Twenty 8-second vertical teasers after Sora: $16 to $33.60 by model

Twenty 8 second vertical product teasers cost $20.00 on gemini-omni-flash-1.1 or wan-3.0 at 720p, $16.00 on minimax-h3-max at 768p, and $22.40 on kling-3 with audio off. With kling-3 audio on, the same twenty are $33.60. All figures are Sume's billed price, list times 1.25.

The job

A common Sora use was a batch of short vertical clips for a product line. OpenAI's deprecations page records the Videos API shutdown on September 24, 2026 with no replacement listed, so the batch has to move to another id. Here are the numbers for that move.

Cost by model

Every figure above is billed price for exactly 8 seconds. A 6 second version of the Omni row is 6 x $0.125 = $0.75 per clip, $15.00 for twenty. Shorter teasers are the simplest way to cut cost without changing model.

What the price leaves out

The cheapest row is not automatically the right one. minimax-h3-max reaches 1080p only as a latent refinement of 768p, and Kling's price depends on the audio switch. Wan offers a cheap 480p draft at $0.0625 per second, which makes twenty 8 second drafts $10.00.

Two passes

Run the batch in two passes. Draft all twenty at 480p on Wan for $10.00, pick the ones that read, and re-render only those at 720p or 1080p. If you keep half, the second pass costs $10.00 at 720p, so the whole job lands at $20.00, the same as rendering all twenty once, with ten ready finals you chose.

Request details

Aspect ratio 9:16 is supported by Wan, Kling and Omni in the catalog. Send aspect_ratio on the request; do not send size or seed, which return 400. Give each clip an Idempotency-Key so a retry does not reserve twice, using the curl and xargs recipe.

If the teasers need sound, check the audio rules per model before you compare totals: Omni and minimax-h3 have native audio, while Kling's price changes with the audio switch, as the last two rows show.

Balance

Billing reserves the amount at submit and releases it on failure, so twenty jobs in flight hold up to the full total. Check your balance against the table before launching, and see credits and errors for the 402 case.
