Question: Is there a unified AI interface that supports various content types like text, images, videos, and audio, and offers a pay-as-you-go pricing system?

If you're looking for a single AI interface that can handle different types of content, including text, images, videos and audio, with a pay-as-you-go pricing model, Blend AI is a good choice. The single interface gives you access to a range of AI models, including image, video and audio, without a monthly subscription. Blend AI charges you for the resources and features you use, so it's a good option for those who want flexibility and don't want to break the bank. The interface also includes a multi-modal graph interface, conversational AI and model chaining that can be useful for real-time interactions and specific results.

Another good option is Eden AI, an orchestration service that lets you integrate multiple AI models into your business workflow. Eden AI provides a single interface to a range of AI services, including generative AI, translation, text analysis, image analysis and more. The service charges by the hour or by the month, with different pricing tiers depending on how much you need. That can be good for companies that want to automate operations and reduce costs without sacrificing performance.

For a no-code approach, MindStudio is a flexible foundation for building custom AI tools and automations. You can assemble AI models from different sources into custom assistants without having to write any code, and the service charges tiered pricing starting at $1 per 1 million tokens. That's a good option for those who want flexibility and customization.

Last, Magai is an all-in-one AI service that aggregates many different AI tools, including ChatGPT and others, into a single interface. It can handle a variety of actions, including uploading files, reading web pages and transcribing YouTube video. Magai's pricing starts at $19 per month for the Personal+ plan, so it's a good option if you want to manage and consume AI-generated content.
