2024.06.28 We have removed the weights and code that may have used potentially unauthorized datasets in the current stage. We will update the checkpoints after the Microsoft RAI process.

• We identify two crucial requirements of text encoders for achieving accurate visual text rendering: character awareness and alignment with glyphs. To this end, we propose a customized text encoder, Glyph-ByT5, by fine-tuning the character-aware ByT5 encoder using a meticulously curated paired glyph-text dataset.

• We present an effective method for integrating Glyph-ByT5 with SDXL, resulting in the creation of the Glyph-SDXL model for design image generation. This significantly enhances text rendering accuracy, improving it from less than 20% to nearly 90% on our design image benchmark. Noteworthy is Glyph-SDXL's newfound ability for text paragraph rendering, achieving high spelling accuracy for tens to hundreds of characters with automated multi-line layouts.

• We deliver a powerful customized multilingual text encoder, Glyph-ByT5-v2, and a strong aesthetic graphic generation model, Glyph-SDXL-v2, that can support accurate spelling in $\sim10$ different languages
