OpenAI has released new capabilities for its user base, including custom versions of ChatGPT called GPTs that can be built directly within ChatGPT's interface. These GPTs can be tailored to specific purposes and can access web browsing capabilities, DALL·E's image generation tool, and a code interpreter function. Additionally, OpenAI has released the Assistants API, which enables users to build assistants directly within their own applications. Unlike GPTs, which require no code, assistants are hosted by the user and require coding for integration. The Assistants API allows developers to pull AI assistants into their apps and configure them to respond to user queries by leveraging tools and files. This new feature is integrated with Zapier's ChatGPT integration, enabling users to build custom assistants that perform actions across various apps, such as Slack, Google Calendar, and Gmail.
