| Migration | Fast cost tier for users moving down from Sonnet. | Use Opus 4 selectively for premium reasoning and coding workloads that justify the cost envelope. | Use when Sonnet is insufficient and maximum reasoning depth matters more than cost. | Best default Anthropic family when Opus is too expensive and Haiku is too small for the workload. | Current recommended Anthropic default unless Opus depth is required. | Default Cohere family for new general-purpose production workloads. |
