    "body_text": "Modern text-to-image systems commonly inherit an internet-scale language model. Halcyon instead trained from scratch on 100 million image-text pairs. The authors report that a 520-million-parameter version beat a larger LlamaGen comparison with 18.2 times less pretraining compute, while a 1.6-billion-parameter model beat the evaluated JiT-T2I system with 275 times less compute. Controlled experiments found no image-generation benefit from text-only pretraining. The reported metrics do not settle every dimension of quality, but they challenge the assumption that an image generator must first become a broadly pretrained language model.",
