The world of AI is moving at a rapid speed and there are now a number of different AI generators out there - from AI image generators to AI video generators, and a whole bunch more! It's easy to get bogged down with all these options. To make learning about these generators easier, we here at GoAPI have put together an easy-to-understand summary of the most popular AI generators, covering their purpose and functions.
The Canvas of the Future - txt2img
Text-to-image is a machine learning model which enables the process of typing in a few words (known as 'prompts') to generate images from photorealistic depictions to remarkably creative artworks. Now let's take a look at the 3 most popular txt2img AI image generators of late.
First revealed by OpenAI in a blog in January 2021, DALL-E represented a significant milestone for AI generators. DALLE is the multimodal (i.e. able to produce different modes of outputs, such as text, or images) implementation of GPT-3, with approximately 12 billion parameters. For the first time, we could generate visuals with mere textual inputs.
Not long after DALL-E, OpenAI introduced an improved model: DALL-E 2. With only 3.5 billion parameters (smaller than DALLE), this new model was designed to generate images with enhanced quality and a higher degree of realism, and it is able to edit existing images or expand upon it.
In an academic paper named 'Improving Image Generation with Better Captions', the OpenAI released with it the DALL-E 3 model, representing the best text-to-image model released by OpenAI so far, in terms of prompt-following, coherence, and aesthetics compared to previous models and competitor models.

Midjourney is another text-to-image generator founded by David Holz (who co-founded the hand/finger motion tracking company Leap Motion). Midjourney's beta service first started on July 12th, 2022. Since then, the company has focused on refining their algorithms, bringing forth updated and superior models every few months. Midjourney's latest version V6 was said to have been trained over a 9 month period, and it is promised to deliver heightened realism and more literal renditions of user prompts.

Out of the all the text-to-image models covered in this article, Stable Diffusion is undoubtedly the most versatile, and the only open source model. Released in 2022 by Runway, CompVis, and Stability AI, Stable Diffusion is a latent diffusion model that can run on most consumer GPU with at least 4GB of VRAM. Another major advantage is Stable Diffusion allows for end-user fine-tuning using specifically collected dataset provided by the user, and will generate precise, personalized outputs following the training images.

Revolutionising Visual Media - txt2vid
Building on the advances from text-to-image models, text-to-video models take the generative AI capability one step further, aiming to significantly reduce the video production workflow by employing various types of machine learning model that translates natural language descriptions into corresponding visuals in the form of a video. Below we are going introduce two popular products in this space.
Runway is a private U.S. based company who is the forefront leader in the text-to-video space. They released their Gen-1 model in 2023 February which is also based on diffusion models. Gen-2 came shortly after and became the first commercially available text-to-video model, producing new videos in a realistic and consistent manner using just textual inputs.
This AI video generator by Runway does have some limitations. For one, the videos produced don't have any sound. Plus, the movements in the videos can be somewhat limited. However, it's important to bear in mind that the field of AI generators is still in the relatively early stages of development. Considering those factors, Runway's model has done a pretty commendable job thus far.
Pika Labs is relatively new to the text-to-video space, publicly annoucing its $55M USD of series A funding round in November 2023. With more than 500k users in its Discord channel, the #pikalabs hashtag has generated nearly 30 million views on Tik Tok alone. Pika can turn your text into visually engaging videos, eliminating the need for complicated video editing tools and long production times. It's an easy-to-use tool that transforms your ideas into captivating video content. Just type your text and watch as the AI generation takes place.
Models such as DALL-E, Midjourney, Stable Diffusion, Runway's Gen-2, and the Pika Labs platform are shining examples of the intersection between technology and creativity. At GoAPI, we adapt and innovate to make these advanced AI generator APIs accessible and user-friendly, making the digital transformation easier for you. As of now, we currently already provide DALL-E 3, Midjourney, Stable Diffusion, and other LLM API's, and we are working to bring more APIs function to our developers such as such as ChatGPT Plus BYOA and txt2vid APIs. Stay tuned!
