Question: Is there a no-code interface that enables me to add custom actions to my Generative Pre-trained Transformer models?

If you want a no-code interface to let you extend your Generative Pre-trained Transformer models with custom actions, GPT Auth is a good option. The service, which makes GPT apps more secure and useful with a no-code interface, lets you hook your models to outside APIs, manage data and monitor user activity with no programming. Its features include custom actions for creating, retrieving and managing data, and real-time query tracking to monitor user activity.

Another contender is Anakin, an all-purpose AI app foundation that supports a variety of AI models, including ChatGPT. It also offers a no-code app builder to create your own custom AI apps. With more than 1,000 prebuilt AI apps for tasks like content generation and workflow automation, Anakin is a good foundation for customizing your GPT models.

Chariot offers a powerful foundation for building new and modifying existing applications with GPT-3.5 and GPT-4. Although it requires some technical expertise, it offers features for setting up models, managing conversations and processing documents, so it's a good option for developers who want to tap into the power of natural language processing without having to dig too deeply into code.
