For years, PostgreSQL has been one of the most critical, under-the-hood data systems powering core products like ChatGPT and OpenAI’s API. As our user base grows rapidly, the demands on our databases have increased exponentially, too. Over the past year, our PostgreSQL load has grown by more than 10x, and it continues to rise quickly.
TL;DR
- PostgreSQL is a critical, under-the-hood data system for OpenAI products like ChatGPT and their API.
- Database demands have increased exponentially due to rapid user base growth.
- PostgreSQL load has grown by over 10x in the past year and is still rising.
