Where it fits

  • Multimodal prompts — accepts image input alongside text.
  • Quality-first tasks where capability matters more than rate — a first-party flagship rather than a budget pick.

Watch for

    These notes are derived from price, context and modality — structural facts, not measured quality. Measured cost-to-finish-a-task lives on the real-cost index.

    How to read o4 Mini's pricing

    Two numbers decide most of the bill: $1.10/1M for input (everything you send — prompt, context, attachments) and $4.40/1M for output (everything it generates, including hidden reasoning tokens). Output is priced 4.0× the input rate here, so the shape of your workload — how much it reads versus writes — matters as much as the headline figure. This is the provider's first-party list price, reconciled against the routed market each run.
