Omni Flash rejects 768p: the resolution strings each video model takes

Sending 768p to Gemini Omni Flash 1.1 fails, because Omni prices only 360p, 720p, 1080p and 4K, while MiniMax H3 prices 480p, 768p, 2K and 4K. The price check says so in words: Cannot price resolution: expected 360p, 720p, 1080p, or 4K.

The table below lists the accepted strings for the four models in this lane and the per-second range of each, from $0.0375 on Omni 360p up to the top row (Sume price tool, read 2026-10-09).

Accepted resolutions and per-second range

The match is case-aware for the K tiers: the pricing code accepts 4K and the lowercase 4k as an alias on Omni, and 2K/4K or lowercase on H3.

Where the near-misses come from

The cheapest fix for a near-miss is to read the allowed list from the catalog before you build the request.

• 720p sent to MiniMax: use 768p. MiniMax 768p is native and first-class, not a 720p.
• 1080p sent to MiniMax H3: H3 has no 1080p row, so use H3 Max.
• 768p sent to Omni: use 720p (or 1080p).
• 480p sent to Recast: Recast takes 768p or 1080p and defaults to 768p.

Read the list instead of guessing

GET /v1/videos/models returns supported_resolutions and supported_durations for every video model. Compare your request to those lists in your own code and you avoid the round trip.

import os, requests
r = requests.get("https://api.sume.com/v1/videos/models",
                 headers={"Authorization": f"Bearer {os.environ['SUME_API_KEY']}"}, timeout=30)
r.raise_for_status()
for model in r.json()["data"]:
    if model["id"] in ("gemini-omni-flash-1.1", "minimax-h3", "minimax-h3-max"):
        print(model["id"], model["supported_resolutions"])

The same 8 seconds, four ways

The clearest way to see the ladders is to price the same 8 seconds at the nearest resolutions. Omni has no 768p and MiniMax has no 720p, so 720p and 768p are different rows on different models.

Limits and gotchas

A 2K or 4K request to MiniMax H3 is priced, but it is an upscale of native 768p, not a native render. Omni 4K is its own tier at its own price.
