EvolveDirector explores whether an open text-to-image model can be trained with public resources by using public APIs of advanced models to create text-image pairs. Experiments show generated data helps match advanced capabilities, but large-scale samples (10M+) are costly. The framework uses pre-trained large vision-language models to iteratively discriminate, expand, delete, and mutate training data, reducing required volume.

However, most of them are trained on proprietary high-quality data, and some models withhold their parameters and only provide accessible application programming interfaces (APIs), limiting their benefits for downstream tasks. To explore the feasibility of training a text-to-image generation model comparable to advanced models using publicly available resources, we introduce EvolveDirector. This framework interacts with advanced models through their public APIs to obtain text-image data pairs to train a base model. Our experiments with extensive data indicate that the model trained on generated data of the advanced model can approximate its generation capability. However, it requires large-scale samples of 10 million or more. This incurs significant expenses in time, computational resources, and especially the costs associated with calling fee-based APIs. To address this problem, we leverage pre-trained large vision-language models (VLMs) to guide the evolution of the base model. VLM continuously evaluates the base model during training and dynamically updates andrefines the training dataset by the discrimination, expansion, deletion, and mutation operations. Experimental results show that this paradigm significantly reduces the required data volume. Furthermore, when approaching multiple advanced models, EvolveDirector can select the best samples generated by them to learn powerful and balanced abilities. The final trained model Edgen is demonstrated to outperform these advanced models.

While these models benefit from publicly available datasets such as ImageNet [5], LAION [6], and SAM [7], they rely more heavily on proprietary, high-quality data collections that surpass the quality of publicly accessible datasets. Models such as Midjourney [4] are particularly noted for deriving substantial benefits from their internal datasets. However, given the significant commercial advantages brought by their impressive capabilities, most advanced models keep their parameters private, hindering reproducibility and democratization. In this paper, we aim to explore training an open-source text-to-image model with public resources to achieve comparable capabilities with the existing advanced models.  \n∗ Corresponding Author.  \n38th Conference on Neural Information Processing Systems (NeurIPS 2024) .  \nFour superheroes stand in front of the pyramids, from left to right, Batman, Hulk, Iron Man, and Spider-Man.  \nThree transparent glass bottles on a wooden table.
