Meta, formerly known as Facebook, claims to have achieved a breakthrough in AI-powered image generation with its latest model, CM3Leon. The company asserts that CM3Leon sets a new standard for text-to-image generation and is one of the first image generators capable of producing captions for images. This development paves the way for more advanced image understanding models in the future, according to Meta.
While previous image generators have made incremental improvements in quality, the performance of AI-powered image generators has remained inconsistent. However, Meta believes that CM3Leon’s capabilities represent a significant leap forward. By leveraging transformer models and the attention mechanism, CM3Leon demonstrates state-of-the-art performance in generating coherent imagery that aligns with input prompts.
Unlike many existing image generators that rely on computationally intensive diffusion processes, CM3Leon’s transformer model offers greater efficiency and speed. It requires five times less compute power and a smaller training dataset compared to previous transformer-based methods. This efficiency makes CM3Leon more practical for real-time applications.
To train CM3Leon, Meta used a dataset of millions of licensed images from Shutterstock. The model boasts over 7 billion parameters, more than twice the number in OpenAI’s DALL-E 2. Meta also employed a technique called supervised fine-tuning, which has proven effective in training text-generating models like OpenAI’s ChatGPT. By applying this technique to image generation, CM3Leon achieves enhanced performance not only in generating images but also in writing image captions and responding to text instructions.
CM3Leon demonstrates remarkable proficiency in generating images based on complex prompts and exhibits improved understanding of various constraints. The model produces detailed and contextually appropriate images, even in response to challenging instructions. In comparison to other image generators, CM3Leon consistently generates images that closely align with the given prompts.
While Meta acknowledges the challenges of bias in generative AI models, it does not specifically address the issue in relation to CM3Leon. However, the company emphasizes the importance of transparency in addressing these challenges and accelerating progress in the AI industry.
Meta has not announced any specific plans for the release of CM3Leon, and given the ongoing discussions surrounding open-source art generators, its availability remains uncertain.
