ETRI’s KOALA Model: A Game-Changer for Ultra-Fast AI Image Generation

A revolutionary new generative AI model has been developed that can create high-resolution images from just a text description in a mere two seconds. This breakthrough in artificial intelligence has the potential to significantly impact various industries, including creative services, content production, and education.

In Short:

1. ETRI has developed an ultra-fast generative visual intelligence model, known as the ‘KOALA’ model, that can create images from text inputs in just 2 seconds.
2. It has managed to reduce the model’s size considerably and increase the generation speed.
3. The ‘KOALA’ model is significantly faster than other models in the market.

What is the ‘KOALA’ Model?

The ‘KOALA’ model is a fast text-to-image model developed by the Electronics and Telecommunications Research Institute (ETRI). It uses a technique called knowledge distillation to compress the U-Net of the Stable Diffusion XL (SDXL) model. The KOALA-700M model can generate a 1024×1024 image in less than 1.5 seconds on an NVIDIA 4090 GPU, which is more than 2x faster than SDXL. This model offers a balance between speed and performance, making it a cost-effective alternative to SDXL in resource-constrained environments.

What is ETRI?

The Electronics and Telecommunications Research Institute (ETRI) is a South Korean government-funded research institution. Established in 1976, ETRI has been at the forefront of technological excellence for over 40 years. It is one of the leading research institutes in the wireless communication domain with more than 2,500 patents filed. ETRI strives to advance science by formulating innovative ideas, developing new techniques, and training professional individuals in the area of information telecommunications.

How Does the KOALA Model Work?

The ‘KOALA’ model, developed by ETRI, is a breakthrough in AI image generation. It works by significantly reducing the parameters from 2.56 billion of the public SW model to 700 million using a technique called knowledge distillation. This reduction in parameters leads to fewer computations, thus decreasing processing times and operational costs. The model size is reduced by a third, which improves the generation of high-resolution images, making it twice as fast as before and five times faster compared to DALL-E 3. This efficiency makes KOALA a game-changer in the field.

What is the LAION-aesthetics-V2 6+ Dataset?

The LAION-Aesthetics V2 6+ dataset is a subset of the LAION 5B dataset, which is known for its high visual quality. This specific subset includes images that scored 6.5 or higher via aesthetics prediction models. These models were trained to predict the rating people gave when asked “How much do you like this image on a scale from 1 to 10?”. The dataset is used in various AI research and applications, particularly in training models like KOALA.

What is the ‘Ko-LLaVA’ Model?

The ‘Ko-LLaVA’ model, developed by the Electronics and Telecommunications Research Institute (ETRI), is a conversational visual-language model. It adds visual intelligence to conversational AI like ChatGPT. The model can retrieve images or videos and perform question-answering in Korean about them. It was developed in an international joint research project with the University of Wisconsin-Madison and ETRI. The model utilizes the open-source LLaVA (Large Language and Vision Assistant) with image interpretation capabilities at the level of GPT-4.

System Requirements For the KOALA Model

The KOALA model developed by ETRI is designed to run efficiently on GPUs. Specifically, the KOALA-700M model can generate a 1024×1024 image in less than 1.5 seconds on an NVIDIA 4090 GPU. However, the exact system requirements may vary depending on your specific setup and requirements.

Limitations of the KOALA Model

The KOALA model, despite its impressive capabilities, does have some limitations:

1. Text Rendering: The models face challenges in rendering long, legible text within images. This means that the model might struggle to generate images that contain a lot of text or require specific text to be legible.
2. Complex Prompts: KOALA sometimes struggles with complex prompts involving multiple attributes. This means that the model might not always accurately generate images when given complex or multi-faceted prompts.
3. Dataset Dependencies: The current limitations are partially attributed to the characteristics of the training dataset (LAION-aesthetics-V2 6+). This means that the model’s performance and capabilities might be influenced by the specific characteristics and limitations of the dataset it was trained on.
