Agent Completion: a 15 s MiniMax H3 clip plus voiceover, cap 1.50
A 15-second MiniMax H3 clip at 768p ($1.125) plus a 750-character voiceover ($0.035625) comes to $1.160625, so a cap of 1.5 is enough. Table and body.

A 15-second MiniMax H3 clip at 768p ($1.125) plus a 750-character voiceover ($0.035625) comes to $1.160625 on Sume, so an Agent Completion needs a generation_spend_cap_usd of at least 1.17, and 1.5 leaves room. MiniMax H3 is $0.075 per second at 768p, and TTS is $0.0475 per 1,000 characters.
Line items
Both prices are linear, so the sum is exact.
| Item | Rate | Quantity | Total |
|---|---|---|---|
| MiniMax H3 768p | $0.075 per second | 15 s | $1.125 |
| TTS | $0.0475 per 1,000 characters | 750 characters | $0.035625 |
| Sum | $1.160625 |
Request
Pass the voiceover text as input data so it is not treated as instructions.
{
"instruction": "Make one 15 second MiniMax H3 clip at 768p of a mug, then narrate input.script over it.",
"input": { "script": "..." },
"generation_spend_cap_usd": 1.5
}Limits and gotchas
Joining the voice to the clip is not a separate priced line in this table, so confirm the final bill from the run's usage.
