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.

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.

  • usage.generation_spend_cap_usd_micros echoes your cap on the receipt.
  • next_action stays poll_status until the run ends.
  • Cancel with POST /v1/agent-runs/{id}/cancel if the instruction was wrong.
