OpenAI has taken a surprising turn, deciding to open-source its technology. Following the recent release of a paper about the Consistency Model, the company has decided to share its AI art generation technology with the public. OpenAI has been criticized for its closed door policy, but this move towards open source marks a change in direction. The company has also announced a bug bounty program to encourage researchers to find and report system bugs.

Consistency Model: A Breakthrough in AI Art Generation

Consistency models are generative models designed for one-stage and few-stage generation. According to OpenAI’s paper, the application of consistency distillation outperforms the diffusion model approach in various benchmarks. These models enable zero-shot image editing applications, such as colorization, painting, denoising, interpolation, and stroke-guided generation, much like diffusion models. However, coherence models require significantly less computational power, allowing quicker results on single devices.

the brains behind the research

Authors of the paper include Ilya Sutskever, creator of ChatGPT; Yang Song; Mark Chen; and Prafulla Dhariwal. Although diffusion models outperformed GANs in image, audio, and video generation, their iterative generation process limited the sampling speed and capacity for real-time applications. Consistency models overcome this limitation by providing high sample quality without adversarial training. This allows for a fast one-stage generation or at most two stages.

How do association models work?

Similar to diffusion models, coherence models work by training the model to observe the noise process of an image. However, this model can pick an image at any level of ambiguity and generate a correct image in a single step, even when it is fed with missing information. As a result, convolutional models can obtain final results very quickly, even with noisy images.

Why do consistency models matter?

The development of consistency models is important because machine learning research typically involves establishing a technique, improving upon it, and then fine-tuning it over time, while adding computation to produce better results. This is how the modern diffusion model and ChatGPT came into existence. However, this process is self-limiting due to practical limits on how much computation can be devoted to a given task.

The next step involves the creation of a new, more efficient technology that initially performs poorly but is vastly more efficient than previous models. Coherence models demonstrate this potential, although direct comparisons with diffusion models are still premature.
