On June 16, 2025, OpenAI Developers announced that prompts are now an API primitive, allowing developers to centrally manage, version, and optimize prompts for use across the Playground, API, Evals, and Stored Completions. The feature targets developers working with OpenAI’s platform and benefits those who previously adjusted prompts through manual copying. The Prompt object is now available in the API and SDKs and enables prompts to be preconfigured with settings such as tools, models, and messages. The Playground now features an Optimize tool to suggest refinements, and “presets” have been replaced by the ability to save and share prompts, including all versions and configurations.

Prompts are now reusable and versioned resources within the OpenAI Platform. They can include variables, templates, and rollback support. Prompts synchronize across all relevant tools, including Evals, to make testing and iteration repeatable and consistent. Developers can use a Prompt ID to reference the latest published version or specify a fixed version. The Optimize tool provides suggestions for clearer, more direct language in prompt creation.

OpenAI’s update is part of its continued focus on improving developer workflow and usability. The changes, such as the revamped Prompts Playground and prompt evaluation features, respond to industry demand for structured prompt management. This reflects OpenAI’s commitment to supporting efficient prompt deployment and matching similar moves within the field.
