In a Databricks experiment, the Opus model was cheaper to operate than the Sonnet model because Sonnet required more iterations and reasoning to achieve the same results.

In a Databricks experiment on coding tasks, the Sonnet model cost $2.09 per task, while the Opus model, which is more expensive per token, cost only $1.94 per task.

In March, Anthropic released the Claude 3 family of models, which includes Haiku (small, fast, cheap), Sonnet (medium), and Opus (large, most capable).
