Where Claude Opus 4.1 fits

Claude Opus 4.1 is the most expensive model on the gateway at $15.00 per 1M input and $75.00 per 1M output tokens, positioned for work where a retry costs more than the tokens.

Pick it when

• A single hard reasoning step is blocking a pipeline and a wrong answer is genuinely expensive.
• You are validating a smaller model’s output on a sample of cases rather than running it in production.
• You need the strongest Anthropic model available for a narrow, well-specified job.

What to watch

• Output is 25 times the input price, so an unbounded generation can dwarf everything else in your monthly spend.
• For most production traffic Sonnet 4.5 or Haiku 4.5 returns a better cost per resolved task.

Best for: Escalation paths, hard evaluation cases and one-off analysis where quality is the only constraint.
