Runway has introduced the Gen-3 Turbo update, significantly increasing the speed of its image-to-video generation process. The new Turbo mode is seven times faster than previous versions, allowing users to create high-quality videos more efficiently.
New Noteworthy Papers??
Abstract: Recent advancements in long context large language models (LLMs) have significantly expanded their ability to process inputs up to 100,000 tokens. However, these models struggle to generate outputs longer than 2,000 words, a limitation rooted in the characteristics of the Supervised Fine-Tuning (SFT) datasets. To address this, the paper introduces AgentWrite, a pipeline that decomposes ultra-long generation tasks into subtasks, enabling LLMs to produce coherent outputs exceeding 20,000 words. By creating the LongWriter-6k dataset and incorporating it into model training, the authors successfully scale output lengths to over 10,000 words. The paper also introduces LongBench-Write, a benchmark for evaluating ultra-long generation capabilities, with their 9B parameter model achieving state-of-the-art performance.

Abstract
Language models (LMs) have shown promise in various decision-making tasks but are limited by simple acting processes. The paper introduces Language Agent Tree Search (LATS), a framework that integrates reasoning, acting, and planning within LMs. By combining Monte Carlo Tree Search with LMs' in-context learning and incorporating environment-based feedback, LATS enhances exploration and decision-making. The approach shows significant improvements, achieving state-of-the-art results in programming accuracy and competitive performance in web navigation, while maintaining or improving reasoning capabilities.
Key Highlights
Impact Statement
LATS enhances LM performance through iterative decision-making and reflection, which may improve interpretability and alignment but also raises security risks. Further research is encouraged to address these concerns and optimize the framework's efficiency.

Abstract
EfficientRAG introduces a novel retriever designed to handle multi-hop question answering more efficiently. Unlike traditional Retrieval-Augmented Generation (RAG) methods that rely on multiple calls to large language models (LLMs), EfficientRAG generates queries iteratively without requiring LLM calls at each step. This approach filters out irrelevant information and has been shown to outperform existing RAG methods across three open-domain multi-hop question-answering datasets.

Abstract
RAGCHECKER introduces a comprehensive evaluation framework for Retrieval-Augmented Generation (RAG) systems. Addressing the challenges of evaluating complex, modular RAG systems, RAGCHECKER provides a suite of diagnostic metrics for both retrieval and generation modules. Unlike existing evaluation methods, which often lack granularity and reliability, RAGCHECKER employs claim-level entailment checking to offer fine-grained insights into system performance. The framework has been validated through meta-evaluation, showing superior correlation with human judgments compared to other metrics. Extensive experiments with eight RAG systems across ten domains demonstrate RAGCHECKER's ability to reveal meaningful patterns and trade-offs in RAG architectures, guiding improvements and enhancing system development.

Abstract
rStar introduces a novel self-play mutual reasoning approach designed to enhance the reasoning capabilities of small language models (SLMs) without the need for fine-tuning or superior models. This method employs a two-step process involving mutual generation and discrimination. Initially, a target SLM uses Monte Carlo Tree Search (MCTS) augmented with human-like reasoning actions to create high-quality reasoning trajectories. Another SLM, with comparable capabilities, acts as a discriminator to validate these trajectories. Trajectories that receive mutual agreement are deemed more reliable. Experiments across five SLMs demonstrate that rStar significantly improves performance on various reasoning tasks, including GSM8K, GSM-Hard, MATH, SVAMP, and StrategyQA, with notable accuracy gains.

Abstract
FruitNeRF is a novel framework for fruit counting that utilizes advanced view synthesis methods to perform accurate 3D fruit counting from a set of unordered images captured by a monocular camera. The framework employs a foundation model to generate binary segmentation masks for various fruit types, regardless of their type. By combining RGB and semantic information, FruitNeRF trains a semantic neural radiance field to produce fruit-only point clouds through uniform volume sampling. This approach, leveraging neural radiance fields, enhances fruit counting accuracy by addressing issues such as double counting and irrelevant fruit detection. Evaluations using both real-world and synthetic datasets demonstrate that FruitNeRF achieves high accuracy, with F1-scores of 0.95 on synthetic data and 0.79 on the Fuji benchmark dataset.

Abstract
The xGen-MM framework, also known as BLIP-3, is a comprehensive approach for developing Large Multimodal Models (LMMs). This framework builds on the Salesforce xGen initiative and incorporates meticulously curated datasets, a training recipe, model architectures, and a suite of resulting LMMs. Key advancements include enhanced training data richness and diversity, a scalable vision token sampler replacing Q-Former layers, and a unified training objective that simplifies the training process. xGen-MM models, including a pre-trained base model, an instruction-tuned model, and a safety-tuned model with DPO (Deterministic Prompt Optimization), demonstrate strong in-context learning capabilities and competitive performance among open-source LMMs. The safety-tuned model aims to reduce harmful behaviors such as hallucinations. All models, datasets, and fine-tuning code are open-sourced to advance LMM research. Resources will be available on the project page.
