Veo 3.1 vs Luma Ray3.2: specs, HDR, audio and price

Specs side by side

Luma figures come from Luma’s announcement, API guides and product pages; Veo figures from Google Cloud. Luma doesn’t publish a reference-image limit, so the table says so.

A few Ray3.2 details sit outside the table. Resolutions run 360p (a draft mode), 540p, 720p and 1080p. Aspect ratios are 9:16, 3:4, 1:1, 4:3, 16:9 and 21:9, against Veo’s 16:9 and 9:16. Luma’s marketing pages say 16 keyframes and its API docs say 64, so check the limit for your route. Extend works on standard (SDR) clips only, and Modify Video edits clips up to 20 seconds long.

What it costs

Luma’s API lists $0.003 per credit as its default list rate (contracts can differ). A 5-second clip costs 100 credits at 720p and 400 at 1080p. Because Ray3.2 is silent, compare it with silent Veo. Google’s Veo prices are per “count”, which we read as one second:

At 1080p, Ray3.2 on Luma’s API costs more than silent Veo 3.1 Quality and more than silent Veo 3.1 Fast on Google Cloud. At 720p it costs more than silent Veo 3.1 Lite, less than silent Fast and less than silent Quality. Through imaginary.app, Veo costs more per second than Google Cloud’s list price; you pay for not setting up a Cloud project. Our full credit table for every Veo 3.1 setting is on the Lite vs Fast vs Quality page.

Plans

Luma’s app plans are monthly: Plus $30 (10,000 credits), Pro $90 (40,000 credits), Ultra $300 (150,000 credits). Luma’s pricing page lists no free plan but mentions free trial credits. App credits may not map one-to-one to API credits, so we don’t convert them to seconds. imaginary.app sells one-time packs from $9.99; see the pricing page or the cost calculator.

When to choose Veo 3.1
