Moonworks Lunara: Modeling Artistic Intelligence [R]
Moonworks Lunara introduces a novel Diffusion Mixture Transformer architecture with fewer than 10B active parameters for image generation, aiming to model artistic intelligence. Evaluation involved 1,000 shared prompts and 8,000 generated images, assessing aesthetic quality, emotional resonance, and content integrity against seven baselines including GPT-Image-1 Mini, Qwen-Image, and SD 3.5 Turbo. This release follows previous open-source dataset releases, hoping to motivate further research in active learning and mixture-based architectures for image generation.

Lunara introduces a novel Diffusion Mixture Transformer architecture with fewer than 10B active parameters for modeling artistic intelligence in image generation.
Its CAT training algorithm iteratively updates the training distribution through targeted sample acquisition, image refinement, and selective inclusion of human-created artwork inspired by principles of active learning. Semantic variations modify composition while preserving shared content, providing controlled neighborhoods of related training examples.
Evaluation uses 1,000 shared prompts and 8,000 generated images, measuring aesthetic quality, emotional resonance, and content integrity. The seven baselines are GPT-Image-1 Mini, Qwen-Image, AuraFlow, SD 3.5 Turbo, HiDream-I1 Fast, FLUX-Klein-4B, and Z-Image-Turbo.
Under GPT-5.6 Sol evaluation, Lunara leads aesthetic quality at 8.473, versus 8.457 for GPT-Image-1 Mini and 8.366 for Qwen-Image; GPT-Image-1 Mini leads emotional resonance and content integrity.
In the blinded human evaluation, six evaluators assess anonymized image pairs; Lunara achieves the highest mean scores across all three dimensions.
