Runway's two Omni Flash ids: 10-11 credits vs 3.4-30 for 1.1

Runway sells two Omni Flash ids: gemini_omni_flash at 10 to 11 credits a second and gemini_omni_flash_1.1 at 3.4 to 30. The 1.1 id is cheaper at low resolutions and dearer at 4K. Sume lists only gemini-omni-flash-1.1.

The two ids

At $0.01 per credit, from the Runway pricing page:

How to choose

• Drafts and tests: 1.1 at 360p at 3.4 credits is about a third of the older id's rate.
• Final renders at 4K: 1.1 costs 30 credits a second, nearly three times the older id.
• If you do not need Omni's new features, compare the output at the resolution you will ship, not the headline price.

Sume's side

The Sume catalog carries the 1.1 model only: 3 to 10 seconds, 360p, 720p, 1080p and 4K, 16:9 or 9:16, audio always on. I found no older Omni Flash id in the video catalog. Sume bills Google's list times 1.25, so a 720p second is $0.125.

Where the break-even sits

From the Runway page I have only the two ends of the 1.1 range, 3.4 credits at 360p and 30 at 4K, and the older id's 10 to 11. So the break-even lies somewhere between those resolutions, and I cannot place it exactly. At the low end 1.1 is under a third of the older rate; at the top it is nearly three times higher.

If you use the Runway API, price a test at the resolution you ship before choosing an id, and read the pricing page again on the day you run a large batch, since credit tables change. On Sume the question does not arise, because only the 1.1 model is listed.
