🛠️ Technical Deep Dive
- HiDream-O1-Image is built on a Pixel-level Unified Transformer (UiT) architecture.
- It operates directly on raw pixels, eliminating the need for an external Variational Autoencoder (VAE) or disjoint text encoders.
- The model uses a single shared token space for raw pixels, text prompts, and task-specific conditions.
- The open-source version, HiDream-O1-Image (and its Dev variant), has 8 billion parameters.
- The commercial 'Pro' version (HiDream-O1-Image-Pro) features over 200 billion parameters.
- It supports native high-resolution image synthesis up to 2048x2048 pixels.
- The model incorporates a 'Reasoning-Driven Prompt Agent' that resolves implicit knowledge, layout, and text rendering before generation.
- It is designed for multiple tasks, including text-to-image generation, instruction-based image editing, subject-driven personalization, long-text rendering, and storyboard generation.
- The distilled Dev variant can converge in 28 inference steps with a guidance scale of 0, while the full model uses 50 steps with a CFG of 5.0.
