Prices as each provider's official pricing page states them, confirmed Sep 18, 2026. No subscription: you pay for the seconds generated. Prices exclude tax.

How the status is checked

Whether a model still runs is checked separately from prices: prices change monthly, but a model can disappear between two price syncs, quietly making every page that mentions it wrong. So each model record has its own confirmation date and review deadline; overdue records are flagged, never assumed to still be running.

Last confirmed on Sep 25, 2026; due to be rechecked by Oct 25, 2026.

Recommended Alternatives & Budget-Friendly Picks

Based on the same model category (Video generation), public specs, and availability across channels, here are recommended alternatives:

Kling 3.0 Kling
Top Tier (Elo 1135) 4K With audio

A third-party model listed on both Luma's and Runway's official pricing pages. Luma publishes a per-second rate; Runway lists it in its plans, but part of Runway's rate table sits behind "View more", and the page we read has no rate for this model. Kling's own site lists it as the “Kling 3.0 Model Series”, made up of two models, VIDEO 3.0 and VIDEO 3.0 Omni. Credits per second on Kling's international web membership (kling.ai) were read from the generation page's official quote after signing in on Sep 19, 2026, and are linear in length.

MiniMax H3 MiniMax
Top Tier (Elo 1125) 2K

A video model from MiniMax (the company behind Hailuo), listed in Luma's official rate table. Audio is included by default, up to 1440p (2K). It is the default model in the generator on Hailuo's own homepage, and PixVerse's site has a page for it too.

Model Details
Seedance 2.5 ByteDance
1080p With audio

ByteDance's video model, listed on the official pricing pages of Luma, Runway and InVideo AI. Luma publishes a per-second rate that includes audio by default; Runway lists it in the Pro plan, with no rate on the page we read; InVideo AI offers it from the Plus plan up and gives only an approximate cost, which we don't use as an exact rate. Pika's official pricing page lists it too: 122 credits per 5-second clip at 720p. PixVerse's site has a page for it too.
