost and Seedance 2.0 cost.
Which to pick (on cost)
- Cheapest drafts with sound: Grok Imagine 1.5 Lite on the xAI API ($1.80 at 480p, $2.70 at 720p). See Grok Imagine cost.
- 1080p with audio on a budget: LTX-2.3 Fast ($5.40); LTX-2.3 Pro 1080p is $7.20. See LTX API pricing.
- Google with audio: Veo 3.1 Lite 720p ($4.50) or Veo 3.1 Fast 1080p ($10.80, only 20% over silent). See Veo 3.1 variants.
- Kling with audio: Kling 3.0 720p in the Kling app ($8.10), 1.5× the silent price. See Kling 3.0 cost and where Kling is cheapest.
- Want separate control over the soundtrack: generate silent and add audio in editing — the cheapest silent rate is $2.00 (PixVerse V6 · 360p, audio off (PixVerse API)). See PixVerse cost.
Honest flags
- “Audio” comes from each row’s official price label or audio column (for example Luma’s pricing table marks Seedance 2.0 Mini and MiniMax H3 Max “Audio: Yes”). ClipCost compares cost only, not audio quality, lip-sync or language support.
- Plan-credit prices need a paid plan and assume you use all credits; API prices are pay-as-you-go. Pika’s plan credits changed on Nov 12, 2026 (Starter 900 → 600); ranked Pika rows still use the Nov 1 plan and none of them states audio, so they are not in the tables above.
- Gemini Omni Flash rows do not state audio and are not counted here; Google bills Omni 1.1 at the 1.2 rate from Dec 3, 2026. Runway’s 25% Kling 4.0 promotion ends Nov 30, 2026.
