Description
Summary
The built-in minimax-m3 pricing row currently uses these USD rates per million tokens:
- Input:
$0.60 - Output:
$2.40 - Cache read:
$0.12 - Cache write:
$0
MiniMax's current pay-as-you-go page marks the 50% discount as permanent. For requests with up to 512K input tokens, the effective rates are $0.30, $1.20, and $0.06. The current row therefore makes usage cost estimates twice the billed amount for the standard context tier.
Official pricing: https://platform.minimax.io/subscribe/token-plan?tab=api-enterprise
The 512K–1M tier uses $0.60, $2.40, and $0.12, but the current pricing table stores only one rate per model. Using the standard ≤512K tier here is consistent with how the catalog handles other models without context-tiered pricing.
Suggested fix
- Change the seed row to
0.30 / 1.20 / 0.06 / 0. - Add a guarded entry to
repair_current_model_pricingthat updates existing rows only when all fields still match the old built-in values. This preserves user-customized prices. - Add tests for a fresh database and for repairing an untouched old row while preserving a customized row.
No database schema change is needed.
