API pricing is $0.15 per million input tokens, $0.60 per million output tokens and $0.015 per million cached input tokens. One million uncached input tokens plus one million output tokens costs $0.75. Sources: MiniMax

Thinking cannot be disabled, and reasoning effort defaults to max. Higher effort increases output tokens and latency. Sources: MiniMax

Output throughput alone does not establish first-token inference latency or total workflow time for coding agents. Cost per completed task depends on correctness, total token consumption and retries. Sources: MiniMax

Why it matters

M3.1 Flash gives developers API and subscription access for coding tools. Mandatory reasoning makes effort settings consequential for cost and latency, while faster token generation alone does not establish faster workflows.
