颠覆传统！Lumina-mGPT 可以从文本中创建逼真且高分辨率的图像
多模态生成模型正引领人工智能新潮流，专注于融合视觉与文本数据，以创造多功能AI系统，执行从图像生成到跨数据类型理解与推理的多种任务。其中，关键挑战是提升自回归（AR）模型能力，使其能根据文本描述生成高细节图像。尽管扩散模型在生成高质量图像方面表现出色，AR模型在图像质量、分辨率灵活性及多任务处理能力上相对滞后。上海AI实验室和香港中文大学的研究人员推出Lumina-mGPT，一种基于解码器-only的变换器架构，采用多模态生成预训练方法，旨在克服AR模型限制，实现与扩散模型同等水平的逼真图像生成，同时保持简便性和可扩展性。Lumina-mGPT采用详尽的灵活渐进的监督微调策略，增强图像生成能力，支持高分辨率图像生成（1024×1024像素），细节丰富且与文本提示高度一致。该模型在图像质量、视觉一致性及多种任务支持方面超越前代模型，仅需较小数据集即可实现卓越性能，预示未来AI系统将更加复杂与多才多艺。
