CogCanvas: A Benchmark for Evaluating Multi-Subject Reference-Based Image Generation

CogCanvas is a new benchmark for multi-subject reference-based image generation, featuring 1,952 curated reference images of 100 celebrities, 115 objects/fashion items, and 29 real-world backgrounds. It generates 1,361 compositional prompts with 2–5 people, using a pipeline that includes DINOv2 deduplication, aesthetic filtering, and automated graph derivation for interaction and positioning. The benchmark evaluates three tasks—reference-based multi-human-object generation, text-to-image compositional generation, and reference retrieval—under a six-axis protocol, and introduces BG‑Sim and Attr‑VQA metrics to assess background fidelity and attribute binding.

From Corpora to Co-Evolving Capabilities: Capability-Centric Data Design for Generalist Image Generation

The paper introduces a capability‑centric data infrastructure for generalist image generation, integrating task‑specific supervision with a curriculum that aligns with the dependencies among generative capabilities. It employs three interoperable data engines—text‑image grounding, inter‑image transformation, and image‑knowledge association—alongside caption experts to harmonize text‑to‑image and editing supervision. The system curates massive corpora (440M T2I images, 120M editing pairs, 27M image‑entity pairs) and trains multimodal diffusion models (3B and 6B parameters) from scratch, achieving broad visual coverage and versatile rendering as shown by CPI‑Bench and qualitative tests.

Beyond Pairwise Preferences: Listwise Reward-Aware Alignment for Diffusion Models

The paper introduces Diffusion LAIR, a listwise preference optimization technique that leverages continuous reward scores instead of binary pairwise comparisons to align text‑to‑image diffusion models. LAIR transforms reward scores into centered advantage weights and optimizes an advantage‑weighted regression objective on an implicit reward defined by denoising‑loss improvement over a reference model, with a quadratic penalty to regulate reward magnitude. Experiments demonstrate that Diffusion LAIR surpasses strong baseline methods on SD1.5 and SDXL across generation, compositional, and editing tasks.

Towards Fine-Grained Text-to-3D Quality Assessment: A Benchmark and A Two-Stage Rank-Learning Metric

The paper introduces T23D-CompBench, a new benchmark for fine‑grained text‑to‑3D quality assessment that includes 3,600 textured meshes generated from ten state‑of‑the‑art models and 129,600 human ratings. It also proposes Rank2Score, a two‑stage rank‑learning metric that first trains with supervised contrastive regression and curriculum learning, then refines predictions using mean opinion scores to better align with human judgments. Experiments show Rank2Score outperforms existing metrics and can be used as a reward function for generative model optimization.
