[1] MagicQuill: An Intelligent Interactive Image Editing System

MagicQuill is an advanced image editing system designed for efficient and precise manipulation tasks. It offers a streamlined interface that supports operations like inserting elements, erasing objects, and altering colors with minimal input. A multimodal large language model (MLLM) anticipates user intentions in real time, eliminating the need for explicit prompts. A powerful diffusion prior, enhanced by a two-branch plug-in module, ensures precise control over edits. Experimental results showcase MagicQuill's ability to deliver high-quality image editing results swiftly and effectively. [Link ]

[2] Large Language Models Can Self-Improve in Long-context Reasoning

Large language models excel in processing long contexts but face challenges in long-context reasoning. Existing methods rely on synthetic data annotated by experts or advanced models like GPT-4, limiting progress. This paper introduces \ours, a self-improvement approach where multiple outputs are sampled for each question, scored with Minimum Bayes Risk, and used for supervised fine-tuning or preference optimization. Experiments show \ours improves Llama-3.1-8B-Instruct by 4.2 points and outperforms methods relying on human or advanced model annotations. This approach paves the way for self-improvement techniques in long-context reasoning, advancing LLM capabilities. [Link ]

[3] LLaMA-Mesh: Unifying 3D Mesh Generation with Language Models

This work introduces LLaMA-Mesh, a novel approach enabling LLMs pretrained on text to generate 3D meshes and interpret them in a unified framework. By tokenizing 3D mesh data as plain text, LLaMA-Mesh seamlessly integrates spatial knowledge embedded in LLMs without expanding their vocabulary. A supervised fine-tuning dataset allows the model to generate meshes from text prompts, produce interleaved text and 3D outputs, and understand 3D structures. This approach unifies 3D and text modalities, achieving mesh generation quality comparable to specialized models while retaining strong text generation capabilities. [Link ]

[4] Artificial Intelligence, Scientific Discovery, and Product Innovation

This study examines AI's impact on innovation, analyzing the introduction of an AI-driven materials discovery tool among 1,018 scientists in a U.S. R&D lab. Researchers using AI discovered 44% more materials, leading to a 39% increase in patent filings and a 17% rise in product innovation, with more novel and radical inventions. However, benefits varied: top scientists doubled output by leveraging domain expertise to prioritize AI suggestions, while others struggled with false positives. AI automated 57% of idea-generation tasks, reallocating effort to evaluating model outputs. Despite these gains, 82% of scientists reported reduced job satisfaction due to decreased creativity and underutilized skills. [Link ]

[5] OmniEdit: Building Image Editing Generalist Models Through Specialist Supervision

This paper introduces \omniedit, a versatile image editing model addressing limitations in existing methods, such as biased training data, noisy datasets, and fixed low-resolution aspect ratios. \omniedit supports seven editing tasks across various aspect ratios and resolutions. Key contributions include: (1) supervision from seven specialist models for comprehensive task coverage, (2) improved data quality using importance sampling based on large multimodal model scores (e.g., GPT-4o), (3) a novel EditNet architecture to enhance editing success, and (4) diverse aspect ratio training for real-world applicability. Evaluations show \omniedit significantly outperforms current models in both accuracy and versatility. [Link ]

[6] Add-it: Training-Free Object Insertion in Images With Pretrained Diffusion Models

Add-it is a training-free approach for text-guided object addition in images, addressing challenges of preserving scene structure and natural object placement. It extends diffusion models' attention mechanisms to integrate information from the scene image, text prompt, and generated image, ensuring structural consistency and plausible placement. Without fine-tuning, Add-it achieves state-of-the-art performance on image insertion benchmarks, including the newly introduced "Additing Affordance Benchmark." Human evaluations prefer Add-it in over 80% of cases, and it outperforms supervised methods across various automated metrics. [Link ]

[7] LLM2CLIP: Powerful Language Model Unlocks Richer Visual Representation

LLM2CLIP leverages LLMs like GPT-4 and LLaMA to enhance CLIP's multimodal representation capabilities. By fine-tuning LLMs in the caption space using contrastive learning, the approach extracts LLMs' advanced textual understanding into CLIP's embeddings, improving its ability to handle longer, more complex captions. The fine-tuned LLM serves as a teacher for CLIP's visual encoder, expanding its learning efficiency and overcoming limitations of vanilla CLIP's text encoder. Experiments show that LLM2CLIP significantly improves performance in cross-modal tasks, unlocking new potential for multimodal representation learning. [Link ]
