Not sure which one to pick?
For most tasks, we recommend Claude 4 Sonnet or GPT-4o. Both are capable general-purpose models with different response styles.
For particularly complex tasks, Claude 4 Opus and o3 offer higher reasoning capabilities. o3 performs well on math, science and coding problems. Claude 4 Opus handles complex coding tasks and longer-form writing. Both process more slowly than other models.
GPT-4o mini is a lighter, faster alternative when other models aren't available.
