# Generation Settings

Generation settings control how Ideogram interprets a prompt and returns image results. Start with [Available Models](/using-ideogram/generation-settings/available-models.md) for Ideogram 4.0 and current model compatibility, then adjust the settings that are available for your selected model, plan, endpoint, and workflow.
