Launch discounts: FLUX 3 ended Oct 8, Vidu Q4 runs to Nov 30

Of the two big launches this week, only Vidu Q4's discount is certain to still apply. fal's FLUX 3 Image page, read 2026-10-09, shows a 50% launch price of $0.024 at 1K and says it ends October 8, with $0.048 after. fal's Vidu Q4 image-to-video page shows 30% off until November 30.

What do the two pages say?

Why does the FLUX page still show the promo price?

The page text still lists the launch price on the day after the stated end date. That is a page-copy lag, not proof of what a request is billed. Check the amount on your own invoice or response before you plan a batch on $0.024.

What does the step cost on a batch?

• 1,000 FLUX 3 images at 1K: $24 at the launch rate, $48 at the regular rate.
• 100 Vidu Q4 clips of 10 s at 540p: $31.50 now, $45 after November 30.
• 100 Vidu Q4 clips of 10 s at 4K: $273 now, $390 after.

What does a Sume wallet change?

Neither model is in Sume's catalog code as of 2026-10-09, so there is no Sume rate for them. Sume's rows have no promo clock: the listed models bill provider list x 1.25 (see the Video Router docs and Images docs), for example FLUX.2 Pro at $0.0375 per image and Wan 3.0 at $0.0625 per second at 480p. Plan the comparison on a fixed test set before the promo ends, and re-run it after.

What should I do before a batch on either model?

Run a handful of requests and read the charge on your own account before multiplying. For FLUX 3 that means a 10-image test: $0.24 at the launch rate or $0.48 at the regular rate for 1K, a 2x spread that only the test will settle.

For Vidu Q4 the date is clear but the step is large: every tier rises 42.9% on December 1, so a batch you plan for early December should be budgeted at the regular rates today.

• Write the rate and the date you read it next to every budget line.
• Treat a launch price as a limited offer, not a baseline.
• Keep the regular rate as the planning number and the promo as a bonus.
