Brief

Researchers have introduced Lens, a 3.8B-parameter text-to-image model that achieves competitive performance with significantly less training compute than larger models, using dense caption datasets and efficient architecture. It generates high-resolution images quickly and supports multilingual prompts. Separately, a new framework called RankE has been developed for discrete text-to-image models, which jointly optimizes the generator and decoder to improve both alignment and image fidelity, addressing issues of latent covariate shift.

Microsoft has released Lens and Lens-Turbo, two foundational text-to-image models available on Hugging Face. These 3.8 billion parameter models are designed for efficient training and fast generation of high-resolution images. They utilize techniques like dense-caption pre-training and mixed-resolution learning to achieve competitive quality with less computational cost than larger models. AI
