OpenAI’s GPT Store, where users can share their custom chatbots, finally launched Wednesday after a monthslong delay. The store brings more potential use cases to ChatGPT and expands OpenAI’s ecosystem beyond what the company builds for customers. Since announcing the GPT Builder program in November, OpenAI said more than 3 million bots — called GPTs — have been created by users. (Yours truly included; I made a GPT that suggests synonyms for common words). The company said it plans to highlight useful GPTs weekly inside the store.
