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

  • Output at $75.00/1M is among the priciest tracked — output-heavy or reasoning-heavy workloads add up fast.

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 Claude Opus 4's pricing

Two numbers decide most of the bill: $15.00/1M for input (everything you send — prompt, context, attachments) and $75.00/1M for output (everything it generates, including hidden reasoning tokens). Output is priced 5.0× 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.
