Show HN: Free tool to migrate OpenAI Assistants (migratetoresponses.com)

A new tool has been launched to assist developers in migrating their existing projects from OpenAI's Assistants API to the upcoming Responses API, which will become the standard following the sunset of the Assistants API on August 26, 2026. This user-friendly solution allows developers to simply paste their current Assistants API code, and in a matter of seconds, receive production-ready code for the Responses API, complete with explanations of the adjustments made. The first migration is offered for free, with a one-time fee of $9 for unlimited use thereafter. This migration tool is particularly significant for the AI/ML community as it addresses the needs of approximately 600,000 projects relying on the Assistants API, facilitating a seamless transition to newer, more powerful capabilities in the Responses API. By making this migration process straightforward, developers can quickly adapt to changing technologies, ensuring their applications remain functional and up-to-date. The tool’s ability to analyze API calls and offer equivalent mappings also enhances knowledge sharing within the community, potentially improving overall code quality as developers understand the nuances of the new API.
